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.

When errors occur during a fetch header request, the requested headers

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.

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)

With this applied, columns will still be misaligned a little only if

than a large offset caused by each wide characters in the column.
