f27db33305 worker/types/worker: make ID allocation atomic 
Message IDs are allocated for both messages from UI to workers and the other
way around. Hence, the global nextId variable is accessed from multiple
goroutines.

Instead, use atomic to access the global counter.

34dd6bc635 worker/types/worker: set ID before sending message 
The previous code set the message ID after sending it, which could result in
the receiver reading the ID before it's set.

7c6325977b lib/ui/ui: use atomic instead of channel 
This makes it so an atomic `invalid` value is used instead of an unbuffered
channel. When many invalidations kick in, a lot of values were sent to the
channel.

(Since OnInvalidate's callback can be run in any goroutine, we need to be
careful about races here.)

a15ea01cfb Update internal state and draw from the same goroutine 
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.

1da3239345 widgets/terminal: fix damage race condition 
Terminal.damage is accessed when drawing and when invalidating the widget. For
this reason we need to protect it with a mutex.

This seems to fix various damage issues I've been experiencing (where some
regions of the terminal weren't correctly repainted).

Race detector trace:
