Fix syslog fputs_unlocked namespace (bug 18530).
syslog (XSI POSIX) brings in references to fputs_unlocked (not POSIX). This patch fixes this by making fputs_unlocked into a weak alias for __fputs_unlocked and using __fputs_unlocked as needed. (No linknamespace test XFAILs are removed because there are other failures from syslog as well.) Tested for x86_64 and x86 (testsuite, and comparison of disassembly of installed stripped shared libraries). Disassembly of installed stripped shared libraries is unchanged on x86_64; on x86, I see some small changes to instruction ordering and register choice, with no apparent reason for such changes to be related to this patch, but they also seem completely harmless with no change to code size. [BZ #18530] * libio/iofputs.c [!_IO_MTSAFE_IO] (__fputs_unlocked): Define as strong alias of _IO_fputs. Use libc_hidden_def. * libio/iofputs_u.c (fputs_unlocked): Rename to __fputs_unlocked and define as weak alias of __fputs_unlocked. Use libc_hidden_weak. * include/stdio.h (__fputs_unlocked): Declare. Use libc_hidden_proto. * misc/syslog.c (__vsyslog_chk): Call __fputs_unlocked instead of fputs_unlocked.
