input: use libxkbcommon to convert input events
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

vt: fix race-condition in signal handling
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.

vt: add support for automatic VT switching
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.
