ca90343850 outgoing-cred-cmd: delay execution until an email needs to be sent
This can be useful in cases when:

1. outgoing-cred-cmd requires a user action or confirmation (e.g. when
   using pass with a Yubikey or similar smart card that requires a user
   to enter a pin or touch the device when decrypting the password)

2. A user starts aerc frequently, but not all the sessions end up with
   sending emails

3. So the user only wants to execute outgoing-cred-cmd when the password
   is really used, so the user doesn't have to enter pin or touch their
   Yubikey each time aerc starts

54a0a377e0 threads: debounce client-side thread building
Debounce client-side thread building in the message store. Debouncing is
useful when multiple messages are loaded, i.e. when scrolling with
PgUp/PgDown.

Without the debouncing, all client-side threads will be built everytime
the message store is updated which creates a noticable lag in the
message list ui when client-side threading is activated.

The default debouncing delay can be changed by changing
'client-threads-delay' in the UI config section.

ccd042889f threading: add force-client-threads option
This patch adds a config option to force the use of client side threads.
This option will override a servers Thread capability, and only build
threads on the client. It can be enabled contextually. For example:

	[ui]
	threading-enabled = true

	[ui:folder~^Archive]
	force-client-threads = true

This config would enable threads for all views, and use client threads
for folders that start with Archive. This can be advantageous if, for
example, the folder is very large and the server has a slow response due
to building threads for the entire mailbox

4240f1fbfd perf: reduce calls to GetUiConfig
GetUiConfig was being called many times, and came up as a high CPU user
in a cpuprofile. Every call would merge a UIConfig, which is a costly
operation. Ideally, we would only need to have a config for every
account X every directory. We also have a context for subjects. This
patch stores all FOLDER and ACCOUNT level configs and reuses those
merged objects. The SUBJECT contexts are not stored in favor of merging
on-the-go, with a TODO comment to deprecate that feature and implement a
better per-message styling option. I suspect this feature is not used
very much.

Before applying this patch with my setup, GetUiConfig is called 1159
times just to open aerc. After applying, this is reduced to 37.

de24d2d590 config: fix setting of zero-value time.Duration config values
When using section.MapTo(struct) (go-ini), if the struct has a default
value for a time.Duration type, a zero-value in the config will not
overwrite the default. If the type is *time.Duration, it will be
overwritten properly. One consideration was to change all
time.Duration types to *time.Duration. This method was chosen for ease
of implementation.

For example, if you set dirlist-delay = 0s, the delay will be 200ms.
This can be observed by logging the value just after mapping the ui
section in config.go. A config value of 0.1ms will have a delay of
0.1ms.

Currently, aerc has 4 time.Duration config values:
1. DirlistDelay - default 200 ms
2. CompletionDelay - default 250 ms
3. CheckMail - default unset (0)
4. CheckMailTimeout - default 10 s

1, 2, and 4 have a non-zero default value and are subject to this bug.
Only 1 and 2 are fixed in this patch. Number 4 would not make sense to
have a 0 second timeout, therefore we can prevent the user from doing
this by keeping it as it is.

Another option could be to set these to 0 in config.go. The default
config (aerc.conf) has these keys in it with their default values.
Presumably, we don't need to set them again in config.go. If a user
deletes the config values out of aerc.conf, the UI will function but
with 0s delays.

83e0e2638d msgviewer: parse and display authentication results
Parse the Authentication-Results header and display it in the message
viewer (not enabled by default). DKIM, SPF and DMARC authentication
methods are supported. Implement recommendation from RFC 7601 Sec 7.1 to
have an explicit list of trustworthy hostnames before displaying the
authentication results. Be aware that the authentication headers can be
forged.

To display the results for a specific authentication method, add the
corresponding name to the layout of headers in the viewer section of
aerc.conf, e.g. to display all three, use:

header-layout = From|To,Cc|Bcc,Date,Subject,DKIM|SPF|DMARC

More information will be displayed when "+" is appended to the
authentication method name, e.g. DKIM+ or SPF+ or DMARC+.

Also, add the trustworthy hosts per account with the trusted-authres
parameter, e.g.

trusted-authres = *

to trust every host or use regular expressions for a finer control.
Multiple hosts can be entered as a comma-separated list. Authentication
results will only be displayed when the host is listed in the
trusted-authres list.

An optional timeout can be used with maildir/notmuch. Default is 10s

New account options:
check-mail
check-mail-cmd (maildir/notmuch only)
check-mail-timeout (maildir/notmuch only), default 10s
check-mail-include (IMAP only)
check-mail-exclude (IMAP only)

If unset, or set less than or equal to 0, check-mail will be ignored

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

74366d895d viewer: add key passthrough mode
When trying to search in less, keys bound to viewer functions can't be
used as part of the search query, which makes the search useless.

Add a view::passthrough binding mode and a :toggle-key-passthrough
command go toggle in and out of that mode. By default, typing '/' in the
viewer is bound to enabling key passthrough and automatically inserting
'/', to easily enter "less" search mode. When in the passthrough mode,
all bindings are ignored by default. The default binds.conf only defines
a single keybinding in that mode: <Esc> to get back out. $ex is bound to
<C-x> to allow typing colons.

175d0efeb2 binds: add account specific bindings
When using aerc for multiple accounts often bindings might differ
slightly between accounts. For example:

* Account A archives to one directory (:archive)
* Account B archives to monthly directories (:archive month)

Add account specific bindings to allow the user to add a "context" to a
binding group using a context specifier and a regular expression.

Currently the only context specifier is 'account'.

The regular expression is validated against the accounts loaded from
accounts.conf and the configuration fails to load if there are no
matches.

Contextual bindings are merged with global bindings, with contextual
bindings taking precedence, when that context is active.

Bindings are be configured using a generic pattern of
'view:context=regexp'. E.g.:

    # Globally Applicable Archiving
    [messages]
    A = :read<Enter>:archive<Enter>

    # Monthly Archiving for 'Mailbox' Account
    [messages:account=Mailbox$]
    A = :read<Enter>:archive month<Enter>

In the above example all accounts matching the regular expression will
archive in the monthly format - all others will use the global binding.

402612fd97 notmuch: allow sort by file order
When using the notmuch backend, it often makes more sense to sort
folders (actual virtual folders, or queries) by the order specified in
the query-map file, rather than alphabetically. This patch introduces a
configuration option (disabled by default) that allows this.

Additionally, due to the notmuch backend previously using maps (which
are order-undefined) to store the list of queries, default query
selection on aerc startup fluctuated. This patch fixes that by using
slices to store query order.

60c5a82a76 load config: do not overwrite the config upon error
It makes absolutely no sense to copy over the default template from aerc.conf
when the syntax is invalid and our ini parser fails.

The only valid case to do that is if the file is actually missing.

03650474e2 update tcell to v2 and enable TrueColor support
Also update to the tcell v2 PaletteColor api, which should keep the chosen
theme of the user intact.

Note, that if $TRUECOLOR is defined and a truecolor given, aerc will now stop
clipping the value to one of the theme colors.
Generally this is desired behaviour though.

20ec2c8eeb compose: use a proper header instead of a string map
Prior to this commit, the composer was based on a map[string]string.
While this approach was very versatile, it lead to a constant encoding / decoding
of addresses and other headers.

This commit switches to a different model, where the composer is based on a header.
Commands which want to interact with it can simply set some defaults they would
like to have. Users can overwrite them however they like.

In order to get access to the functions generating / getting the msgid go-message
was upgraded.
