cpplib.h (struct cpp_buffer): Replace dir and dlen members with a struct file_name_list pointer.

	* cpplib.h (struct cpp_buffer): Replace dir and dlen members
	with a struct file_name_list pointer.
	(struct cpp_reader): Add pointer to chain of `actual
	directory' include searchpath entries.
	(struct file_name_list): Add *alloc pointer for the sake of
	the actual-directory chain.
	Move definition of HOST_WIDE_INT here.
	(cpp_parse_escape): Change prototype to match changes in
	cppexp.c.
	* cppfiles.c (actual_directory): New function.
	(finclude): Use it to initialize the buffer's actual_dir
	entry.
	(find_include_file): We don't need to fix up max_include_len
	here.
	* cpplib.c (do_include): Don't allocate a file_name_list on
	the fly for current directory "" includes, use the one that's
	been preallocated in pfile->buffer->actual_dir.  Hoist out
	duplicate code from the search_start selection logic.
	(cpp_reader_init): Initialize pfile->actual_dirs.
	Remove definition of HOST_WIDE_INT.  Change calls
	to cpp_parse_escape to match changes in cppexp.c (note
	hardcoded MASK, which is safe since this is the source
	character set).
	* cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
	to handle wide character constants in #if directives.  The
	function now returns a HOST_WIDE_INT, and takes a third
	argument which is a binary mask for all legal values (0x00ff
	for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.)  Define
	MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK.  Change callers of
	cpp_parse_escape to match.  [Fixes c-torture/execute/widechar-1.c]
