Upgrade tcell-term to v0.2.0
Use Start method from tcell-term. This prevents aerc from needing to
wait until the command has started to continue. The tcell-term start
method blocks until the command is started, similar to cmd.Start. By
doing so, we prevent a race condition between aerc and tcell-term on
access to cmd.Process.
Remove cleanup of cmd, this is all already handled by tcell-term when
Close is called.

Moves logic for creating dynamic folders from the dirlist widget to the
backend. Since dynamic folders are notmuch-specific, the notmuch backend
should be responsible for correctly setting up those folders. It does
that by sending two DirectoryInfos: the first to create the message
store, the second to fetch the directory content.
This approach also fixes a deadlock introduced by 716ade8968
("worker: lock access to callback maps").

The exline widget works by matching actual keystrokes to a map of
keybinds, and if a match is found sending simulated keystrokes through
aerc. This has the effect of aerc thinking we are actually typing in the
expanded command, and aerc attempts to draw the completions. This
results in even basic navigation having two screen draws:
For example, pressing 'j' to select the next message (:next), draws once
for the initial key event and state change, and again after the
completion debounce timer.
Disable tab completion while aerc is simulating keystrokes. If the
exline still has focus after simulating keystrokes, restore tab
completion.

The terminal widget uses it's own internal event handler to redraw
itself for improved performance. The event handler draws, updates the
screen, and invalidates. The last invalidate is redundant: Invalidating
has the result of telling aerc to redraw the screen. A race condition
can occur where an event is emitted from the terminal and the terminal
is closed before the event is handled. This results in handling the
event after the terminal is closed, and a panic:

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)
