This is the last glib dependency so add a short conversion helper and we
can finally drop glib. Anyway, the pango libs still depend on glib so
there is currently still a glib dependency, but it is no longer direct and
we can always choose the freetype font renderer to drop it.

Replace the glib dependency with the new in-house dynamic-array
implementation. Now there is only one utf8 glib dependency left that we
need to convert so we can drop glib-dependency.

There is really no need to use these glib types here. They are relicts
from the time when we used the glib hashtable so we can safely replace
them now.

It really doesn't make sense to expect an integer here as memcmp() and
friends use an integer, too, but in reversed logic. So use bool to avoid
confusion.

Small stuff that is not worth putting into a separate library is no moved
into the "static" library which is statically linked into all our
subsystems.

Sometimes we need to reset the UTF8 state-machine, for instance when
resetting the VTE. This function simply resets the internal state to
KMSCON_UTF8_START so we start all over on the next input character.

A symbol table should never be created twice therefore we can make it
static and global. We add locks so it is totally thread-safe, too.

The state machine is used to convert a stream of UTF8 data into UCS4
characters. It is slightly based on the machine found in the
wayland-compositor demos.

log_warn is much shorter and we already use log_err instead of log_error
so this is more consistent now.

Allow converting a ucs4 string into a utf8 string. Also export the default
symbol so other subsystems may use it.

Instead of allocating big buffers with kmscon_char's for every character we now
reduce a single character to an integer. This integer is either the Unicode
codepoint or an ID to an internally allocated string.
The so called kmscon_symbol_t integer can now be used as if it were a classic
"char" value without bothering with combining marks etc.
