The Invalidatable struct is designed so that a widget can have a
callback function ran when it is Invalidated. This is used to cascade up
the widget tree, marking things as Invalid along the way so that only
Invalid widgets are drawn. However, this is only implemented at the grid
cell level for checks if the cell is invalidated -- and the grid cells
are never set back to a "valid" state. The effect of this is that no
matter what is invalidated, the entire UI gets drawn again.
The calling through the Invalidate callbacks creates *several* race
conditions, as Invalidate is called from several different goroutines,
and many widgets call invalidate on their parent or children.
Tcell has optimizations to only rerender screen cells that have changed
their rune and style. The only performance penalty by redrawing the
entire screen for aerc is the operations *within the aerc draw methods*.
Most of these are not expensive and have relatively no impact on
performance.
Skip all of the OnInvalidates, and directly invalidate the UI when
DoInvalidate is called by a widget. This reduces data races, and
simplifies the widget redraw logic signficantly.

Add XOAUTH2 authentication support for IMAP and SMTP. Although XOAUTH2
is now deprecated in favor of OAuthBearer, it is the only way to connect
to Office365 since Basic Auth is now completely removed.
Since XOAUTH2 is very similar to OAuthBearer and uses the same
configuration parameters, this is basically a copy-paste of the existing
OAuthBearer code.
However, XOAUTH2 support was removed from go-sasl library, so this
change reimports the code that was removed from go-sasl and offers it
a new home in lib/xoauth2.go. Hopefully it shouldn't be too hard to
maintain, being less than 50 SLOC.

Instead of xdg-open (or open on MacOS), allow forcing a program to open
a message part. The program is determined in that order of priority:
1) If :open has arguments, they will be used as command to open the
attachment. If the arguments contain the {} placeholder, the
temporary file will be substituted, otherwise the file path is added
at the end of the arguments.
2) If a command is specified in the [openers] section of aerc.conf for
the part MIME type, then it is used with the same rules of {}
substitution.
3) Finally, fallback to xdg-open/open with the file path as argument.

When cached headers are fetched, an action is posted back to the Worker
to immediately fetch the flags for the message from the server (we can't
know the flags state, therefore it's not cached). When scrolling, a lag
occurs when loading cached headers because the n+1 message has to wait
for the flag request to return before the cached headers are retrieved.
Collect the message UIDs in the UI that need flags, and fetch them based
off a debounce timer in a single request. Post the action from the UI to
eliminate an (ugly) go routine in the worker.

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

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.

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)
