Mount a tmpfs on top of it, and serve as a mirror of /data/data
and /data/user_de, which will be used when zygote forks and
overlay its CE and DE storage to prevent app can see other applications.
Also, changed /data/user/0 from symlink to bind mount, so
/data_mirror/data_ce/null can just bind to /data/user directly.

The MS OS extended property descriptor is used to convey additional
information to Windows hosts, in this case the DeviceInterfaceGUID
which allows the inbox WinUSB driver to get automatically installed.
However, the ADB windows client looks for USB devices by enumerating
devices with a specific GUID {F72FE0D4-CBCB-407D-8814-9ED673D0DD6B},
and as a result fails to find the device since it was installed with
a different DeviceInterfaceGUID. Update the OS descriptor to pass
back the same GUID the client already uses.

This splits fs_mgr_overlayfs_scratch_device into two new methods. The
first, GetScratchStrategy, returns an enum detailing exactly how the
device will find space for scratch:
- via system_<other>,
- via super_<other>, or
- via a dynamic partition.
The second method, GetScratchDevice, uses the strategy to either return
the underlying block device, or look up a dynamic partition.
fs_mgr_overlayfs_scratch_device will be removed completely in a separate
patch.

This code was introduced to help performance by skipping sending these
messages to logd when logd would later drop them. However it has
multiple flaws:
1) Event logs aren't super common and non-loggable event logs are even
less common, so it would be a trivial benefit if any.
2) This code is not particularly safe as written, which is even
acknowledged in the comments.
3) This forces processes that write event logs to allocate a rather
sizable amount of memory.
Therefore, it's better to simply remove this and let logd drop these
messages when it receives them.

The previous code would lazily check for 'exact' and accept any other
value as a prefix match. This should be a tighter check allowing only
'exact', 'prefix', or an empty string for this option.
Test: build fails if an invalid string is used for the match operation
Test: build succeeds normally
Test: `getprop -Z` shows exact vs prefix is differentiated correctly

This still fakes the long removed /dev/log devices, whereas it only
needs to print to stderr, so simplify that code.
Use std::mutex now that it is C++ to easy portability concerns.
Use the proper liblog headers for formatting information instead of
hardcoding a copy.

Previously the AVB public keys for DSU is hard coded for each key path.
This adds the burden for maintaining the codebase, e.g., need to change
avb_keys each time when any new key is added or some old key is deleted.
With commit Ie74845d8c8e4aa45e8a9e3b862424cec641f8090, it's possible to
load avb keys from a directory. Let's use "/avb" for DSU AVB keys.
Also removing fstab entries that specifying vbmeta_partition. The AVB
keys used in DSU flow should be a separate set from the original
vbmeta.img (or vbmeta_system.img).

The ipt_ULOG.h file has been deprecated, so it's being removed from
the bionic uapi kernel headers. Since this is the only code that
is using that file, copy the one structure needed to parse one type
of message into the file that needs it.

This should solve the problem of
`property:sys.usb.config=adb && property:sys.usb.configfs=0` action
being wrongly triggered during userspace reboot.
Also reset some adbd-related property in `on userspace-reboot-requested`
action to make sure that userspace reboot sequence is as close as
possible to normal boot sequence w.r.t adbd.
Test: adb reboot userspace
Test: checked property:sys.usb.config=adb && property:sys.usb.configfs=0
action is not triggered
