Modified files:
	bfd            : ChangeLog cache.c config.in configure 
	                 configure.in sysdep.h 

Log message:
	bfd: Make bfd_cache_max_open depend on actual open file limit.
	
	The current hard coded limit of open files in bfd/cache.c is 10. This
	is pretty low these days. Binaries are often linked against much more
	than 10 files (and sometimes against more than 100 shared libraries).
	When debugging with GDB some files are opened and closed multiple
	times because of this low limit. If possible make the BFD cache file
	limit depend on the actual open file limit of the process so more BFD
	files can be open at the same time.
	
	* cache.c (BFD_CACHE_MAX_OPEN): Remove define.
	(max_open_files): New static int initialized to zero.
	(bfd_cache_max_open): New static function to set and return
	max_open_files.
	(bfd_cache_init): Use bfd_cache_max_open.
	(bfd_open_file): Likewise.
	* configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
	(AC_CHECK_FUNCS): Add getrlimit.
	* configure: Regenerated.
	* config.in: Likewise.
	* sysdep.h: Check and include sys/resource.h for getrlimit.
