Update.
	* elf/dl-version.c (_dl_check_map_versions): New argument trace_mode.
	Before testing versions check that we actually loaded the object
	and whether we are in trace mode.  If not loaded during tracing don't
	test versions in this object.
	(_dl_check_all_versions): Take new parameter and pass to
	_dl_check_map_versions.
	* sysdeps/generic/ldsodefs.h: Update prototypes for
	_dl_check_all_versions and _dl_check_map_versions.
	* elf/rtld.c (struct version_check_args): Add dotrace.
	(version_check_doit): Pass args->dotrace to _dl_check_all_versions.
	(dl_main): Pass info about trace mode to version_check_doit.
	* elf/dl-open.c (dl_open_worker): Pass zero as new argument to
	_dl_check_all_versions.

	* manual/users.texi (XPG Functions): Document utmpxname, getutmp,
	and getutmpx.
	Patch by Bryan Henderson <bryanh@giraffe-data.com>.
