Subject: 	* fhandler.cc (check_posix_perm): Moved here from syscalls.cc.
 	(fhandler_base::fpathconf): New method implementing (f)pathconf. 
 * fhandler.h (class fhandler_base): Declare fpathconf method. 	* path.cc
 (path_conv::check): Replace MAX_LINK_DEPTH with SYMLOOP_MAX. 	* path.h
 (MAX_LINK_DEPTH): Delete. 	* syscalls.cc (check_posix_perm): Move to
 fhandler.cc. 	(fpathconf): Call fhandler's fpathconf method. 	(pathconf):
 Build fhandler and call fhandler's fpathconf method. 	* sysconf.cc
 (sysconf): Reorder switch according to order of flags 	in sys/unistd.h.  Add
 handling for some missing flags. 	* include/limits.h: Reorder according
 to SUSv3 description.  Add some 	missing definitions.  Add comments. 
 * include/sys/syslimits.h: New file overriding newlib's syslimits.h 	file.
