When errors occur during a fetch header request, the requested headers
are deleted from pending and no information is given to the UI. Spinners
keep spinning, and ultimately as the view is refreshed, the headers are

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:

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.

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.
