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.

Commit 2027223a created a panic when attempting to clear the dirlist
when the config option dirlist-tree is set to false.
This patch fixes that panic by creating a dirlist.ClearList() function
to prevent needing to check a callback.
Tested with both dirlist-tree=false and true

A message of Done:Disconnect will trigger an update of the dirlist. An
update of the dirlist will issue a ListDirectories message, which causes
an imap: client not ready error by trying to use the imap connection -
which is disconnected. By not issuing the update, we prevent using a
disconnected client.
This patch checks for connection state prior to updating the dirlist. A
disconnected state will clear out the dirlist.

If an error occurs when parsing the content-type, check if the
content-type is quoted; if so, remove quotes. If this is not the case,
then return a text/plain content-type as a sane fallback option, so that

When moving/copying/deleting/archiving a message in imap, the RUE counts
displayed in the dirlist would not update properly. Maildir has (had) an
implementation that recounts the entire directory and updates the
DirectoryInfo after one of these actions.
This patch implements a more efficient method of updating, and also
enables it to apply to IMAP without any additional requests. Upon
completion of the action, the counts are manually updated with the count
of messages in the action and recent and/or unseen states of those
messages. This is more efficient for maildir, because we aren't counting
everything in the store. For IMAP, we get the updates for free because
we are only performing the update after confirmation from the server
that the action has happened.

The countRUE function was inaccurately counting flags. If a message was
unread and recent, it was only counted as recent. The two flags are not
mutually exclusive. A previous count for a mailbox with 1 recent, 1
unread, and 5 existing would be :
1/0/5
An accurate count of this state would be:
1/1/5
This patch fixes the count.

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

Commit 1bac87e80414 ("terminal: fix race when closing a terminal") fixed
a race in Terminal.Draw by using a mutex. The current locking of the
entire Draw function could create a deadlock, however, since this
function itself might call Terminal.Close which is protected by the same
mutex. A finer-grained locking solves both the race and deadlock
problem.

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.

Fix race when closing a terminal. The race appears as a nil pointer
dereference panic in pty.StartWithAttrs when trying to access the
provided term.cmd variable.
Before calling pty.StartwithAttrs in the Terminal.Draw function,
term.cmd is checked for nil. Terminal.Close must be called concurrently
right after this check and before/while entering pty.StartWithAttrs.
This can be avoided with a mutex.

Fix panic when resizing the terminal by dynamically adjusting the width
of the option selector. The selector does not check the width of the
terminal before printing. This can lead to a panic in the account wizard
when reducing the terminal width.
If the terminal width is not large enough, the space between the options
is reduced. If this is still not enough, then the selector will only
show the focused option and arrows indicating the alternatives.

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.

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.

This happens because the flags are updated in the callback that receives
the message itself. It causes the flag update to arrive in the same
channel/request. Ignore the messages that have an empty body (i.e. only

to get rid of these extra messages.

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.
