Introduce AercFuncMsg and QueueFunc. These are used in combination to
queue a function to be run in the main goroutine. This can be used to
prevent data races in delayed function calls (ie from debounce
functions).

Now that tcell events are handled in a goroutine, no need for a channel
to buffer them.
Rename ui.Tick() to ui.Render() and ui.Run() to ui.ProcessEvents() to
better reflect what these functions do.
Move screen.PollEvent() into ui.ProcessEvents(). Register the panic
handler in ui.ProcessEvents().
Remove aerc.ui.Tick() from DecryptKeys(). What the hell was that?

The UI runs off a 16 ms ticker. If no render is required, and no event
is seen, aerc waits 16 ms before checking for new events or render
requests. This severely limits handling of events from tcell, and is
particularly noticeable on pasting of large quantities of text.
Process tcell events in a separate go routine from the render loop.

Due to multiple levels of nested quoting, it is not possible to escape
spaces and/or quotes from GOFLAGS and pass the value to go build
-ldflags to set a compile time variable.
Encode main.Flags in base64 and decode it when reading it.

Do not pass logger objects around anymore. Shuffle some messages to make
them consistent with the new logging API. Avoid using %v when a more
specific verb exists for the argument types.
The loggers are completely disabled (i.e. Sprintf is not even called)
by default. They are only enabled when redirecting stdout to a file.

Use Aerc as an mbox viewer. Open an mbox file from the command line in a
new tab with the mbox backend. Provide a convenient and quick way to
display emails from an mbox.
Usage: aerc mbox://<path>
where the path can either be a directory or an mbox file. If it is a
directory, every file with an .mbox suffix will be loaded as a folder.
The account config will be copied from the selected account. This allows
the answer emails in the mbox account.

If a panic occurs in one of the workers, it can happen after the UI was
initialised, but before the cleanup function has been registered. With
this the start of the worker loops is deferred until the cleanup routine
was registered.

Since panics still regularly "destroy" the terminal, it is hard to get a
stack trace for panics you do not anticipate. This commit adds a panic
handler that automatically creates a logfile inside the current working
directory.
It has to be added to every goroutine that is started and will repair
the terminal on a panic.

Instead of using a static SHAREDIR at compile time, use a list of
standard paths to use at runtime for templates, config files and
stylesets.
This implies removing all default filters in the default configuration.

When provided with a mailto argument, aerc tries to connect to an
existing instance via a unix socket. If that fails, it starts up a new
instance and tries again. However, if that fails again (e.g. if the
unix server could not be started) then the new instance will remain open
without any indication that an error occured. Instead, shutdown the new
instance so the user can see the error message.
After commit 175d0ef ("binds: add account specific bindings"), when
bindings are defined for an account not defined in accounts.conf, aerc
quits with an error. After this commit, a warning is logged and aerc
ignores those bindings.

As of now we crash fairly often. The problem is that we didn't run the cleanup
routine of the ui in this case, leaving the pty in a bad state.
Instead, recover from a panic and at least try to run the ui deinit.
Previously the completions weren't sorted which led to a difficult to
navigate list, especially for the command names as it would randomly
jump through the alphabet.
Aerc tries to open mailto:// links via the socket of the already running aerc
instance.
If no socket exists this silently errored out.
This commit starts up a new aerc instance if it can't connect to the socket
(which I think is the most common error) and if not sets up a new aerc instance
and retries to open the compositor.
This fixes https://todo.sr.ht/~sircmpwn/aerc2/295 by implementing the desired
behaviour.
We need some way to signal the backends that we are about to shutdown,
allowing them to clean up (for example in notmuch committing the db changes).
This commit implements a hook which gets called upon shutdown, providing
backends implement the io.Closer interface.
Currently we /dev/null stdout, if it is a tty.
The checkConfigPerms function, as well as the error print were incorrectly
writing to stdout and therefore weren't visible to most users.
Aerc will keep track of the previous 1000 commands, which the user can
cycle through using the arrow keys while in the ex-line. Pressing up
will move backwards in history while pressing down will move forward.
This patch sets up the trigger config section of aerc.conf.
Each trigger has its own function which is called from the place where
it is triggered. Currently only the new-email trigger is implemented.
The triggers make use of format strings. For instance, in the new-email
trigger this allows the user to select the trigger command and also the
information extracted from the command and placed into their command.
To actually execute the trigger commands the keypresses are simulated.
Further triggers can be implemented in the future.
Formatting of the command is moved to a new package.
There is a LoadConf and a LoadConfFromFile.
LoadConfFromFile reads the iniFile into memory and and calls
LoadConf, which executes the old parsing commands from
LoadConf (old func).
The remaining of the LoadConfFromFile is the same as the old OldConf.
Consists of 3 functions
* Store: Access to MessageStore type
* SelectedAccount: Access to Account widget that the target widget
belongs to
* SelectedMessage: Current message (selected in msglist or the one we
are viewing)

This commit introduces a new Aerc.Tick function that should be called to
refresh the internal state. This in turn makes each AccountView process worker
events.
The UI goroutine repeatedly refreshes the internal state before drawing a new
frame. The reason for this is that many worker messages may need to be
processed for a single frame, and drawing the UI is far slower than refreshing
the internal state. This has been confirmed in my testing (calling Aerc.Tick
only once per frame results in a slower display).
Many synchronization code has been removed. We can now write widgets without
having to care so much about races. The remaining sync users are:
- widgets/spinner: the spinner value is updated from inside an internal
goroutine
- lib/ui/invalidatable: Invalidate may be called from any goroutine
- lib/ui/grid: same
- lib/ui/ui: an internal goroutine needs read access to UI.exit
- worker/types/worker: Worker.callbacks is used for both worker and UI
callbacks
The exact goroutine requirements for Drawable have been documented.
