We should activate the GL context on initialization to allow other subsystems to
create GL objects.

Currently, we set up our VT with SIGUSR1/2 signals and after that the user may
connect the signal handlers to the eloop. However, if we receive a signal in
between, the signal gets lost.
Therefore, this simply merges the kmscon_vt_connect_eloop function into
kmscon_vt_open as there is no obvious reason to split them.

We must not destroy the compositor object if there is still a console using the
GL context. Otherwise we get a SEGFAULT when calling any gl* function.
In future we may need propoper dependencies here. We use reference counts so
this should be easy to implement.

Remove the *_set_res() function entirely. Instead, the *_resize() function now
accepts a height argument which is used as quality hint. Internally, we compute
the texture width by the selected font plus the given height. This simplifies
the API and the internal handling and improves output on non-standard
resolutions or with non-standard fonts.
Until now it was only optimized for my 16x9 output but 5x4 output was quite
garbled.

Add kmscon_console_write() to write a character to the current position of the
cursor. The cursor is automatically moved to the next cell.
Also extend the test_console example to use this new function.

When resizing lines we shouldn't drop all information. Instead we only
initialize new cells.

This test app is used to stress test the buffer implementation and finding bugs
of the scrollback-buffer rotations etc.

Add two functions to enter/leave our VT object. This allows to
implement to expected behavior of automatically switching to the kmscon
when it is running on a new tty, and switching back to the tty we came
from when the program finishes. Presumably this behavior will be
controlled by a config variable or command line argument later on (like
Xorg's -novtswitch).
There's a bit of a subtlety in this because of VT_PROCESS. We need
permission from ourselves to switch in/out of out VT; this is done when
processing SIGUSR[12] in the eloop. We therefore must dispatch the loop
at least once after switching out. The usual case is demonstrated in
test_vt.c.

The test_console application now supports VT-switching and monitor-hotplug. New
monitors are detected when switching VTs. Full hotplug-support will be added
later.

Correctly handle SIGINT and SIGTERM. This will also reset the crtc so it won't
stay black if the application is killed.

This test application prints a console on all connected outputs. It does not
emulate any terminal but instead just prints the test-console.
It can be used to test the console subsystem in connection with the DRM/KMS
output subsystem.

Waking up the compositor automatically refreshed the output list. Therefore,
avoid refreshing it manually again.

The test_output application is an example how to use the output subsystem. It
lists all connected monitors/DRM-outputs and draws with OpenGL on the selected
framebuffers.
