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.

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

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 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

These backends do not return the full message body with CRLF

If this is not the case the signed and transmitted data are considered

Fix the "no envelope available for this message" error that can occur
when using the same imap mailbox in another mailclient (e.g.

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
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.

When we apply a filter, we change the number of uids in the message

advances the pointer by the difference in the number of messages. This

implements PGP/MIME encryption with go-pgpmail. The Encrypt() function of

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

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.
