Remove use of GLIB_CHECK_VERSION()

GLib >= 2.34 is now required, so there is no need to check whether the
version is above 2.22.
Use GLIB_VERSION_MIN_REQUIRED, GLIB_VERSION_MAX_ALLOWED, etc

It will report warnings when the required version of GLib or GTK+ is not
correct.

For example if we use a new GTK+ function without bumping the dependency
version, a warning will be printed.

It assumes that GLIB_CHECK_VERSION() is not used, so the minimum
required version is the same as the maximum allowed one.
Adapt gtk_source_view_populate_popup()

The parameter of ::populate_popup() is now a GtkWidget instead of a
GtkMenu. See this commit:
