Extending linknamespace tests to cover libcrypt showed that crypt
brings in references to snprintf, but is in XPG3 and XPG4 which don't
have snprintf. This patch fixes it to use __snprintf instead,
exporting __snprintf from libc.so at version GLIBC_PRIVATE and adding
libc_hidden_proto / libc_hidden_def accordingly.
Tested for x86_64 and x86, in conjunction with the testsuite changes
to enable linknamespace testing for libdl and libcrypt. Also tested
(compilation only) for powerpc to make sure there were no problem
interactions with the optional-long-double handling for snprintf.
[BZ #20829]
* stdio-common/Versions (__snprintf): Add to version
GLIBC_PRIVATE.
* include/stdio.h (__snprintf): Use libc_hidden_proto.
* stdio-common/snprintf.c (__snprintf): Use libc_hidden_def.

This patch added a new fmemopen version, for glibc 2.22, that aims to be
POSIX complaint. It fixes some long-stading glibc fmemopen issues, such
as:
* it changes the way fseek with SEEK_END works on fmemopen to seek
relative to buffer size instead of first '\0'. This is default mode and
'b' opening mode does not change internal behavior (bz#6544).
* fix apending opening mode to use as start position either first null
byte of len specified in function call (bz#13152 and #13151).
* remove binary option 'b' and internal different handling (bz#12836)
* fix seek/SEE_END with negative values (bz#14292).
A compatibility symbol is provided to with old behavior for older symbols
version (2.2.5).
* include/stdio.h (fmemopen): Remove hidden prototype.
(__fmemopen): Add new hidden prototype.
* libio/Makefile: Add oldfmemopen object.

The getpass function (XPG3 / XPG4 / UNIX98) calls fflush_unlocked (not
in any of those standards). This patch fixes this by making
fflush_unlocked into a weak alias for __fflush_unlocked and calling
__fflush_unlocked from getpass.
Tested for x86_64 and x86 (testsuite, and that disassembly of
installed stripped shared libraries is unchanged by the patch).
[BZ #18540]
* libio/iofflush.c [!_IO_MTSAFE_IO] (__fflush_unlocked): Define as

syslog functions bring in references to dprintf, which wasn't added to
POSIX until the 2008 edition and so isn't in various standards
containing the syslog functions. This patch fixes this by making
dprintf into a weak alias of __dprintf and using __dprintf as
appropriate.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).
[BZ #18534]

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

libc_hidden_weak.

libc_hidden_proto.
* misc/syslog.c (__vsyslog_chk): Call __fputs_unlocked instead of
fputs_unlocked.
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.

While trying to get nptl/tst-initializers1.c to include the test skeleton, I
came across a couple of speed bumps. Firstly: after making the appropriate
changes to the test, running `make check' led to this error:
> In file included from ../malloc/malloc.h:24:0,
..
> from tst-initializers1.c:60:
> ../include/stdio.h:111:1: error: unknown type name `wint_t'
> extern wint_t __getwc_unlocked (FILE *__fp);
So, `wint_t' is used before being defined. Question: Why did test-skeleton.c
not cause this error in any of the other tests that include it?
Anyway, I noticed include/stdio.h includes stddef.h, which in turn defines
`wint_t', but only if `__need_wint_t' is defined. So I put in a
`#define __need_wint_t' before the include to get rid of the error. Is that
the correct fix?
A subsequent `make && make check' led to this second error:
> from tst-initializers1-c89.c:1:
> ../test-skeleton.c: In function `main':
> ../test-skeleton.c:356:11: error: `for' loop initial declarations are only
> allowed in C99 mode
> for (struct temp_name_list *n = temp_name_list;
Although there seem to be several other C89 no-noes in test-skeleton.c, I
needed only to fix this specific one for gcc-4.8.3 to stop complaining.
__get_nprocs is called from malloc code, but calls fgets_unlocked,
which is not an ISO C or POSIX function. This patch fixes it to call
a new __fgets_unlocked name instead.
Note: there are various other uses of fgets_unlocked in glibc's
libraries, and I haven't yet investigated which others might also be
problematic (called directly or indirectly from standard functions)
and so need to change to use __fgets_unlocked.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).
[BZ #17582]
* libio/iofgets.c [weak_alias && !_IO_MTSAFE_IO]
(__fgets_unlocked): Add alias of _IO_fgets. Use libc_hidden_def.

libc_hidden_weak.

tzfile.c is brought in by various ISO C functions, but calls fileno,
fread_unlocked and ftello, which are not ISO C functions. This patch
adds names __fileno, __fread_unlocked and __ftello for those
functions, making tzfile.c use those new names.
Note: there are various uses of fileno elsewhere in glibc that I
didn't change, although it may turn out that some of those also need
to use __fileno.
Tested for x86_64 with the glibc testsuite. Changed line numbers in
tzfile.c cause changes in assertions, and for some reason this ends up
with different instruction choice and register allocation, affecting
the size of __tzfile_read and so making comparison of disassembly for
libc.so problematic.
[BZ #17583]
