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.

Allow user code to be compiled with "-mhard-float" for armeabi-v7a
(which implies -mfloat-abi=hard), and either link with
1. Android native APIs which use softfp, or
2. A customized libm_hard.a which is compiled with -mhard-float. Need
-D_NDK_MATH_NO_SOFTFP=1
See tests/device/hard-float/jni/Android.mk for details and restriction
on Clang

1. Sync bionic's, remove mips-specific one
2. Fix statfs.c to transfer the new f_flags too
3. Revise comment about --wrap=symbol

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.
See http://b.android.com/55749

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.
BUG=57267
Change-Id: Ib334e8fe95a3f592d5d4bb157b0f123984133597
- Add pread64(), pwrite64(), ftruncate64() for API level 11
- Cleanup declaration of lseek64() to use off64_t instead of loff_t
- Cleanup declaration of prctl() to use variable number of arguments
The cleanups are performed to better match upstream.

This patch fixes some formatting issues in <sys/cdefs.h>:
- change '#if __STDC_VERSION__ > xxx' into '#if defined(__STDC_VERSION__) && __STDC_VERSION > xxx'
- add __LIBC_HIDDEN__ definition (not technically required, but makes comparing the headers with upstream easier)

The atomic operations exported by the platform's C library do not
provide full memory barriers. This can result in incorrect results
when NDK machine code linked against them runs on multi-core devices.
While the bug has been fixed in the platform, this NDK header change
ensures that any source code that includes <sys/atomics.h> will end
up using a correct implementation of these functions, based on the
corresponding GCC builtins.
These builtins always provide a full barrier and have reasonable
performance. Application developers who depend on <sys/atomics.h>
should recompile their unmodified sources against this version
of the NDK as soon as possible.

This change removes the declaration of functions that are not
implemented by our various versions of our C library.
The corresponding declarations are moved inside #if 0 .. #endif
blocks (so it becomes easy to remember that they are missing)
Also refresh the headers a little (i.e. adding a few missing decl
and macros, remove C++ comments, etc)
See http://code.google.com/p/android/issues/detail?id=7807
Change-Id: I4ae1b1f3a181419eee2004c41b54768cc15e896f
NOTE: The missing decl are still there but encased in #if 0 .. #endif
blocks (to make it easier to implement them later). There are
a few exceptions in order to build STLport and libstdc++-v3
properly.
This commit removes duplication of system headers per platform, i.e. remove
copies of common headers like <stdlib.h> from arch-arm/usr/include and arch-x86/usr/include
and move them to a common include directory. More specifically:
- common headers: android-N/arch-A/usr/include --> android-N/include
- arch-specific headers: android-N/arch-A/usr-include --> android-N/arch-A/include
- arch-specific libs: android-N/arch-A/usr/lib --> android-N/arch-A/lib
Change-Id: Ifdba5038d108901931f3e3a7c14ebe6270d2d276
NOTE: This also contains careful separation of API-level-specific headers.
For example, platforms/android-5/include/pthread.h contains new function
declarations that are not available when using platforms/android-3/include/pthread.h
NOTE: The NDK's build-platforms.sh script has been updated to understand the new
layout. This change in develeopment/ndk does not change the layout of
platform files under $NDK/platforms after build-platforms.sh is called.
