57699b1fa6 feat: add gpg integration
This commit adds gpg system integration. This is done through two new
packages: gpgbin, which handles the system calls and parsing; and gpg
which is mostly a copy of emersion/go-pgpmail with modifications to
interface with package gpgbin. gpg includes tests for many cases, and
by it's nature also tests package gpgbin. I separated these in case an
external dependency is ever used for the gpg sys-calls/parsing (IE we
mirror how go-pgpmail+openpgp currently are dependencies)

Two new config options are introduced:
* pgp-provider. If it is not explicitly set to "gpg", aerc will default to
it's internal pgp provider
* pgp-key-id: (Optionally) specify a key by short or long keyId

698c0957d7 pgp: ensure CRLF line endings in pgpmail reader
Ensure CRLF line endings in the pgpmail reader. Fix the pgp signature
verification for maildir and notmuch.

These backends do not return the full message body with CRLF
line endings. But the accepted OpenPGP convention is for signed data to
end with a <CR><LF> sequence (see RFC3156).

If this is not the case the signed and transmitted data are considered
not the same and thus signature verification fails.

f6e34e4cf1 imap: fix no-envelope-for-message error
Fix the "no envelope available for this message" error that can occur
when using the same imap mailbox in another mailclient (e.g.
through a webmail interface) at the same time.

Complements the fixes in commit 7fe7fe4 ("ui: fix panic in header
formatter") and commit 074b0a1 ("view,list: fix crash when viewing
incomplete imap messages").

The error is caused when a message attribute update is received by the
message store before the message list had a chance to fetch the proper
header first. In this case, an (incomplete) message info is stored in
the message store and the message list will never fetch the correct
header. To prevent this, add only messages to the store with a non-nil
envelope but make sure that message attribute updates are properly
merged.

e50ab59284 sort: keep sort criteria applied to folder
Keep the sort criteria applied to the selected folder until the default
sort order should be restored. Call the sort command without arguments
to restore the default sort order.

The current behavior is that the default sort order is restored as soon
as the folder reloads. This happens often and then the results of the
sort command are lost. This makes the sort command not very
user-friendly. Instead, we should keep the sort criteria applied until
the user explicitly wants to restore the default sort order again.

ae83373fa6 logging: added a log on panic
Since panics still regularly "destroy" the terminal, it is hard to get a
stack trace for panics you do not anticipate. This commit adds a panic
handler that automatically creates a logfile inside the current working
directory.

It has to be added to every goroutine that is started and will repair
the terminal on a panic.

9f4da4de0c msglist: update message counter upon filter change
Update message counter in msglist when the filter is changed (either set or
cleared in the msgstore).

When we apply a filter, we change the number of uids in the message
store. This can unintentionally trigger the storeUpdate() function of
the msglist which checks the number of uids for new messages and
advances the pointer by the difference in the number of messages. This
can be avoided when we update the message counter upon changing the
filter.

b19b844a63 pgp: PGP/MIME encryption for outgoing emails
implements PGP/MIME encryption with go-pgpmail. The Encrypt() function of
go-pgpmail requires a list of public keys which are taken from the
keystore. The keystore is searched for the email addresses of all
recipients (to, cc, and bcc).
If you want to be able to read the encrypted email afterwards, add
yourself as a recipient in either to, cc, or bcc as well.

Public keys can be exported from gpg into aerc as follows:
$ gpg --export  >> ~/.local/share/aerc/keyring.asc

When composing a message, the encryption is enabled with the
":encrypt" command. This sets a bool flag in the Composer struct.
A reapted application of this command will toggle the flag.
The encrypted message can also be signed by using the ":sign"
command before or after ":encrypt".

in aerc's copy of the keyring.

Private keys can be exported from gpg into aerc as follows:
$ gpg --export-secret-keys  >> ~/.local/share/aerc/keyring.asc

A message is signed with the ":sign" command. The sign command sets
a bool flag in the Composer struct. Using the command repeatedly will
toggle the flag.

Go 1.15 handles "" in the address parser as a non error case, returning

c846307144 base models.Address on the mail.Address type
This allows us to hook into the std libs implementation of parsing related stuff.
For this, we need to get rid of the distinction between a mailbox and a host
to just a single "address" field.

However this is already the common case. All but one users immediately
concatenated the mbox/domain to a single address.

So this in effects makes it simpler for most cases and we simply do the
transformation in the special case.

f4dc7e1f74 Add oauthbearer support for SMTP
This piggybacks on the existing IMAP support, and uses the same
configuration format (my local testing example has the IMAP and SMTP
lines almost copy-pasted from one another).

`Send()` command, but it's a start...

f1a0fd20d6 improve date parsing for notmuch/maildir
If a message date would fail to parse, the worker would never receive
the MessageInfo it asked for, and so it wouldn't display the message.

The problem is the spec for date formats is too lax, so trying to ensure
we can parse every weird date format out there is not a strategy we want
to pursue. On the other hand, preventing the user from reading and
working with a message due to the error format is also not a solution.

The maildir and notmuch workers will now fallback to the internal date, which
is based on the received header if we can't parse the format of the Date header.

The UI will also fallback to the received header whenever the date header can't
be parsed.

This patch is based on the work done by Lyudmil Angelov <lyudmilangelov@gmail.com>
But tries to handle a parsing error a bit more gracefully instead of just returning
the zero date.

0535f6333f Add additional flagging functionality
More mail flags can now be set, unset, and toggled, not just the
read/seen flag.

