f414db7858 terminal: protect calls to terminal methods throughout aerc
A race condition can occur when a PartViewer is closing and also working
on a draw. The closing process sets the terminal to nil, which will
create a panic. This can be tested in development by setting the timer
in the main aerc tick loop to something very low (1 ms for example).

One other unprotected call to terminal exists in the composer widget.

Check that the terminal is not nil before calling methods on it.

77f69501d6 msgviewer: properly close embedded terminal
The terminal widget already handles most boring stuff: unwatch terminal
events, kill the underlying process, wait for it to exit, etc. Call the
Close() method and be done with it.

This avoids issues where the embedded terminal widget is destroyed but
the pager process does not know about it and dies in agony, writing over
aerc's UI:

  Vim: Caught deadly signal HUP

Also, it may avoid leaving child processes as zombies without giving
them a proper burial.

518f3e962c term: replace go-libvterm with tcell-term
Replace go-libvterm package with tcell-term. go-libvterm provides the
embedded terminal for aerc. It uses a statically linked C library,
requiring CGO.

tcell-term is written in pure go and is written to be portable with
tcell applications by implementing the tcell Widget interface. This
allows the terminal to take a view (which aerc already supplies) and
draw directly to it, as well as issue tcell Events to a Watcher.

Enable setting cursor shapes in embedded terminals.

Losing your progress in case of a crash, or when accidentally closing
aerc is annoying and costs time. This can be drastically reduced by

c947811e9f ui: process tcell events in a separate go routine from rendering
The UI runs off a 16 ms ticker. If no render is required, and no event
is seen, aerc waits 16 ms before checking for new events or render
requests. This severely limits handling of events from tcell, and is
particularly noticeable on pasting of large quantities of text.

Process tcell events in a separate go routine from the render loop.

fad90c2956 open-link: make URL parsing more lenient
URLs are extremely loosely defined and can take many shapes which may
not be parsed at all if unusual characters like the exclamation mark are
present. To ensure lists and odd use of spaces are not parsed as links
some sanity-checks are in place:
	- the URL's schema must be at least two characters long
	- the URL's authority, path, and fragment must have a combined
	  length of 8 characters or longer
	- the URL must not contain a whitespace character, >, ), or "
	- the URL may only contain a ] when followed by a different allowed
	  character or at the end of the line (necessary for IPv6
	  authorities)

The tests for this function now include links with an exclamation point
and IPv6 addresses. The tests are given names to be easier identifiable.

abf6ec7f02 config: keep cache of resolved credential commands
outgoing-cred-cmd is used to retrieve the password from a password
manager such as UNIX pass or bitwarden CLI. These tools often prompt for
a passphrase to secure the passwords and it is annoying having to enter
it every time sending an email with aerc.

Add a new option outgoing-cred-cmd-cache (default to true) to control
whether aerc will keep a cache of the password or run outgoing-cred-cmd
every time an email needs to be sent.

NB: If the cached password is incorrect, the only way to change it is to
restart aerc.

380cf13cff msgstore: run threadBuilder with no debounce on DirectoryContents msg
Commit 54a0a377e0 ("threads: debounce client-side thread building")
introduced the option to debounce threadbuilding to improve performance
of client side threads. This caused a UI regression during filtering of
mailboxes:

1. The mailbox contains the full set of message UIDs
2. User filters mailbox
3. A DirectoryContents message is received from worker with the proper
   UIDs to display
4. Debounce is started (in a separate go routine)
5. The value of msgStore.Uids() is used to show pending headers, but is
   not updated until the threadbuilder runs. The full set of UIDs is
   shown briefly
6. Debounce is over, threadbuilder runs, updates msgStore.Uids(), proper
   messages show.

Run the thread builder immediately upon receipt of a DirectoryContents
message, bypassing any debounce. Performance will remain the same: the
debounce is meant to prevent multiple sequential calls to the thread
builder during scrolling. This is unlikely to occur in rapid succession
from filtering or sorting.

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.

5ed849688a parse: remove trailing whitespace from rfc1123z regex
When there is no Date header in a message, aerc falls back to the
Received header and tries to extract an rfc1123z date from it
(introduced in commit d1600e46). The current regex for extracting the
date incorrectly allows for trailing whitespace, causing time.Parse() to
fail inside of parseReceivedHeader(). As a result, the message's date is
shown as "???????????????????" in the message list and as
"0000-12-31 07:03 PM" in the message view (the latter is likely related
to the zero value of time.Time).

Steps to reproduce:
1) Send yourself a message with no Date header, e.g. with msmtp:
printf 'Subject: foo bar\n\nbody text\n' | msmtp --set-date-header=off me@example.com
2) Note the message's displayed date in aerc's message list and message
   view.

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.

Fixes the find-next-loop when deleting the last message. The reverse
loop with store.Prev() will break too early because the value of
'previous' was not reset correctly.

588be1a284 store: improve cursor position
Improve cursor re-positioning while filtering with and without threads.
Reposition cursor in client-side threading mode with a callback that is
set during store.NextPrev(). Run callback when the threads are
constructed in order to reposition the cursor correctly. The callback is
deactivated when store.Select() is called.

Steps to reproduce two issues:

* Reproduce issue 1:

1. Activate client-side threading
2. Apply a filter, e.g. :filter -f Koni
3. Move cursor around so that a message is highlighted
4. clear filter with :clear
5. The cursor is expected to remain on the selected message but is
   actually not

* Reproduce issue 2:

1. Activate client-side threading
2. Go the end of the message list
2. Apply a filter, e.g. :filter -f Koni
5. The cursor is now at the end of the filtered results instead of at
   the beginning

This patch fixes both of those issues. Tested in regular and threaded
view according to the following check list (expected behavior in
parenthesis):

1. Apply filter from a message that remains in the filter (cursor on message,
   message selected)
2. Apply filter from a message that will not remain (cursor at the top,
   no message selected)
3. Clear filter (cursor remains on message, message selected)
4. Scroll line-by-line (threads: cursor remains on line, does not "jump"
   with message)
5. Search (cursor on first result)
