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.

In armeabi-v7a, VM still expects JNI functions to follow soft-abi.
Annotate it with __NDK_FPABI__ so compiler follows soft-abi in JNI
functions regardless the presence of -mhard-float in command-line.
It's up to developer to apply JNICALL consistently on JNI functions,
ie. those functions whose first arg has type "JNIEnv*" is likely to be

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.

Bionic does not have actual implementation of those functions.
Further implementations should be introduced in new
API-level in order to prevent break of compatibility.

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.

This patch ensures that wchar_t is a 32-bit number when targetting
API level < 9 (i.e. Froyo or older).
You can restore the previous (and broken) behaviour by defining
_WCHAR_IS_8BIT at compile time. See http://b.android.com/57267
for more context.

The new one also no longer undef offsetof and replaces it with
"((size_t) &((TYPE *)0)->MEMBER)" if __compiler_offsetof isn't
defined. The problem with the old behavior are that
1. __compiler_offsetof isn't defined in linux/compiler.h even though
all Android compilers support __builtin_offsetof
2. As as result, offsetof defined in stddef.h to use __builtin_offsetof
is undefined and replaced here. Problem is,
"((size_t) &((TYPE *)0)->MEMBER)" isn't considered a compile-time
constant, and fails some code expect offsetof to be.