This functionality is implemented with a new `:flag` and `:unflag`
command, which are extensions to the matching `:read` and `:unread`
commands, adding support for different flags.  In fact, the
`read`/`unread` commands are now recognized aliases to `flag`/`unflag`.
The new commands are also well documented in aerc(1).

The change mostly extends the previous read/unread setting functionality
by adding a selection for the flag to change.

72f55b857b lib: fix an out of bounds panic in the server
If the message doesn't contain ':', we don't properly discard the
message, so we end up slicing it like msg[:-1].

This can be reproduced if one runs 'aerc foo', as the server receives
'foo' as the message.

'aerc foo' still doesn't do anything very user friendly, but at least it
doesn't panic horribly.

While at it, do the 'got message' log at the very beginning, so that the
user can see what message the server got before reporting the command as
invalid.

07a9b9204e Don't select completions until tab has been pressed
Before, pressing <Enter> when completions were visible would execute the
selected completion. As soon as completions were provided, the first
item would be selected. This could cause issues e.g. when changing
folders:

  :cf <Enter>

Previously, this would have selected the first folder in the list. Now,
since <Tab>, <C-n>, etc have not been pressed to select the first
completion, the command above simply executes `:cf `.

To accomplish this, a "no-op completion" has been added at index -1.

A popover is a special UI element which can be layered over the rest of
the UI (i.e. it is painted last) and can fall anywhere on the screen,
not just with the bounds of its parent's viewport/context. With these
special abilities comes the restriction that only one popover may be
visible on screen at once.

Popovers are requested from the UI context passed to Draw calls and
specify the anchor point and the desired dimensions. The popover is then
fit to the available space and placed relative to the anchor point.

This change simply checks whether the make is going to be valid before
starting to work on the actual delete. If there are more messages queued
to be deleted than what's left in the store, then we're obviously in an
inconsistent state, ask for an update and break.

At the top level when a mouse event is received it is passed to the

that can actually handle it, such as the tablist, dirlist or msglist.

A mouse event is passed so that components can handle other things such
as scrolling with the mousewheel. The components themselves then perform
the necessary actions.

Clicking emails in the messagelist opens them in a new tab.

Textinputs can be clicked to position the cursor inside them.

Mouseevents are not forwarded to the terminal at the moment.

Elements which do not handle mouse events are not required to implement
the Mouseable interface.

Sometimes I observe out-of-order messages when using a maildir inbox. It
appears that the UIDs for these messages are returned out of order by
the MessageStore. In order for a maildir MessageStore to return messages
in most recently received order, it must have already opened all
messages and parsed the date to use as a sort key. Rather than implement
that, simply sort messages by time as we display. This fix shows my
emails in order.

Leave it up to the user whether or not they want to rebind the key in
[compose].

152f8c9519 Ring bell when new messages arrive
Add a "new-message-bell" option to the UI section of aerc.conf. A new
hook into the message store allows the msglist widget to detect new
messages being added to the displayed list. When new messages are
delivered, and the new-message-bell option is enabled (as it is by
default), the terminal will beep.

2804f00001 lib/msgstore: Fix Select, Next, Prev with filter
When filter is active we want to use store.results instead of
store.uids, since we are dealing with a subset of the uids. Otherwise
any methods involving len will have undefined behavior.

7a3765a36b Fix tabstrip over-drawing when not enough space
Tabstrip didn't take into account the width of the context. Now, it just
shows as many tabs as can fit and truncates the last one if necessary.

In future it probably would be best to ensure that the selected tab is
rendered on the screen.

cded067bc3 Add tab completion to textinputs
This adds tab completion to textinput components. They can be configured
with a completion function. This function is called when the user
presses <tab>. The first completion is initially shown to the user
inserted into the text. Repeated presses of <tab> or <backtab> cycle
through the completions list. The completions list is invalidated when
any other non-tab-like key is pressed.

Also changed is some logic for current completion generation so that
all available commands are returned when <tab> is pressed with no
current text and similarly for arguments of commands.

Aerc will keep track of the previous 1000 commands, which the user can
cycle through using the arrow keys while in the ex-line. Pressing up
will move backwards in history while pressing down will move forward.

1b673b5ea7 Move msgstore map to dirstore
This map represents a mapping from directory names to their associated
messagestores anyway so they should be under dirstore. This simply moves
them there and adds some methods required to interact with them.

dc4c36adbf Add new-email trigger
This patch sets up the trigger config section of aerc.conf.

Each trigger has its own function which is called from the place where
it is triggered. Currently only the new-email trigger is implemented.

The triggers make use of format strings. For instance, in the new-email
trigger this allows the user to select the trigger command and also the
information extracted from the command and placed into their command.

To actually execute the trigger commands the keypresses are simulated.

Further triggers can be implemented in the future.

Formatting of the command is moved to a new package.

ee5b537d53 Fix :close on terminal panic
Executing :close on a terminal would panic due to it already having been
removed.

This is also related to the fact that removing a tab doesn't check for
whether it actually found a tab to remove or not.

1cf90897f7 Fix grid creating too large subcontexts
The grid was not checking there was enough space for the cells so would
just attempt to create subcontexts that don't actually fit.

This attempts to use the remaining space and then if there is no space
then it just skips drawing this cell.

e42b95a617 Add change tab command
This command allows the user to change tab by giving the tab name. This
can be tab completed too. The previous tab is stored in the tabs module
so that when a new tab is created it is still possible to go to the
previous one.

Normal invocation is :ct folder
Previous tab is :ct -
