Set CRTC state correctly after waking up. Otherwise the displays will keep
their previous state until the next redraw.

Use the new UI subsystem in the main application. The kmscon application
provides now the same functionality as the test_terminal application.

The hook structure can be used to provide a central hook where other
subsystems can register callbacks.

We cannot check for dev->fd as the fd is only set when the input device
has keys. Therefore check for rfd now.
Also remove the NULL check in *_sleep() as it is not needed. All public
APIs allow passing NULL.

Remove newline from log-messages and set LOG_SUBSYSTEM to "input". Also
fix some small indentation issues.

Suppress debug, info, notice and warning messages if --silent is given.
This is overwritten by --debug and --verbose.

eloop.c and log.c use struct timeval to calculate time-diffs but
incorrectly use "-" instead of "+" as the value is already negative.
They also use unsigned integers so fix both occurences.

When exiting a child eloop we should forward the exit to the parent. Also,
we should reset ->exit on ev_eloop_run() otherwise we cannot run multiple
times.

--switchvt enables kmscon to automatically switch to the new VT that was
opened by kmscon. If this is the current VT, then this has obviously no
effect.

ev_eloop_run() runs the eloop for a given fixed time. If the dispatcher
returns and the timeout isn't reached, then the dispatcher is called
again.
This also adds the *_exit() function which allows to exit the main-loop
and can be called from anywhere (including the callbacks).

If a handler does not correctly remove itself on HUP, the epoll-loop will
never sleep again because the fd will always be notified as HUP.
Therefore, remove the fd from the epoll-set directly on HUP. This doesn't
change application behavior so it is safe here.
This also allows other subsystems to ignore HUP/ERR events if they are not
fatal. The FD won't be readded but that may not bother.

The conf-subsystem is used throughout the whole source and provides a
global static read-only configuration. The configuration is read on
startup from the command-line and filesystem and then provided to the
other subsystems.
This is no database, that is, the data is not written to a file on
shutdown!

This allows to add one eloop object into another eloop. This is useful if
we want to run a single event source isolated (for instance VT on exit).
The internal epoll-descriptor allows polling so this is a fairly
straightforward implementation.

We currently have too much layers in the console subsystem. This reduces
performance and produces ugly hacks like our "*_clear_region" function. We
now merge both files so we can directly access the buffer-structure.

Inside a screen object we are independent of the lifetime of the displays
so we need to correctly keep references to them.
