We use a new font factory which is used to create a new font. It will later also
be used to cache fonts and select proper system fonts.

Add input subsystem to terminal test app. This currently allows to actually
"write" to the console. There is still much to do to convert the input to proper
data but basic alphanumeric characters work for now.

Just a direct mapping to X modifiers for now (= Shift, Control,
Lock, Mod1-5).
This gives us more flexibility to adapt it to our needs in the future.
Also we don't have to include libxkbcommon headers just for the modifier
definitions.

This commit introduces a new kmscon_input_event structure which is
delivered to the input consumer. The information provided is
- The evdev scancode (=physical keyboard key).
- The X keysym (a symbol representing what the typist really intended).
- The active modifiers (e.g. Shift, Control..)
- The unicode (UCS-4) value, when it makes sense.
To achieve this we add two dependencies:
- libxkbcommon (this entails xproto and kbproto, but shouldn't bring any of
big X dependencies)
- A function to translate keysyms to unicode values (taken from xlib,
copied in-tree).
libxkbcommon is not an all-around solution, and requires various degrees
of supporting code, depending on how much we wish to support. This
commit implements the common, basic uses:
- Choosing layouts, variants and options
- Switching groups
- Switching shift-levels
- Setting modifiers
Though some stuff is missing. Further information in the comments.
test_input.c is updated to use the new input event interface. You can
change the layouts in input.c:init_input() and see what works and what
doesn't.

vte: This adds a dummy VTE subsystem. It will be used to emulate a vt100
terminal based on our console subsystem.
terminal: This ties together several subsystems including the output-, the
console- and the vte-subsystem.
The test_terminal test application can be used to test the terminal. It is
supposed to provide a full vt100 implementation which is displayed on all
available screens.
Most of the functionality here is not implemented yet and only a dummy function.
These will be added in later commits.

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

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 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.
