Workaround issue where SYSTEM_UI_FLAG_IMMERSIVE_STICKY is invalidated
when a volume button is pressed (internal bug ref b/11986621)
Immersive mode still does not recover when the screen has been
rotated, due to onSystemUiVisibilityChange is not triggered
when screen is rotated (internal bug ref b/11990702)

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.

A math library compiled with -mhard-float. Build instructions:
1. cd to a recent Android source tree: bionic.git
fbefb252b09634114977dbd1b48dd42bb2629b83 (internal) in this case
2. Temporarily remove "-mfloat-abi=softfp" from build/core/combo/arch/arm/armv7*
and build/core/combo/TARGET_linux-arm.mk
3. Temporarily add "-mhard-float -mfloat-abi=hard" to LOCAL_CFLAGS
for libm.a in bionic/libm/Android.mk
4. make -B -j32 out/target/product/generic/obj/STATIC_LIBRARIES/libm_intermediates/libm.a
5. Rename it

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

1. Add sincos, sincosf, and sincosl to API >= 9 (for ARM only,
because X86 and MIPS have it already)
2. Add nan, nanf, nanl, and tgammaf to API >= 13 (11 actually,
but we don't want to add another API which is not released)
3. Add log2, log2f, log2l, logbl, nexttoward, and nexttowardl to
API >= 18

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.
