When Android userdata partition has been erased in fastbootd, call
oem specific API doOemSpecificErase() to wipe other userdata in
device.
If oem doesn't implement this specific API in fastboot_hal lib,
fastbootd will receive 'NOT_SUPPORTED' return status.

These logs are not generally useful and can be considered to be spam
by some. Drop them to VERBOSE so that we can be selectively enabled
when debugging logd.
Test: these logs do not appears by default.

Implement OpenSnapshotWriter for non-compressed Virtual A/B. This is
done by adding an OnlineKernelSnapshotWriter class, which forwards all
writes to a dm-snapshot block device.
This also introduces a new ISnapshotWriter class which extends
ICowWriter, and adds features specific to libsnapshot (versus ICowWriter
which is intended only for the new COW format). The OpenSnapshotReader
call has been moved here since the writer retains all the information
needed to create the reader.
To test the new call, vts_libsnapshot_test has been modified to use
OpenSnapshotWriter.
As part of this change, all consumers of libsnapshot must now link to
libsnapshot_cow.

Once COWs are allocated, their size is fixed, and we don't want to
write beyond the end. To make this validation less tedious, the virtual
methods of ICowWriter have been made internal. The user-facing API calls
do validation before calling the internal variants.

adb has been built without -Wnon-virtual-dtor because Soong doesn't turn
the flag for the host targets, and the flag can't coexist with
-Wexit-time-destructors.
However, the new host target linux_bionic_arm64 turns the flag on,
because it inherits most of the cflags from the device config.
That is forcing us to implement the virtual destructor, which isn't
possible due to -Wexit-time-destructors.
Solving the issue by explicitly turning -Wnon-virtual-dtor off so that
it is disabled also for the linux_bionic_arm64 target.

This simplifies some of the logic and removes the need to pass an
Arch value to functions that should already know about the arch
it is operating on.
Includes fixes for debuggerd/libbacktrace.
Added new unit tests to cover new cases.
Test: All unit tests pass.
Test: Faked unwinder failing to verify debuggerd error messages display
Test: properly in backtrace and tombstone.

Without enabling the encryption on this folder, we will not be able to
rename files from this folder to /data/app folder, since /data/app
folder is encrypted. Trying to rename files between unencrypted folder
to encrypted folder throws EXDEV error.
Turning on encryption for /data/app-staging has the following concerns:
1. Turning on the encryption will erase all of its content. But this is fine
since during OTA we fail all staged sessions anyway.
2. We need to create hardlinks from /data/app-staging to
/data/apex/active. This is also fine since we will be creating link from
encrypted folder (/data/app-staging) to non-encrypted folder and this
does not throw EXDEV error.

This patch changes the variable name `uid` to `userId` where it
denotes an Android user id. This makes it harder to mistake the user id
for an actual UID.
Test: Trivial refactoring no logical changes.

I didn't expect this to ever be hit, but apparently it is, so add
additional logging to track it down.

To make the transition to these new calls easier, give them a very
similar signature to MapUpdateSnapshot. Also, allow them to work in
non-compression mode.
