Some linux headers are broken on older kernels.
Instead of depending on the constants and types from such headers directly,
we provide our own definitions and then verify them with compile-time
assertions. This makes the dependency on the headers test-only and would allow
switching to some other way of testing on older kernels, or even disable the
tests as the last resort (after all, kernel interfaces are supposed to be
stable).

- Introduce several new custom glibc wrappers
- Implement some of the not yet implemented wrappers
- Refactor and extend the tests
- Add script to make sure all declare custom glibc wrappers are implemented & tested.

the tests produce episodic flakes
the hypothesis is that it's due to our "racy" race detection algorithm
sleeps should remove the flakes

(-Wl,-syslibroot was accidentally overridden by -isysroot from Clang on OSX 10.9)
-isysroot is a Clang/LLVM-GCC-specific option, but hosting libsanitizer for LLVM
with GCC on Darwin shouldn't work anyway, because of the missing blocks support.

- Add a bunch of glibc functions to the ABI list
- Group similar functions in the ABI

Summary:
Definitions we use in public sanitizer headers may
slightly conflict with the ones we use in private sanitizer runtimes.
Moreover, we generally forbid to include any system headers (like <stdint.h>)
in sanitizer runtime headers. This leads to inevitable duplication of selected
interface function declarations, but we decided to live with it.

This should build a separate set of embedded runtime libraries, supporting the
option product:
{PIC, static} x { Hard-float, soft-float }
The emphasis is on ARM platforms (Cortex-M4F, Cortex-M3, Cortex-M0) but X86
variants are also built where possible.

This header has not been supported at all for the last 2 major OS X releases.
Removed its include and the capture of related symbols.

I still don't know what is causing our bootstrapped LTO buildbots to fail,
but llvm r194701 seems to be OK and I can't imagine that these changes could
cause the problem.

Apple's bootstrapped LTO builds have been failing, and these changes (along
with llvm 194701) are the only things on the blamelist. I will either reapply
these changes or help debug the problem, depending on whether this fixes the
buildbots.
