Small modifications to the dump_stack method and added unit tests to
verify the output.

This is the userspace component for the improved shared memory buffer
tracking.
A new static library called libdmabufinfo will provide APIs to parse dmabuf
debugfs entries. The library can also map and read the file descriptors
per process to cross-reference the global data per process.
This change only adds a global API to read dmabuf stats from debugfs.

Previously information from the fstab was needed for this test, but
that's not longer the case, so skip reading the fstab altogether.

* changes:
fs_mgr: test parsing all mount and fs mgr options
fs_mgr: convert parse_flags over to C++
fs_mgr: store file_contents_mode and file_names_mode directly
We were logging "fd.get()" after we had already done a
"std::move(fd)". That won't log the value we were hoping for.
We instead cache the file descriptor value in a local int prior
to the move(), and log that.

vsock is a socket address family for communicating into and out of
virtual machines. Addresses have a port and CID. The CID is unique to
each virtual machine on the computer. The VM host always has CID 2.
http://man7.org/linux/man-pages/man7/vsock.7.html
Inside the android guest, the adb daemon hosts a vsock server with
VMADDR_CID_ANY, automatically using the guest CID. The adb server
can now connect to addresses of the form vsock:cid:port, where the CID
must be specified and the port defaults to 5555.
This is a significant speed improvement for ADB connections in
Cuttlefish, with 150-200 MB/s for `adb push` and 100-150 MB/s for
`adb pull`. It also allows removing some proxying steps from Cuttlefish,
simplifying the full connection path, and removes a dependency on the
unstable ivshmem protocol.
Commands tested against a Cuttlefish VM with CID 3:
adb connect vsock:3:5555
adb -s vsock:3:5555 shell
adb disconnect vsock:3:5555
Supporting "adb disconnect" and "adb -s" required modifying some of the
parts that parse addresses / serials.

It doesn't really make sense to have extra logic to convert these
strings to enums then back again to strings for usage, especially
since with the C++ fstab, these strings are small enough to fall into
the small string optimization of std::string.
This will help make future changes cleaner as well.

Since we are moving the fstab from DT into the ramdisk fstab, the
logging from ReadFstabFromDt when reading the default fstab is
turning into logging noise.
