clang doesn't support attribute alloc_size, but GCC uses it to give
diagnostics where clang can't, and we had a test for one such case.

Various things:
* work around -Wnullability-completeness.
* use C++ casts in C++ and C casts in C.
* stop using attributes clang doesn't support (such as `warning`).
* remove duplicate definitions of XATTR_CREATE and XATTR_REPLACE.

These were removed from POSIX 2004. Hides the header declarations for all
targets, and hides the symbols for LP64.

malloc and family were not declared with __attribute__((alloc_size)).
This was (sometimes) preventing FORTIFY_SOURCE related functions
from knowing the size of the buffer it's dealing with, inhibiting
FORTIFY_SOURCE protections.
Add __attribute__((alloc_size))
Information about the alloc_size attribute can be found
at http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html

The function should take a 'const void*' parameter, instead of 'void*'.
Note that the implementation in upstream-dlmalloc/malloc.c already does
this.

Move dlmalloc code to upstream-dlmalloc to make pulling upstream changes
easier.
Declare pvalloc and malloc_usable_size routines present in malloc.h but with
missing implementations. Remove other functions from malloc.h that have
no implementation nor use in Android.

According to
http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html
realloc should NOT be marked with __attribute__((malloc)). Quoting:
realloc-like functions do not have this property as the memory
pointed to does not have undefined content.
For reference, __mallocfunc is defined in sys/cdefs.h as:
#define __mallocfunc __attribute__((malloc))
