Vladimir 'phcoder' Serbinenko 99ce1597a4 Add LZSS Mach-O support (needed for new xnu kernelcache).
* grub-core/Makefile.core.def (xnu): Add file lzss.c
	* grub-core/loader/lzss.c: New file.
	* grub-core/loader/xnu.c (grub_xnu_load_driver): Close binaryfile
	on Mach-O open failure.
	* grub-core/loader/macho.c (grub_macho_close): Free uncompressedXX.
	Don't free cmdsXX in uncompressedXX is set.
	(grub_macho_file): Init new fields.
	New argument is_64bit. All users updated.
	Handle compressed. Error out if no suitable architecture is found.
	Don't close file.
	(grub_macho_open): New argument is_64bit. All users updated.
	* grub-core/loader/macho32.c: Add defines for new fields.
	* grub-core/loader/macho64.c: Likewise.
	* grub-core/loader/machoXX.c (grub_macho_contains_macho): Make static.
	(grub_macho_parse): Handle compressed.
	Defer actual processing if compressed.
	(grub_macho_cmds_iterate): Decompress if compressed. New argument
	"filename". All users updated.
	(grub_macho_size): New argument "filename". All users updated.
	(grub_macho_get_entry_point): Likewise.
	(grub_macho_load): Handle compressed.
	* include/grub/macho.h (grub_macho_lzss_header): New struct.
	(GRUB_MACHO_LZSS_OFFSET): New define.
	(grub_decompress_lzss): New proto.
	* include/grub/machoload.h (grub_macho_file): New fields to handle
	compressed.
	(grub_macho_contains_macho64): Remove proto.
	(grub_macho_contains_macho32): Likewise.
	* util/grub.d/30_os-prober.in: Use kernel cache if available.
