Yaakov Selkowitz 576093d46b ssp: add Object Size Checking for stdio.h, part 1
The implementation is mostly from NetBSD, except for switching fgets to
pure inline, and the addition of fgets_unlocked, fread, and fread_unlocked
for parity with glibc.  The following functions are also guarded in glibc:
asprintf, dprintf, fprintf, printf, vasprintf, vdprintf, vfprintf, vprintf.

Corinna Vinschen e18b7ffa48 stdio.h: Don't define unlocked macros using static inline on C++
In C++, the usage of static inline functions for getchar_unlocked and
putchar_unlocked may result in error messages like

  error: ‘_putchar_unlocked’ was not declared in this scope

Fix this by not using the _getchar_unlocked and _putchar_unlocked
macros in C++.

Sebastian Huber b0f271d1db Proper locking for getchar() and putchar()
Add internal inline functions _getchar_unlocked() and
_putchar_unlocked() if __CUSTOM_FILE_IO__ is not defined.  These
functions get _REENT only once.  Use them for getchar_unlocked() and
putchar_unlocked().  Define getchar() and putchar() to these unlocked
internal functions if __SINGLE_THREAD__ is defined, otherwise use the
external functions to use proper locking of the FILE object.

Assumes that __SINGLE_THREAD__ is not defined if __CYGWIN__ is defined.

Yaakov Selkowitz c347bb6469 stdio.h: guard function macros with !__cplusplus
While POSIX allows these functions to also be defined as macros in C, in
C++ this is not allowed, and prevents these names (particularly feof) from
being used in a custom namespace.

Yaakov Selkowitz 95644157c1 Feature test macros: ctermid, cuserid
The proper location for these functions has always been <stdio.h>, however
XPG4 and SUSv2 did mandate a duplicate declaration in <unistd.h>.  cuserid
was dropped in SUSv3 (it was marked legacy since XPG4) and the ctermid
declaration in <unistd.h> was made optional and obsolete in SUSv4.

_LARGEFILE_SOURCE, which controls only these two functions, is implicitly

Yaakov Selkowitz feec81e571 Feature test macros overhaul: stdio.h
Throughout, remove references to __STRICT_ANSI__ and use the proper
internal macros and versions for C99, POSIX, ATFILE for the various *at
functions, or LARGEFILE for fseeko and ftello.

[v]asprintf are GNU extensions, but the *iprintf, *iscanf, and
*asnprintf functions are unique to newlib.

getw and putw were removed from POSIX.1-2001. funopen is BSD, and
fopencookie is GNU.

Corinna Vinschen 6b97fabf1b Use __sputc_r inline code when building with gcc
Per the preceeding comment this inline code is disabled since 1993(!)
because of a bug in GCC at the time.  This is long gone and the equivalent
inline code is used in the BSDs for quite some time.  Enable this code for
newlib as well.

Jon Turney c5fee55606 stdio.h: Use __POSIX_VISIBLE etc. guards for POSIX 1003.1:2001 functions
Current mesa expects stdio.h to prototype fileno() when compiling with gcc
-std=c99 -D_XOPEN_SOURCE

Fix the 'POSIX 1003.1:2001' block in stdio.h to prototype functions if not
__STRICT_ANSI__, or _BSD_SOURCE, _POSIX_C_SOURCE or _XOPEN_SOURCE are defined
appropriately

As far as I can tell, despite being in this block, setbuffer() and setlinebuf()
are BSDisms which aren't in POSIX 1003.1:2001
