WindowServer: Skip blitting windows into the back buffer if possible.
...
Windows that don't intersect any of the dirty rects don't need to be copied
into the back buffer since they won't be affected by the subsequent flushes.

Allow the scheduler to unblock the current process.
...
It's a bit confusing that the "current" process is not actually running
while we're inside the scheduler. Perhaps the scheduler should redirect
"current" to its own dummy Process. I'm not sure.
Regardless, this patch improves responsiveness by allowing the scheduler
to unblock a process right after it calls select() in case it already has
a pending wakeup request.

Tear out or duplicate what's unique for WindowServer from Widgets.
...
This turned into a huge refactoring that somehow also includes
making locks recursive/reentrant.
