Fix open_memstream namespace (bug 18498).
open_memstream is new in the 2008 edition of POSIX. However, the older functions getopt, closelog and fmtmsg all bring in references to it. This patch fixes this in the usual way, making open_memstream into a weak alias of __open_memstream and calling __open_memstream from the relevant places. Tested for x86_64 and x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). 32-bit builds produce an XPASS for conform/POSIX/unistd.h/linknamespace after this patch (because the only cause of failure left there now is 64-bit specific); that will disappear once the 64-bit failure is resolved and the XFAIL removed at that time. [BZ #18498] * libio/memstream.c (open_memstream): Rename to __open_memstream and define as weak alias of __open_memstream. * include/stdio.h (__open_memstream): Declare. Use libc_hidden_proto. (open_memstream): Don't use libc_hidden_proto. * misc/syslog.c (__vsyslog_chk): Call __open_memstream instead of open_memstream. * posix/getopt.c (_getopt_internal_r): Likewise. * conform/Makefile (test-xfail-XPG3/stdio.h/linknamespace): Remove variable. (test-xfail-XPG4/stdio.h/linknamespace): Likewise. (test-xfail-UNIX98/stdio.h/linknamespace): Likewise. (test-xfail-XOPEN2K/unistd.h/linknamespace): Likewise.
