Tim Culverhouse 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.

Tim Culverhouse 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.

Koni Marti 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.

Tim Culverhouse 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.

Koni Marti 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.

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.

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

Koni Marti 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".

y0ast dc2a2c2dfd messages: allow displaying email threads
Display threads in the message list. For now, only supported by the
notmuch backend and on IMAP when the server supports the THREAD
extension.

Setting threading-enable=true is global and will cause the message list
to be empty with maildir:// accounts.

Robin Jarry 074b0a1bd8 view,list: fix crash when viewing incomplete imap messages
With IMAP, due to an unidentified reason, some messages to not have any

  dereference

Check the pointer before dereferencing.

Also, add a global check in ParseMessageFormat where a similar issue may
occur.

Robin Jarry fc84b19bba view,compose: use border color to separate headers from body
When composing a message, there is an empty fill line between the
headers and the text editor. The line is printed with the default style
which may cause users to assume it is part of the editor.

Display the fill lines with the border color to avoid confusion.
