Don't use INTDEF/INTUSE with _dl_argv (bug 14132).

Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this
patch replaces its use for _dl_argv with rtld_hidden_data_def and
rtld_hidden_proto.  Some places in .S files that previously used
_dl_argv_internal or INTUSE(_dl_argv) now use __GI__dl_argv directly
(there are plenty of existing examples of such direct use of __GI_*).

A single place in rtld.c previously used _dl_argv without INTUSE,
apparently accidentally, while the rtld_hidden_proto mechanism avoids
such accidential omissions.  As a consequence, this patch *does*
change the contents of stripped ld.so.  However, the installed
stripped shared libraries are identical to those you get if instead of
this patch you change that single _dl_argv use to use INTUSE, without
any other changes.

Tested for x86_64 (testsuite as well as comparison of installed
stripped shared libraries as described above).

	[BZ #14132]
	* sysdeps/generic/ldsodefs.h (_dl_argv): Use rtld_hidden_proto.
	[IS_IN_rtld] (_dl_argv_internal): Do not declare.
	(rtld_progname): Make macro definition unconditional.
	* elf/rtld.c (_dl_argv): Use rtld_hidden_data_def instead of
	INTDEF.
	(dlmopen_doit): Do not use INTUSE with _dl_argv.
	(dl_main): Likewise.
	* elf/dl-sysdep.c (_dl_sysdep_start): Likewise.
	* sysdeps/alpha/dl-machine.h (RTLD_START): Use __GI__dl_argv
	instead of _dl_argv_internal.
	* sysdeps/powerpc/powerpc32/dl-start.S (_dl_start_user): Use
	__GI__dl_argv instead of INTUSE(_dl_argv).
	* sysdeps/powerpc/powerpc64/dl-machine.h (RTLD_START): Use
	__GI__dl_argv instead of _dl_argv_internal.
