51a7fe8fbd Mark abs/labs/llabs as 19+ rather than 21+
The libc.map.txt file already defines these three functions as having
been introduced in API 19, but these header files had declared them as
21 and up.

See https://android-review.googlesource.com/c/platform/development/+/233407

imaxabs is already declared as 19 and up.

Test: build-ndk-prebuilts.sh && ./update_platform.py &&
  checkbuild.py && run_tests.py
Test: manually build app against 18 and 19

We can cut a lot of stuff out of the NDK's libandroid_support with this,
and reduce unnecessary relocations for all LP32 code. LP64 code should
be unaffected.

54f5d8331f libc fortify: make socket.h and stdlib.h use diagnose_if
Since realpath no longer needs to be overloaded, we can restore the
upstream source to purity. We'll be able to do this with most of the
other functions when we pull a newer clang in.

b97049c039 libc: Split FORTIFY into its own headers
This patch cleans up our standard headers by moving most of the FORTIFY
cruft out in to its own sandbox. In order to include the *_chk and
*_real declarations, you can either enable FORTIFY, or `#define
__BIONIC_DECLARE_FORTIFY_HELPERS`.

Both sys/select.h and strings.h are explicitly ignored by this patch.
Both of these files have very small __BIONIC_FORTIFY blocks, and don't
define any actual FORTIFY'ed functions (just macros, and 3 *_chk
functions).

This patch also makes the versioner ignore the FORTIFY implementation
headers, since we're guaranteed to pick the FORTIFY'ed headers up when
looking at the regular headers. (...Not to mention that making the
FORTIFY'ed headers freestanding would be annoying to do and maintain for
~no benefit).

We bake the knowledge of where FORTIFY headers live directly into the
versioner. We could go with a more general approach (e.g. adding an -X
IGNORED_FILE flag that tells the versioner to ignore
$HEADER_PATH/$IGNORED_FILE), but we'd then have to repeat that for every
test, every manual invocation of the versioner, etc. for no benefit
that's obvious to me.

Bug: 12231437
Test: m checkbuild on bullhead internal master + CtsBionicTestCases. no

7cc779f15c libc: add clang FORTIFY support
This patch adds clang-style FORTIFY to Bionic. For more information on
FORTIFY, please see https://goo.gl/8HS2dW . This implementation works
for versions of clang that don't support diagnose_if, so please see the
"without diagnose_if" sections. We plan to swap to a diagnose_if-based
FORTIFY later this year (since it doesn't really add any features; it
just simplifies the implementation a lot, and it gives us much prettier
diagnostics)

b8e1b705d1 Make the legacy inline headers compile standalone.
It's useful to have the legacy inlines compile by themselves, both to
make header unification easier, and to ensure that the inline versions
match the regular declarations. Notably, this wasn't true for
sigismember, which took a const sigset_t* in the regular header, and
sigset_t* in the inline version.
