This patch provides a method to report backend capabilities to the UI.
The intial capabilities included in the report are Sort and Thread.
Having these available to the UI enables the client to better handle
server side threading.

The maildir worker was adding Recent messages to the counts of Unseen
and Exists, however these messages were already included in those counts.

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.

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

Fix a data race due dirInfo pointer being read in the main goroutine
by NewMessageStore and written in the anonymous goroutine launched in
Worker.getDirectoryInfo.
To address the issue raised in https://todo.sr.ht/~rjarry/aerc/16, we
use readdir(3) once, parse and cache its results, this replaces
go-maildir library Dir.Flags based stat(3) and filepath.Glob
causing the issue when N (emails) is large.

Since commit 01c96e78df ("Update DirectoryInfo handling for maildir"),
flags are checked for every message of a folder when entering it.
Iterating over all messages of a folder takes a long time for large
collections of emails.
Only count the number of messages and state that the directory info
counts are not accurate. Defer the parsing of message flags in
a goroutine to have a more responsive UI.

Signed-off-by: Nguyễn Gia Phong <mcsinyx@disroot.org>
Previously, Message.NewReader returned the wrapped buffered reader
without a reference to the opened file, so the files descriptors
were left unclosed after reading. Now, the file reader is returned
directly and closed on the call site. Buffering is not needed here
because it is an implementation detail of go-message.

Messages flags can also be changed without changing directories.
Changing flags in maildirs means renaming the message files. Also take
renames into account.

When a maildir is synchronized by an external process while aerc is
running (e.g. mbsync), some emails may be moved out of "new" to "cur" or
completely deleted.
These deletions are ignored and aerc may assume these messages are still
here, leading to errors.
Take file deletions into account. Also, add "cur" to the watched
folders since these can be modified as well.

In the maildir worker we manually need to track the Recent flag in order for the
notification command etc to work.
Push that responsibility to the container, we must make sure to manually add the
flag though if one grabs the message info.
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.
If accounts.conf contains an invalid maildir url, return a nice
error instead of panicking.
Log a couple of different error cases to provide extra
information about the error to the user.
Aerc usually used the path []int{1} if it didn't know what the proper path is.
However this only works for multipart messages and breaks if it isn't one.
This patch removes all the hard coding and extracts the necessary helpers to lib.
Provide search and filter with the option to specify more flag based
conditions.
Use '-x <flag>' to search for messages with a flag (seen, answered,
flagged) and '-X <flag>' to search for messages without a flag.
More mail flags can now be set, unset, and toggled, not just the
read/seen flag.
This functionality is implemented with a new `:flag` and `:unflag`
command, which are extensions to the matching `:read` and `:unread`
commands, adding support for different flags. In fact, the
`read`/`unread` commands are now recognized aliases to `flag`/`unflag`.
The new commands are also well documented in aerc(1).
The change mostly extends the previous read/unread setting functionality
by adding a selection for the flag to change.
- Add maildir flags to complement a messages imap flags
- Set the "seen" flag on sent messages when using the maildir backend
- Cleanup AppendMessage interface to use models.Flag for both IMAP and
maildir
This ensures that the directory info is up to date on events in the
maildir worker. This also sets up the initial dirinfo for other
directories and updates them when using built-in commands.
FS events are still only watched for the selected directory. This should
be changed in a future patch to watch other directories too in order to
cover UI updates for folders when an event occurs in a non-selected
folder.
This changes the search flags for maildir and imap backends.
They now no longer use -t for searching all text. This seems to make
more sense as being the targeted recipient. I have similarly added Cc
for -c. The text search now resides under -a for all text.
There is a command and config option. The criteria are a list of the
sort criterion and each can be individually reversed.
This only includes support for sorting in the maildir backend currently.
The other backends are not supported in this patch.
This populates the directory info model properly when requested,
allowing the fields to be relied upon elsewhere.
This also sends the dirinfo when new messages come in.
Basic searching is supported with the following:
- read messages
- unread messages
- from addresses
- text in body
- text in subject
- text in all
The implementation loops through all messages in the selected directory.
It tries to be smart by detecting which parts of each message the search
query needs to use and only loads these from the filesystem.
Things like FetchEntityPartReader etc can be reused by most workers
working with raw email files from disk (or any reader for that matter).
This patch extract that common functionality in a separate package.
When a directory is opened, start watching its "new" subdirectory for
incoming messages using the fsnotify library. When creation events are
detected, run the Unseen routine to move the message from new to cur and
add new UIDs to the store, updating the UI's list of directory contents
as we go.
Email headers can be encoded with different charsets, which is signalled
using a special character sequence. The go-message package provides two
different methods for accessing header values, Get(key) (actually
inherited from the embedded textproto.Header) which returns the raw
header value and Text(key), which returns the header's value decoded as
UTF-8.
Before, in the maildir backend, we were using the Get method which
sometimes resulted in encoded headers being displayed in the UI. This
patch replaces the incorrect usage of Get() with Text().
Add the initial implementation of a backend for Maildir accounts. Much
of the functionality required is implemented in the go-message and
go-maildir libraries, so we use them as much as possible.
The maildir worker hooks into a new maildir:// URL scheme in the
accounts.conf file which points to a container of several maildir
directories. From there, the OpenDirectory, FetchDirectoryContents, etc
messages work on subdirectories. This is implemented as a Container
struct which handles mapping between the symbolic email folder names and
UIDs to the concrete directories and file names.
