When an error is encountered fetching a header, the backends respond
with a type.Error worker message. On receipt of this message, the UI
deletes all pending headers. The headers are all requested again as they
remain on the screen, resulting in an infinite request loop - and an
infinite logging loop. The user only ever sees the spinner unless they
check the logs.
A previous commit intended to fix this, however it introduced a
regression where any message that was part of the fetch request would
also be marked as erroneous. This commit is reverted with commit
2aad2fea7d36 ("msgstore: revert 9fdc7acf5b48").
Send an erroneous message info message from the backend when an error is

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.

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.
