edd6b437ae Filter functions based on files we scan. 
Currently we extract all functions from the compilation unit - it doesn't really make sense as it will try to process functions in included files too.
As we require sapi_in flag, we have information which files are of interest.

This change stores the top path in _TranslationUnit and uses it when looking for function definitions to filter only functions from the path we provided.

6332df5ef6 Fix or ignore type errors generated by the next release of pytype. 
The next release contains one major change: for function parameter annotations,
pytype will no longer treat (x: X = None) as equivalent to
(x: Optional[X] = None). This pytype behavior was based on an outdated version
of the type-checking spec. Annotations that were relying on the behavior now
need to explicitly declare themselves as Optional.

8a7d0d1cb3 Use a nested userns&mntns to pre-pivot_root 
This addresses a latency issue - chroot_fs_refs called inside pivot_root
in the kernel can take several milliseconds on machines with many threads
running.
This might not always reduce latency for custom forkservers, as additional
fork can be more costly than pivot_root.
