c1b44ecc53 Revert "libc: Provide ucontext_t/mcontext_t/<sys/ucontext.h>"
This creates build issues in the internal Android tree.
Will investigate later.

Original patch: https://android-review.googlesource.com/#/c/38875/

c124baaf29 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.

829c089f83 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.

4f1f149c37 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.

9b6cc223a3 FORTIFY_SOURCE: introduce __BIONIC_FORTIFY_UNKNOWN_SIZE macro

71a18dd435 _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.

a677907ee8 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.

23d24394e7 libc: Add <android/api-level.h>
Add a new header that defines __ANDROID_API__ as a constant integer
corresponding to the current native API level. This header is included
by <sys/cdefs.h>

Change-Id: Ib4774e247b395991266245815a24292afc919848
NOTE: This header is already provided by the NDK's platform headers.
      for levels 3 to 9.

50ace4fec5 Remove compiler warnings when building Bionic.
Also add missing declarations to misc. functions.
Fix clearerr() implementation (previous was broken).
Handle feature test macros like _POSIX_C_SOURCE properly.
