Added normal mode command `chainloader' as module chain.mod, which
	depends on normal.mod and _chain.mod.

	* conf/i386-pc.rmk (pkgdata_MODULES): Add `chain.mod'.
	(chain_mod_SOURCES, chain_mod_CFLAGS): Variables added.
	* include/grub/i386/pc/loader.h (grub_rescue_cmd_chainloader):
	Deleted prototype.
	* loader/i386/pc/chainloader.c (grub_rescue_cmd_chainloader): All
	but arguments parsing moved to ...
	(grub_chainloader_cmd): ... here.  New function.
	* include/grub/i386/pc/chainloader.h: New file.
	* loader/i386/pc/chainloader_normal.c: Likewise.
