New patch below. Conditionals removed as suggested by cgf.

Define of _DIRENT_HAVE_D_TYPE still there - google code search finds 
several projects using this instead of a ./configure check.

	* dir.cc (readdir_worker): Initialize dirent.d_type and __d_unused1.
	* fhandler_disk_file.cc (fhandler_disk_file::readdir_helper):
	Set dirent.d_type based on FILE_ATTRIBUTE_*.
	* include/sys/dirent.h: Define _DIRENT_HAVE_D_TYPE.
	(struct dirent): Add d_type. Adjust __d_unused1 size to preserve layout.
	[_DIRENT_HAVE_D_TYPE]: Enable DT_* declarations.

PS: find is not as smart as expected: 'find /path -type d' calls lstat() 
for each entry, even if d_type != DT_UNKNOWN.
So 'find /path' is 2-3 times faster than 'find /path -type d'.
