[patch bfd]: Follow-up for dump of xdata SEH

Hello,

this patch replace the quadratic search of end address in xdata for a
given xdata-start address by a binary search. Additionally it changes
the misleading term "CFA" by "none".

2010-10-08  Kai Tietz

	* pei-x86_64.c (find_next_xdata_or_end): Removed.
	(pex64_dump_xdata): Remove arguments stop, onaline,
	and pdata. New argument endx.  Print term "none"
	instead of misleading "CFA".
	(sort_xdata_arr): New function.
	(pex64_bfd_print_pdata): Use binary search/sort for unwind-RVAs
	instead of searching quadratic.

Tested for x86_64-w64-mingw32. Ok for apply?

Regards,
Kai
