Summary:
While cross-compiling, a custom nm program may be required. This will also allow for the
use of llvm-nm if desired.

Summary: When using 32-bit python with 64-bit asan the pc array in sancov.py cannot fit in 64-bit pc's because the type-code 'L' for
arrays in python corresponds to the C type long which is only of 4 bytes. Because of this some of the coverage tool tests fail on
mips. To fix these test possible solutions are to use 64-bit python or use struct.unpack with the 'Q' type-code. We have used
struct.unpack with 'Q' type code since it is not appropriate to have a 64-bit python on all hosts.

Also, sized-delete with size_t == unsigned int.
These guys appear when building for Android with gnu-stl.
Fixes a number of ASan tests in that particular configuration.

Python may not be /usr/bin/python on some systems. For example, on
FreeBSD it will be /usr/local/bin/python.

They are not part of check-all :(
This change adds sized-delete operators to the version list, and disables the
hack that excluded versioned symbols from the dynamic list - this is not an
issue in this case.

This way does not require a __sanitizer_cov_dump() call. That's
important on Android, where apps can be killed at arbitrary time.
We write raw PCs to disk instead of module offsets; we also write
memory layout to a separate file. This increases dump size by the
factor of 2 on 64-bit systems.

Summary:
Sandboxed code may now pass additional arguments to
__sanitizer_sandbox_on_notify() to force all coverage data to be dumped to a
single file (the default is one file per module). The user may supply a file or
socket to write to. The latter option can be used to broker out the file writing
functionality. If -1 is passed, we pre-open a file.

- 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.
