Include a stripped-down version of fribidi to avoid the extra dependency.

	* configure.in pango/pango-utils.[ch] pango/Makefile.am
	pango/mini-fribidi/*: Include a stripped-down version of fribidi
	to avoid the extra dependency. No fribidi symbols are
	exported so conflicts with the real fribidi should not
	happen. Library can optionally be compiled with the
	real libfribidi.

	* pango/pango-utils.[ch]: Wrappers for
	fribidi_ functions when compiling with fribiid.

	* modules/basic/basic-ft2.c modules/basic/basic-win32.c
	modules/basic/basic.c modules/thai/thai.c pango/Makefile.am
	pango/itemize.c pango/pango-context.c pango/pangoft2.c
	pango/pangowin32.c pango/pangox.c: Use pango_ versions of fribidi
	functions.
