[glib] Replace all instances of ssize_t with gssize

[Philip Withnall <pwithnall src gnome org>]

commit 4a77eb16cecc7e3a076e046c6e890bee590a5c01

    Replace all instances of ssize_t with gssize
    
    ssize_t is supported widely, but not universally, so use gssize instead.
    Currently only one piece of code actually *needs* this change to be compilable
    with MSVC, the rest are mostly in *nix parts of the code, but these are changed
    too, for symmetry.
