into separate file grub/compiler.h and include it instead.

	zeroing of CRC field before computing CRC.

	* include/grub/types.h (UINT_TO_PTR): Removed. All users switched to
	grub_addr_t casts.
	(PTR_TO_UINT64): Likewise.
	(PTR_TO_UINT32): Likewise.

	Remove lib/crc.c - users updated to use gcrypt implementation.

	* grub-core/commands/crc.c: Removed.
	* grub-core/Makefile.core.def (crc): Module removed.
	* grub-core/commands/hashsum.c (aliases[]): Add crc alias.
	* grub-core/commands/hashsum.c (GRUB_MOD_INIT): Register crc command.
	* grub-core/commands/hashsum.c (GRUB_MOD_FINI): Unregister crc command.
