The Tabs object exposes an array of Tab objects and the current selected
index in that array. The these two fields are sometimes modified in
goroutines, which can lead to data races causing fatal out of bounds
accesses on the tab array.
Hide these fields as private API. Expose only what needs to be seen from
the outside. This will prepare for protecting concurrent access with
a lock in the next commit.

When opening unread emails from certain people (I won't name any names,
sorry), an annoying error message is displayed on the status line:
could not get section &imap.BodySectionName{BodyPartName:
imap.BodyPartName{Specifier:"", Path:[]int(nil), Fields:[]string(nil),
NotFields:false}, Peek:false, Partial:[]int(nil), value}
This does not occur for already read messages. This issue is similar to
the one that was fixed in commit 8ed95b0d2a ("imap: avoid crash when
replying to unread message").
This happens because the flags are updated in the callback that receives
the message itself. It causes the flag update to arrive in the same
channel/request. Ignore the messages that have an empty body (i.e. only
containing flag updates). This is inherently racy but there seems no way
to get rid of these extra messages.

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.

Implement an mbox backend worker. Worker can be used for testing and
development by mocking a backend for the message store. Worker does not
modify the actual mbox file on disk; all operations are performed in
memory.
To use the mbox backend, create an mbox account in the accounts.conf
where the source uses the "mbox://" scheme, such as
source = mbox://~/mbox/
or
source = mbox://~/mbox/file.mbox
If the mbox source points to a directory, all files in this directory
with the .mbox suffix will be opened as folders.
If an outgoing smtp server is defined for the mbox account, replies can
be sent to emails that are stored in the mbox file.

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

GetUiConfig was being called many times, and came up as a high CPU user
in a cpuprofile. Every call would merge a UIConfig, which is a costly
operation. Ideally, we would only need to have a config for every
account X every directory. We also have a context for subjects. This
patch stores all FOLDER and ACCOUNT level configs and reuses those
merged objects. The SUBJECT contexts are not stored in favor of merging
on-the-go, with a TODO comment to deprecate that feature and implement a
better per-message styling option. I suspect this feature is not used
very much.
Before applying this patch with my setup, GetUiConfig is called 1159
times just to open aerc. After applying, this is reduced to 37.

The completion mechanism only provides completions when there is at least

The mechanism is based on other commands' completions and works as follows:
1. Attempts to look up a command by the name specified in args[1].
2.a On success it uses command.Complete.
2.b Otherwise, if total arguments count is lesser or equals than 2
(i.e. no command arguments specified), it attempts to complete
the command's name.
Additional effort is made to preserve prompt text, which often contains
