xfstests updates - rework build to be like other xfs packages, revive some old fs test tools and reenable xfs extensions, move ltp code into a separate subdir to help keeping in sync with real ltp project (hopefully)

+* NAME
+*       databingen - fill a buffer with a data pattern
+*
+* SYNOPSIS
+*       (void) databingen(mode, buffer, bsize, offset)
+*       int     mode;
+*       char    *buffer;
+*       int     bsize;
+*	int 	offset;
+*
+* DESCRIPTION
+*       datagen fills the buffer pointed to by 'buffer' with 'bsize' bytes
+*       of data of the form indicated by 'mode'.  
+*	All modes (expect r -random) are file offset based.
+*	This allows more than process to do writing to the file without
+*	corrupting it if the same modes were used.
+*	They data modes to choose from, these are:
+*
+*               'a' - writes an alternating bit pattern (i.e. 0x5555555...)
+*
+*               'c' - writes a checkerboard pattern (i.e. 0xff00ff00ff00...)
+*
+*		'C' - writes counting pattern (i.e. 0 - 07, 0 - 07, ...);
+*
+*		'o' - writes all bits set (i.e. 0xffffffffffffff...)
+*
+*		'z' - writes all bits cleared (i.e. 0x000000000...);
+*
+*               'r' - writes random integers
+*
+* RETURN VALUE
+*       None
