Create font when resizing console
When resizing a kmscon_console object we automatically create a new font because
all cached objects get invalid now.

Add kmscon_font type
A kmscon_font object is used to store the current font information. It allows to
draw any kind of UTF-8 string to the screen. Internally, it uses kmscon_glyph to
store glyph information for every character that has been drawn so redrawing it
is much faster.
Currently, we only support GLYPH_LAYOUT as caching method which is quite slow.
However, it supports any kind of input and always works. Better and faster
caching algorithms like cairo_scaled_font_t will be added later.

Add pango dependency
We use pango to draw fonts. This requires glib and cairo support, too.

Add cells to console objects
A console has a fixed line and column count. Each entry is represented by a
kmscon_cell object. The console can be resized on the fly.

Add console test
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.

Add console drawing-logic
A console may be displayed on multiple outputs. We allow different screen
resolutions on these outputs so we need a way to map the console image onto
different outputs.
We simply render the console image into a cairo surface with a user-given
resolution. This should be set to the highest resultion of the used outputs. The
application can now map this image onto the different framebuffers. This will
scale the image if the target framebuffer is smaller than the cairo surface.
We also do not clear the framebuffer. This should be done by the user. This
allows us to draw with alpha values and blend the console on top of the current
framebuffer. We do not have to care for background images and the application
has full control of where the console is shown.

Add kmscon_char type
Every cell of the console contains one single printable character. We want to be
Unicode compatible so we must support combined characters. Hence, each cell
consists of a UTF-8 string that can be drawn by pango as a single glyph.

New kmscon project
The kmscon application is a terminal emulator which runs on a native linux DRI
device. It uses linux KMS and DRI to get a working OpenGL context without the
need of an X-Server, Wayland or similar.
It is an attempt to replace the in-kernel VT emulator with a full userspace
console.
