Static inclusion of filesystem modules to the main libgnomevfs-2.
Used for fully static GNU/Linux distribution independent binaries.
It may be also useful for Gnome OS based embedded network devices.
Patch based on --with-included-modules of Pango and inspired by
--disable-modules/--with-included-loaders of GTK+.

Name of the included filesystem is assumed to be both its own 'module name'
and 'method name' to prevent the dependency on GnomeVFS configuration files
(prevented by Bug # 127114).
'module name'->'method name' assumption is not the case for the regular .so
modules.
