Fix resolver if_* namespace (bug 17717).
Resolver code, brought in by pthreads (at least), uses if_* interfaces
that weren't in POSIX before 2001, resulting in linknamespace
failures. This patch changes those interfaces to be weak aliases of
__if_* and makes the resolver use __if_* directly.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by this patch).
[BZ #17717]
* inet/if_index.c (if_nametoindex): Rename to __if_nametoindex and
define as weak alias of __if_nametoindex. Use libc_hidden_weak.
(if_indextoname): Rename to __if_indextoname and define as weak
alias of __if_indextoname. Use libc_hidden_weak.
(if_freenameindex): Rename to __if_freenameindex and define as
weak alias of __if_freenameindex.
(if_nameindex): Rename to __if_nameindex and define as weak alias
of __if_nameindex.
* sysdeps/mach/hurd/if_index.c (if_nametoindex): Rename to
__if_nametoindex and define as weak alias of __if_nametoindex.
Use libc_hidden_weak.
(if_freenameindex): Rename to __if_freenameindex and define as
weak alias of __if_freenameindex.
(if_nameindex): Rename to __if_nameindex and define as weak alias
of __if_nameindex.
(if_indextoname): Rename to __if_indextoname and define as weak
alias of __if_indextoname. Use libc_hidden_weak.
* sysdeps/unix/sysv/linux/if_index.c (if_nametoindex): Rename to
__if_nametoindex and define as weak alias of __if_nametoindex.
Use libc_hidden_weak.
(if_freenameindex): Rename to __if_freenameindex and define as
weak alias of __if_freenameindex. Use libc_hidden_weak.
(if_nameindex_netlink): Use __if_freenameindex instead of
if_freenameindex.
(if_nameindex): Rename to __if_nameindex and define as weak alias
of __if_nameindex. Use libc_hidden_weak.
(if_indextoname): Rename to __if_indextoname and define as weak
alias of __if_indextoname. Use libc_hidden_weak.
* include/net/if.h [!_ISOMAC] (__if_nametoindex): Declare and use
libc_hidden_proto.
[!_ISOMAC] (__if_freenameindex): Likewise.
* resolv/res_init.c (__res_vinit): Use __if_nametoindex instead of
if_nametoindex.
* conform/Makefile (test-xfail-XPG4/grp.h/linknamespace): Remove
variable.
(test-xfail-XPG4/pwd.h/linknamespace): Likewise.
(test-xfail-UNIX98/aio.h/linknamespace): Likewise.
