e7a51f5524 backends: send MessageInfoError on header fetching error
When an error is encountered fetching a header, the backends respond
with a type.Error worker message. On receipt of this message, the UI
deletes all pending headers. The headers are all requested again as they
remain on the screen, resulting in an infinite request loop - and an
infinite logging loop. The user only ever sees the spinner unless they
check the logs.

A previous commit intended to fix this, however it introduced a
regression where any message that was part of the fetch request would
also be marked as erroneous. This commit is reverted with commit
2aad2fea7d36 ("msgstore: revert 9fdc7acf5b48").

Send an erroneous message info message from the backend when an error is
encountered for a specific UID.

921382a9bf maildir: do not send dircontents on fs event
The maildir worker watches the file system for events (new mail, moved
mail, copied mail, etc). On an event, the worker sends a
DirectoryContents message and a DirectoryInfo message.

Do not send DirectoryContents on FS Event in the maildir worker. The
DirectoryInfo message already triggers the UI to request the new
DirectoryContents, and does so in a more predictable way (IE any
currently applied filter is applied).

1c9fc7b6b1 maildir: remove filename encoded UID when moving messages
The built-in maildir.Dir.Move method performs an OS level file rename,
which allows for preserving file creation time. Commit c98f704874
("move: enable MoveMessages from msgstore") enabled the use of the Move
method for maildir. One particular maildir synchronizer (isync/mbsync)
encodes the UID within the filename of the email and cannot recover if
the UID is preserved during a move. mbsync encodes filenames like so:

	/path/to/email/{maildir-key},U={uid}:2,S

OfflineIMAP encodes the UID within the filename, but also encodes a hash
of the originating folder so that it can recover from a move without a
rename of the underlying file. OfflineIMAP encodes like so:

	/path/to/email{maildir-key},U={uid},FMD5={folder-hash}:2,S

Remove encoded UIDs of the form `,U={uid}` from filenames to prevent
sync issues.

af72ca3607 maildir: implement MoveMessages handling
Implement MoveMessages in the maildir worker. go-maildir supports Move
operations by default, and is functionally equivalent to a OS-level
rename. Creation date of the file is preserved by using Move, which is
used by at least one maildir-to-IMAP synchronizer (isync/mbsync). The
previous move method of copy-and-delete would reset the creation date of
the message, and potentially cause sorting issues in other email
clients.

c2f4404fca threading: enable filtering of server-side threads
This patch enables the filtering of a threaded view which uses
server-built threads. Filtering is done server-side, in order to
preserve the use of server-built threads.

In adding this feature, the filtering of notmuch folders was brought up
to feature parity with the other workers. The filters function the same
(ie: they can be stacked). The notmuch filters, however, still use
notmuch syntax for the filtering.

8b6f9719a8 dirlist: update RUE counts for imap/maildir on move|copy|delete|archive
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.

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

go-maildir library Dir.Flags based  stat(3) and filepath.Glob

counts are not accurate. Defer the parsing of message flags in

1687e558d3 notmuch/maildir: remove double emit of the dirinfo
There was some bug which could be worked around by double emitting an event.
However that proofed to be brittle:

We send the first message here from the worker goroutine:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/maildir/worker.g=
o#L306

Then Tick() is waked in the main goroutine and calls ProcessMessage:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/widgets/account.go#L100

ProcessMessage in the main goroutine reads types.Message state with
msg.getId() and msg.InResponseTo():
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/types/worker.go#=
L74-76

Meanwhile in the worker goroutine we call PostMessage for a second
time with a pointer that points to the *same* previous message that
ProcessMessage is reading:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/maildir/worker.g=
o#L306

The second PostMessage call makes writes to message while
ProcessMessage in the main goroutine is possibly reading:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/types/worker.go#=
L59

This led to a data race in the event loop

fe1cabb077 Add support for :rmdir
The `:rmdir` command removes the current directory (`-f` is required if
the directory is not empty).

This is not supported on the notmuch backend.

An issue with the maildir backend is that some sync programs (e.g.
offlineimap) may recover the directory after it is deleted.  They need
to specifically be configured to accept deletions, or special commands
need to be executed (e.g. `offlineimap --delete-folder`) to properly
delete folders.

A danger of using this on the IMAP backend is that it is possible for a
new message to be added to the directory and for aerc to not show it
immediately (due to a slow connection) - using `:rmdir` at this moment
(with `-f` if the directory already contains messages) would delete the
directory and the new message that just arrived (and all other
contents).  This is documented in aerc(1) so that users are aware of
possible risks.
