Adding gflags + some basic functionality to this binary. We should be
able to use this to write v2 or v3 cow, and then use inspect_cow to
inspect the contents
Test: write_cow

Gonna add to this binary options to write v2 + v3 cow, + some additional
configurations (for testing purposes). I think this binary can serve as
something to use in parallel with inspect_cow

Also, why are we accepting the completely made-up "RLIM_AS" but not the
real "RLIMIT_AS" in .rc files?

Rather than split this into two binaries as we did for libsnapshot, this
uses test parameterization. I went this route because even for async
builds, the sync path must always work as a fallback.

Merge thread will mark merge-completion after msync on header is
complete. This should be definitive enough to track the completion
status.

bionic hard codes the PAGE_SIZE macro as 4096. This is going away as
Android begins to support larger page sizes.
trusty uses PAGE_SIZE to round up the allocation size of the DMA
buffers and mmap sizes. This is not explicitly needed since the kernel
will always give you a page-aligned and page-sized multiple allocation
when allocating a dmabuf or mmap-ing.
Remove this PAGE_SIZE usage from TrustyApp, app_fuzzer, coverage,
line-coverage, modulewrapper.

bionic provides PAGE_SIZE macro which happens to also match the
4096 chunk size in the tips_test.
PAGE_SIZE is being removed as no other libc provides this and
Android is moving towards being page-size-agnostic.
Use 4096 chunk size for tipc-tests; fix incorrect size in
munmap cleanup; and add failure log for send-fd test.
Test: tipc-test -t "send-fd"

bionic provides PAGE_SIZE macro which happens to also match the
size keymaster send buffer (4096) and half the size of the recv
buffer.
PAGE_SIZE is being removed as no other libc provides this and
Android is moving towards being page-size-agnostic.
Use a 4096 constant instead.

tipc_fuzzer writes random data of length 'size' and then
attempts to read back data up to 'TIPC_MAX_MSG_SIZE' in length.
Since 'size' is unrestricted we can always write more than the
subsequent read; and in effect the fuzzer only checks that we
can read something.
Remove the read buffer's dependency on PAGE_SIZE.

Adding Version 3 of CowHeader. This will inherit from original
CowHeader and add a compression field. We are no longer supporting
different compressions per operation so having this one field is enough.
