4753cfd3e3 visual-mode: deselect messages after performing command
In order to better align to vim functionality: deselect visual mode
selections after performing a command on the selection. This patch also
introduces a new command to allow for re-selecting (remarking) the
previous selection set so that commands can be chained together. The
deselection only applies to msg commands that *do not* move the message
from the store (those types of commands already deselect):
- read/unread
- flag/unflag
- modify-labels
- copy
- pipe

Previous usage to mark several messages as read and deselect all:
Vjjj:read<Enter>:unmark -a<Enter>

New usage, similar to vim:
Vjjj:read<Enter>

To chain a command together:
Vjjj:read<Enter>:remark<Enter>{next command}<Enter>

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.

2551dd1bfa feat: add background mail polling option for all workers
Check for new mail (recent, unseen, exists counts) with an external
command, or for imap with the STATUS command, at start or on
reconnection and every X time duration

IMAP:
The selected folder is skipped, per specification. Additional config
options are included for including/excluding folders explicitly.

Maildir/Notmuch:
An external command will be run in the background to check for new mail.
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

0cc992b4e3 gpg: refactor tests for macos compatibility
Refactor lib/crypto/gpg tests to facilitate unit test runs on macos.
Macos creates temporary directories with names too long to call
gpg-agent (108 characters). Additionally, too many concurrent test calls
created IPC errors to gpg-agent. To get around this, tests were given
shorter names and refactored into subtests to create fewer concurrent
tests

Tested on Linux and MacOS.

32a16dcd8d pgp: check encryption keys before sending message
Add check for public keys of all message recipients (to, cc, and bcc)
before sending the message. Adds an OnFocusLost callback to header
editors to facilitate a callback for checking keys whenever a new
recipient is added (OnChange results in too many keyring checks).

Once encryption is initially set, the callbacks are registered. If a
public key is not available for any recipient, encryption is turned off.
However, notably, the callbacks are still registered meaning as s soon
as the user removes the recipients with missing keys, encryption is
turned back on.

5c5158b3c1 store: remove callbacks on error
Unmark deleted messages and remove pending headers in the callback
function when an error in the backend occurs (e.g. due to connection
issues).

The message store marks messages that should be deleted. If the delete
operation in the backend fails, messages are never unmarked and will
remain rendered as empty lines in the message list. This also affects
the move and archive commands that rely on a copy and delete operation.

A similar issue occurs with the pending headers when the operation to
fetch them fails. In this case, messages will appear as loading
indefinitely in the message list and are never re-fetched because the
corresponding pending headers from the failed operations are still
present.

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

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.

Keep the sort criteria applied to the selected folder until the default

The current behavior is that the default sort order is restored as soon

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.

The archive command will return an error to the ui when a nil message is

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".

69d4e3895f pgp: PGP/MIME signing for outgoing emails
implements PGP/MIME signing with go-pgpmail. The Sign() function of
go-pgpmail requires a private (signing) key. The signing key which matches
the senders email address (from field in email header) is looked up
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.

For this, we need to get rid of the distinction between a mailbox and a host

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.

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.
