9d93986481 Add functions in sysinfo.h.
Bug: 17703902

60d84af172 sysconf(3) returns long.
On LP32, this makes no difference. Not an ABI change.

On LP64, results are going to be in %rax or x0 whether they're 32- or 64-bit,
and the only difference is going to be whether the top bits are clobbered.

168667c972 Add non-macro stdin/stdout/stderr too.
Various C and C++ standards explicitly say that stdin/stdout/stderr
should be macros, but glibc makes them global variables too. This
means it's possible to write code that uses those names as locals,
but that code (toybox being an example) won't build on bionic.

If we'd done this earlier, we could have hidden __sF for LP64, but
it's too late now.

95f197f998 Allow stdatomic.h to be included from mingw prebuilt.
Define __GNUC_PREREQ if it isn't already defined.
This is a bit ugly, but it seems to be easiest to make this header as
context-independent as possible.  Together with the addition of a symbolic
link to this file from the mingw prebuilt, this appears to unblock
commit e9fa6be333e35d9e7ae435aeb32532875b95fe22.

0ac0df84c7 Fix struct stat to match POSIX 2008.
Our representation of sub-second times matched the Linux kernel, and we
provided macros for glibc source compatibility. This change switches us
over to match POSIX 2008, adds the macros they insist on (for compatibility
with earlier versions of POSIX), and also adds macros for compatibility
with any code that expects the kernel or old bionic names.

Unfortunately this breaks strace which defines its own structures using
the kernel names, and thus implicitly assumes that there are no macros with
those names, but this does allow the rest of the tree to build.

b20c24456e Implement all the POSIX _l functions.
Strictly speaking, this only implements the _l variants of the functions
we actually have. We're still missing nl_langinfo_l, for example, but we
don't have nl_langinfo either.

Dan Albert
658727e111 Inline helpers need to be exported unmangled.
__open_2() is used by the fortify implementation of open(2) in
fcntl.h, and as such needs an unmangled C name. For some reason
(inlining?), this doesn't cause problems at the default optimization
level, but does for -O0.

The rest of these didn't cause build failures, but they look suspect
and probably will, we just haven't caught them yet.

1aaa17802c cdefs.h: add artificial attribute to FORTIFY_SOURCE functions
Otherwise the gcc compiler warning doesn't show up.

Add -Wno-error to fortify related tests. Fortify related tests
are expected to be examples of bad programs, and in many
cases shouldn't compile cleanly. Rewriting them to compile
cleanly isn't feasible nor desirable.
