checkpatch: warn about using glib typedefs like gchar or gint

We should not use glib typedefs for basic C types char, short, int,
long, float or double. We commonly do not use them, so enforce
consistency.

That is not true for typedefs like guint, which we commonly use
because it's shorter typing than "unsigned int" (or "int unsigned"
or "unsigned"). Whether or not to use guint is left undecided at this
point.
