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.

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.

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.

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)

Debounce client-side thread building in the message store. Debouncing is
useful when multiple messages are loaded, i.e. when scrolling with

Without the debouncing, all client-side threads will be built everytime

message list ui when client-side threading is activated.
The default debouncing delay can be changed by changing
'client-threads-delay' in the UI config section.

This patch adds a config option to force the use of client side threads.
This option will override a servers Thread capability, and only build
threads on the client. It can be enabled contextually. For example:
[ui]
threading-enabled = true
[ui:folder~^Archive]
force-client-threads = true
This config would enable threads for all views, and use client threads
for folders that start with Archive. This can be advantageous if, for
example, the folder is very large and the server has a slow response due
to building threads for the entire mailbox
