	Move utility functions to common/.
	* cli/cli-utils.c (skip_spaces, skip_spaces_const, skip_to_space_const):
	Move defs to common/common-utils.c.
	* cli/cli-utils.h (skip_spaces, skip_spaces_const, skip_to_space)
	(skip_to_space_const): Move decls to common/common-utils.h.
	* common/common-defs.h: Move include of common-types.h before
	common-utils.h.
	* common/common-utils.c: Include host-defs.h and ctype.h.
	(HIGH_BYTE_POSN, is_digit_in_base, digit_to_int, strtoulst): Move
	from utils.c.
	(skip_spaces, skip_spaces_const, skip_to_space_const): Move from
	cli/cli-utils.c.
	* common/common-utils.h (strtoulst): Move decl from utils.h.
	(skip_spaces, skip_spaces_const, skip_to_space, skip_to_space_const):
	Move from cli/cli-utils.h.
	* common/host-defs.h: Include limits.h.
	(TARGET_CHAR_BIT, HOST_CHAR_BIT): Moved from defs.h.
	(skip_spaces, skip_spaces_const): Move decls from cli/cli-utils.h.
	* defs.h (TARGET_CHAR_BIT, HOST_CHAR_BIT): Move to
	common/common-utils.h.
	* utils.c (HIGH_BYTE_POSN, is_digit_in_base, digit_to_int)
	(strtoulst): Move to common/common-utils.c.
	* utils.h (strtoulst): Moved decl to common/common-utils.h.
