Putting libmemunreachable in the global C++ namespace was an oversight,
move it into namespace android.

Vendor blobs on ryu mprotect heap pages, causing a single chunk mapping
to appear as multiple mappings. The heap iterator has to expand the
requested range to cover the beginning of the chunk to find the chunk
metadata, which will lead to duplicate identical allocations being
reported from iterating over each of the split mappings. Silently
ignore identical allocations, and only warn on non-identical allocations
that overlap.

Vendor blobs on ryu mprotect heap pages, causing segfaults when dumping
unreachable memory. Handle segfaults within HeapWalker by mapping a
zero page over any unreadable pages. HeapWalker runs in the forked
process, so the mapping will not affect the original process.
