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
new errors.

versioner: ignore non-header files.
Don't try to compile non-headers (vim swap files, etc.) that happen to
be in the header directory.
Bug: none
Test: manually created a file in libc/include

versioner: refactor to use CompilerInstance directly.
This will make it easier to switch over to a virtual filesystem,
which should drastically improve performance.
This also fixes an issue with warning/error reporting.

Minor copyright header unification.
Regenerating the NOTICE file the other day left me scratching my head at
various "how do they differ?" cases, resolved by this patch.
Test: N/A

versioner: replace availability attributes with annotate.
Major refactor to use __attribute__((annotate)) to be able to keep
track of the semantic differences between __INTRODUCED_IN(x) and
__INTRODUCED_IN_X86(x), for use in the upcoming preprocessor.

versioner: introduce.
Add a clang-based tool to inspect header availability attributes and
verify them against the NDK platform definitions.
