This function has been removed from POSIX.
Unfortunately, we can't leave #define index(a, b) strchr((a), (b)) in its place
because defining a preprocessor macro for index() breaks a whole lot of code.

These symbols are still defined for LP32 for binary compatibility, but
the declarations have been replaced with the POSIX recommended #defines.

In 829c089f83, we disabled all
FORTIFY_SOURCE support when compiling under clang. At the time,
we didn't have proper test cases, and couldn't easily create targeted
clang tests.
This change re-enables FORTIFY_SOURCE support under clang for a
limited set of functions, where we have explicit unittests available.
The functions are:
* memcpy
* memmove
* strcpy
* strncpy
* strcat
* strncat
* memset
* strlen (with modifications)
* strchr (with modifications)
* strrchr (with modifications)
It may be possible, in the future, to enable other functions. However,
I need to write unittests first.
For strlen, strchr, and strrchr, clang unconditionally calls the
fortified version of the relevant function. If it doesn't know the
size of the buffer it's dealing with, it passes in ((size_t) -1),
which is the largest possible size_t.
I added two new clang specific unittest files, primarily copied
from fortify?_test.cpp.
I've also rebuild the entire system with these changes, and didn't
observe any obvious problems.

Also add a more intention-revealing guard so we don't have loads of
places checking whether our inlining macro is defined.

AFAIK, bionic only ever provided an implementation of bcmp
for x86, and even then, the code was never actually compiled.
Remove the prototype.
bcmp() has been obsoleted and replaced by memcmp()

Add _FORTIFY_SOURCE support for the following functions:
* memset
* bzero
Move the __BIONIC_FORTIFY_INLINE definition to cdefs.h so it
can be used from multiple header files.
