Select the first message with NextPrev when the cursor disappears after
applying a filter where the selected message is not part of. Currently,
the NextPrev would select the last message in the mailbox (like a G
jump).
To reproduce:
1) select a message
2) apply a filter where the selected message is not selected
3) move the cursor and it will jump to the last message

Debounce client-side thread building in the message store. Debouncing is
useful when multiple messages are loaded, i.e. when scrolling with
PgUp/PgDown.
Without the debouncing, all client-side threads will be built everytime
the message store is updated which creates a noticable lag in the
message list ui when client-side threading is activated.
The default debouncing delay can be changed by changing
'client-threads-delay' in the UI config section.

Commit 3a614e45fc ("threading: enable toggle-threads for server-side
threads") changed the behavior of the msgstore.buildThreads variable to
reflect whether the client needs to build threads or the server will.
However, a call to runThreadbuilder was not updated with an extra
conditional. As a result, threads were built regardless of the state of
the threadedView resulting in a large performance penalty for
non-threaded views with client side threading.
Only run thread builder if threaded view is enabled.

This patch adds a config option to force the use of client side threads.
This option will override a servers Thread capability, and only build
threads on the client. It can be enabled contextually. For example:
[ui]
threading-enabled = true
[ui:folder~^Archive]
force-client-threads = true
This config would enable threads for all views, and use client threads
for folders that start with Archive. This can be advantageous if, for
example, the folder is very large and the server has a slow response due
to building threads for the entire mailbox

In order to better align to vim functionality: deselect visual mode
selections after performing a command on the selection. This patch also
introduces a new command to allow for re-selecting (remarking) the
previous selection set so that commands can be chained together. The
deselection only applies to msg commands that *do not* move the message
from the store (those types of commands already deselect):
- read/unread
- flag/unflag
- modify-labels
- copy
- pipe
Previous usage to mark several messages as read and deselect all:
Vjjj:read<Enter>:unmark -a<Enter>
New usage, similar to vim:
Vjjj:read<Enter>
To chain a command together:

Unmark deleted messages and remove pending headers in the callback
function when an error in the backend occurs (e.g. due to connection
issues).
The message store marks messages that should be deleted. If the delete
operation in the backend fails, messages are never unmarked and will
remain rendered as empty lines in the message list. This also affects
the move and archive commands that rely on a copy and delete operation.
A similar issue occurs with the pending headers when the operation to
fetch them fails. In this case, messages will appear as loading
indefinitely in the message list and are never re-fetched because the
corresponding pending headers from the failed operations are still
present.

Fix the "no envelope available for this message" error that can occur
when using the same imap mailbox in another mailclient (e.g.
through a webmail interface) at the same time.
Complements the fixes in commit 7fe7fe4 ("ui: fix panic in header
formatter") and commit 074b0a1 ("view,list: fix crash when viewing
incomplete imap messages").
The error is caused when a message attribute update is received by the
message store before the message list had a chance to fetch the proper
header first. In this case, an (incomplete) message info is stored in
the message store and the message list will never fetch the correct
header. To prevent this, add only messages to the store with a non-nil
envelope but make sure that message attribute updates are properly
merged.

Keep the sort criteria applied to the selected folder until the default

to restore the default sort order.
The current behavior is that the default sort order is restored as soon
as the folder reloads. This happens often and then the results of the
sort command are lost. This makes the sort command not very
user-friendly. Instead, we should keep the sort criteria applied until
the user explicitly wants to restore the default sort order again.

Update message counter in msglist when the filter is changed (either set or
cleared in the msgstore).
When we apply a filter, we change the number of uids in the message
store. This can unintentionally trigger the storeUpdate() function of
the msglist which checks the number of uids for new messages and
advances the pointer by the difference in the number of messages. This
can be avoided when we update the message counter upon changing the
filter.

More mail flags can now be set, unset, and toggled, not just the
read/seen flag.
This functionality is implemented with a new `:flag` and `:unflag`
command, which are extensions to the matching `:read` and `:unread`
commands, adding support for different flags. In fact, the
`read`/`unread` commands are now recognized aliases to `flag`/`unflag`.
The new commands are also well documented in aerc(1).
The change mostly extends the previous read/unread setting functionality
by adding a selection for the flag to change.
This changes the ui to show the spinner while we are sorting. It only
shows one line of the spinner since there are an unknown number of
messages at this time.
Apparently sending an event for every incoming messageInfo slows down
the application significantly.
Therefore this slows down the emmision rate, on the cost of being out of date
in some cases.
This reverts commit bd4df53009.
I did not properly untangle the opening / dirlist update of each other.
This interferes with the imap worker, hence the revert
Actions such as read / unread or the addition of new messages do change
the read/unread/recent count. Hence we request an update from the workers.
Workers going over the network should probably cache the information and invalidate
it only if necessary
Previously, sending a DirectoryInfo assumed that a directory change
happened. However we don't want that if we only want to update the
unread message count.
