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

Switch x86 syscall stubs over to the ENTER/END style of the ARM stubs.
Also update the x86 asm.h to support this; we need it for libm assembler
anyway.
Also clean up the _FBSDID hack in <sys/cdefs.h>.

Upgrade libm.
This brings us up to date with FreeBSD HEAD, fixes various bugs, unifies
the set of functions we support on ARM, MIPS, and x86, fixes "long double",
adds ISO C99 support, and adds basic unit tests.
It turns out that our "long double" functions have always been broken
for non-normal numbers. This patch fixes that by not using the upstream
implementations and just forwarding to the regular "double" implementation
instead (since "long double" on Android is just "double" anyway, which is
what BSD doesn't support).
All the tests pass on ARM, MIPS, and x86, plus glibc on x86-64.

libc: Provide ucontext_t/mcontext_t/<sys/ucontext.h>
This patch updates the C library headers to provide ucontext_t
definitions for three architectures.
+ Fix <signal.h> to always define 'struct sigcontext'.
The new declarations are announced with new macros defined in
<sys/cdefs.h> in order to make it easier to adapt client code
that already defines its own, incompatible, versions of the
structures seen here.

disable _FORTIFY_SOURCE under clang
Clang and _FORTIFY_SOURCE are just plain incompatible with
each other. First of all, clang doesn't understand the
__attribute__((gnu_inline)) header. Second of all,
Clang doesn't have support for __builtin_va_arg_pack()
and __builtin_va_arg_pack_len() (see
http://clang.llvm.org/docs/UsersManual.html#c_unimpl_gcc)
Until we can resolve these issues, don't even try using
_FORTIFY_SOURCE under clang.

Fix the clang build: this compiler doesn't support the gnu_inline function attribute
Recent clang compiler doesn't have gnu_inline working. When frameworks/rs
is compiled with clang instead of gcc, it no longer works. Will be fixed
by this patch.

_FORTIFY_SOURCE: add memset / bzero support
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.

string.h: add __attribute__ ((pure)) to string functions
cdefs.h: Introduce the __purefunc attribute, which allows us to mark
certain functions as being "pure".
http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html
Many functions have no effects except the return value and their
return value depends only on the parameters and/or global variables.
Such a function can be subject to common subexpression elimination
and loop optimization just as an arithmetic operator would be.
string.h: Mark many commently used string functions as "pure", to
allow for additional compiler optimizations.
