[glib/ebassi/c99-int-types] Drop custom re-implementation of C99 integer types

[Emmanuele Bassi <ebassi src gnome org>]

commit b7f73d920f735e0c8bab7d83dedc3cda7682e142
Author: Emmanuele Bassi <ebassi gnome org>

    Drop custom re-implementation of C99 integer types
    
    We have required a strict equivalence between our integer types and
    their C99 counterparts for two years and four cycles, and nobody
    complained about it.
    
    It is time to drop one of the few remaining vestiges of C89
    compatibility.
