major -- an unsigned integer for the required major version
minor -- an unsigned integer for the required minor version
micro -- an unsigned integer for the required micro version

Returns nil if the GLib C library against which the Lisp binding is running is compatible with the given version, or a string describing the version mismatch.

(glib:check-version 2 84 0) => NIL
(glib:check-version 2 99 0) => "GLib version too old (micro mismatch)"
