This fixes some issues with using boost's asio (which wrongly assumes
_BSD_SOURCE implies that these things are available) following our
change from -isystem to --sysroot.

These aren't part of the current UAPI headers. They're already gone
from the unified headers, but it would be good to remove them from
the legacy headers as well since it will help find the people that
are still using them (if any).

I'd actually fixed sys/cdefs.h quite some time ago, but that
definition of __pure2 was being clobbered by the bogus one in math.h.

This is all macros, so there's no reason to have one per API level.
This is still quite a ways from matching what we have in bionic, but
that's a problem for another day.

This CL unconditionally removes the existance of __builtin_isinf and
__builtin_isnan from math.h for clang, because (unlike other math functions)
clang doesn't like those to be declared.
See LLVM bugzilla entry: http://llvm.org/bugs/show_bug.cgi?id=20958
The reason for decorating all math functions with __attribute__((pcs("aapcs")))
is to offer developers the ability to compile their code with hardfp and still
link Android's libm.so which follows softfp calling convention.
Before issue 20958 is fixed, those who want clang to compile their code with
hardfp in NDK has to go all the way hard, ie.
1) LOCAL_CFLAGS += -mhard-float -D_NDK_MATH_NO_SOFTFP=1
Note that _NDK_MATH_NO_SOFTFP=1 remove __attribute__((pcs("aapcs"))) for all math functions
2) LOCAL_LDLIBS += -lm_hard # link libm_hard.a recompiled with -mhard-float instead of bionic libm.so

Upstream clang3.6 still doesn't allow change of calling convension of
__builtin_isnan from the default to "softfp" (via __attribute__((pcs("aapcs"))))
as required by bionic libm.so for 32-bit ARM. Let's hope clang3.7
fix that. See upstream bug http://llvm.org/bugs/show_bug.cgi?id=20958

It appears that upstream 3.5 still can't accept __builtin_isnan redeclared
with calling convention, eg.
cat > isnan.c <<EOF
int __builtin_isnan(double) __attribute__((pcs("aapcs")));
EOF
clang -target armv5te-none-linux-androideabi -c isnan.c
isnan.c:1:5: error: function declared 'aapcs' here was previously declared without calling convention
int __builtin_isnan(double) __attribute__((pcs("aapcs")));

Change-Id: Ibd2c3e168cfe7f6902fdc6eca2e2778d8ccf1fac
Similar to clang 3.3, it seems that clang 3.4 declares an incompatible
function prototypes for __builtin_isnan(). To workaround this issue,
we should not declare the function prototype for __builtin_isnan().
Note: Though it may be good to fix this in clang type checker, like
__builtin_nexttoward(), however it seems non-trivial since __builtin_isnsn()
might be overloaded. We can revert this after we have fixed the
clang builtin definition.

wait4() was incorrectly declared in <sys/wait.h>, but only added to the
C library in Android 4.3 (API level 18) [1]
This patch:
- Removes the wait4() declarations for any <sys/wait.h> header before
API level 19.
- Brings the API level 19 <sys/wait.h> which correctly declares wait4().
- Update the libc.so.functions.txt for API level 19 of all platforms
to include the exported symbol.
NOTE: This does not bring the static libc.a to API level 19, which means
it is stuck at API level 9 for ARM.
See [2] for the corresponding NDK tests.

Annotate __builtin math functions with __NDK_FPABI_MATH__ too.
1. __attribute__((pcs("aapcs"))) has no effect on codegen when __buitlin
function is emitted inlined.
2. When __builtin call into regular function in Android's libm, it has
proper attribute which observes soft float-abi

The mkdtemp() function has always been implemented in the C library
(see [1] for proof) but was missing a declaration in <stdlib.h>, until
Android 4.0.1 [2]
This patch simply adds the missing declaration to former <stdlib.h>
versions. This makes it easier to build certain open-source programs
for Android, because auto-tools probing typically looks at the symbols
in libc.so to define HAVE_MKDTEMP, then the source fails to compile
because of the lack of declaration.
Note that the mkdtemp is also already listed in
platforms/android-*/arch-*/symbols/libc.so.functions.txt, which were
generated by parsing actual system libraries, and thus don't need to
be updated here.

This fixes WCHAR_MIN / WCHAR_MAX to be signed / unsigned based on
the target ABI.
This only impacts ARM where wchar_t is really 'unsigned int'.
One can define _WCHAR_IS_ALWAYS_SIGNED to restore the old behaviour.
