build: remove glib dependency
We no longer require glib, yeah! Drop the mandatory glib dependency from
all build-files. Notice that there is not a single dependency, anymore,
except for libc.
We still have a not-mentioned pango dependency but this can be replaced
with freetype or a static font renderer so we currently do not care.

unicode: implement ucs4 to utf8 encoding
This is the last glib dependency so add a short conversion helper and we

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.
