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.

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

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)

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.
