maint: address sc_bindtextdomain, sc_program_name and sc_prohibit_HAVE_MBRTOWC.

	* bootstrap.conf (gnulib_modules): Require progname.
	* src/complain.c, src/getargs.c, src/getargs.h, src/main.c: Use it.
	* cfg.mk (exclude): New.
	Use it.
	Skip lib/main.c for bindtextdomain and set_program_name.
(cherry picked from commit 4d699f44e65d29b4d49cf68d7a3b4bf856eb5d1b)

Conflicts:

	cfg.mk
