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

Test: Unit tests pass, debuggerd run on processes on target.

Change the dmabufinfo library to handle multiple references to the same
buffer across PIDs by doing these changes:
- Add function AppendDmaBufInfo: appends the information for a specific
PID to an existing DmaBuffer vector
- Change the way fd/map references to a buffer belonging to a PID are
stored in DmaBuffer from vector<pid_t> to unorderedmap<pid_t, int>
- When parsing proc/%pid/{maps|fds}, look up the buffer by inode and
update the data if found

We no longer use these methods since they require write access to the
userdata block device. This patch removes them to simplify FiemapWriter,
and avoid opening userdata with write permissions.

This command erroneously reports that no GSI is installed, because
/metadata is not mounted in recovery. To address this, temporarily mount
/metadata when the gsi command is invoked.

It looks like this code is dead currently. From history, this was
meant to be used as a way to check that the recovery image is what was
expected during runtime, but that effort never completed, and we have
full verification of the recovery image when booting into recovery
anyway.
The code is functionally dead as is too, since /recovery doesn't
actually exist in any fstab, since recovery is either mounted as a
ramdisk during recovery or not mounted during normal boot.

The PDK doesn't have frameworks/base, so having a dependency from adb to
a library in there breaks the build. #ifdef out fastdeploy until we
figure out what we're going to do here, to unbreak the PDK build.

Load resources from /product/etc/res/{values,images}/charger. If a

If the device has GSI flashed, resources may exist in both paths.
Resources in /product is used with a higher priority.

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.

* 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.
