dev.mnt. properties are primarily intended for tuning parameters for
mounts such as /system and /data but don't have much use for emulated
mounts.
There are additional emulated mounts created for each user on a
device, so if too many users are created, init would otherwise create
too many dev.mnt. properties, filling the property file that backs
these properties, and preventing more properties from being
generated.
Therefore, this change stops init from creating dev.mnt. properties
for emulated mounts.

Integrate Snapuserd daemon with libsnapshot library and handle
IO requests from dm-snap and dm-snap-persistent.
Tested all the 3 COW operations on a compressed
cow-device file generated through vab_converter_payload.

Test: Added test case to independently test snapuserd IO path.
Manual test on compressed cow file generated and verifying
md5sum.

Remove a few tests that require logd to implement chatty to not
require chatty to pass CTS. Note that these tests are already removed
in AOSP and won't be required in S.

Previously ClearUidLogs() would Compress() the log buffer in all
cases, however that is the wrong behavior when writer_active_ is true
and would leave the SerializedLogChunk object in an invalid state. If
more logs are written to the log, then write_offset() will be higher
than the compressed size of the log, violating a CHECK() when later
decompressing the log.
This change does not call Compress() in ClearUidLogs() if
writer_active_ is true. It upgrades a check in Compress() from a
simple if statement to a CHECK() to prevent against this happening in
the future.
It adds a test that exercises the previously failing path.

Previously, when push --sync was used with multiple files, we tried to
stat a remote file with pending acknowledgements still in the socket
buffer, which leads to an abort when we read ID_OKAY instead of the
response we were expecting.
This patch changes the behavior to always wait for acknowledgements if
we're pushing with --sync (or `adb sync`). This results in a ~100ms
regression during a 10 second sync of every file on the system image,
but that's not very much, so perhaps we should consider doing this
always.

This tool allows users to estimate the COW size for a non-A/B update.
It works by scanning the partitions of two target-files packages, and
identifying moved or copied blocks, and simulating the impact in the new
COW format.
It has two modes:
estimate_cow_from_non_ab_ota -ota_tf <path>
Will estimate the COW size for a full OTA. For an incremental OTA, you
need two target files packages:
estimate_cow_from_non_ab_ota -source_tf <path> -ota_tf <path>
There is an optional -compression argument which accepts either "none"
or "gz".

We are porting cuttlefish to Android, it currently uses libsparse to
desparse Android filesystems to be used directly as disk images by
crosvm. Making this library available to 'vendor' enables us to support
desparsing downloaded images on-device as well.

The input code is the only customer of PropertyMap. For easier
maintenance and eventual removal of it, move it to libinput.
Currently, the caller is responsible for managing the lifecycle of the
returned outMap when calling PropertyMap::load. However, the fact that
the function call allocates new memory is not obvious from the function
signature.
In a separate commit, I will refactor the function to return
Result<unique_ptr<>> to make it less errorprone.
In this commit, only move the files around to make code reviews easier.

1) `logcat -g` now contains 'readable', so fix sscanf() appropriately
2) Remove tests that the security buffer isn't returned as an error,
since it's not important to hide this buffer from the logging front
end, and more importantly: the expected failures no longer happen.
3) Update invalid_buffer for the new error format.
