GWP-ASan can provide information about a crash that it caused. Grab the
GWP-ASan regions from the globals shared by the linker for crash-handler
purpopses, pull the information from GWP-ASan, and display it.
This adds two regions:
1. Causality tracking by GWP-ASan. We now print a cause header about
the crash, like `Cause: [GWP-ASan]: Use After Free on a 1-byte
allocation at 0x7365bb3ff8`
2. Allocation and deallocation stack traces.

Change metadata_cipher fstab option to metadata_encryption
that includes encryption flags in addition to the cipher.
wrappedkey_v0 encryption flag is used to denote that the
inline encryption hardware supports wrapped keys. dm-default-key
device is created and a wrappedkey is provided along with the
optional wrappedkey_v0 argument.

* changes:
add a version TXT record to adb secure mdns services
adbd: only register dnsservices via explicit API
adb client interface for secure services
get the ip address info for all DNS services
make the client browse for appropriate mdns services
Add mDNS services for pairing and connect
In the context of secure connect, allows adbd and host adb to reject
each other based on incompatible versions without even having to
actually connect (since it is a DNS TXT).

For privacy/security reasons, let's not broadcast the adb secure
services on startup automatically, and instead leave that up to
the rest of the adbd code somehow.
Instead, this CL adds an API in daemon/mdns.h that lets the user
control when registration happens, potentially only doing so if
the developer option is enabled or something.

This CL exposes a callback-based interface to perform some action for
each resolved pairing/connect service as a function of their hostname,
ip address, and port.
The ADB client can then use this information to either set up secure
connections directly, or to tell the adb host server to do so, or
something.

This CL adds functionality to the class ResolvedService where the ip
address associated with a resolved DNS service is recorded.
It also avoids connecting to the device unless it is the Things-related
DNS service.
Next step is to add some kind of interface in other parts of adb code
to retrieve these IP addresses.

but this should be useful to see if the right packet traffic for
discoverability is happening.

The SnapshotMergeStats class is issued by SnapshotManager to track the
merge duration and possible reboots during the merge process.

With the Virtual A/B feature, when the device successfully boots after an OTA
update, a dm-snapshot merge operation is performed, which consolidates the
updated images to the base devices. This merge operation depends on the OTA
size and may affect the device performance until completed.
Create the SnapshotMergeStats class that takes care of measuring the duration
of a merge operation and manages the merge state file to continue tracking the
merge in the case of an interruption due to a reboot.

To improve the test period for adb-remount-test.sh, if the device
fails to get to the launcher on the first try when wait_for_screen,
then print a warning to skip all later wait_for_screen conditions.
The wait_for_screen testing is really there to deal with first
confirming that the device is capable of getting to the launcher,
and that later tests that influence corners of adb remount behavior
do not result in a failure to get to the launcher screen. The
developer should look into ways to fix the failure to get to the
launcher on the first try, but failure to do so should have no
bearing on the remaining tests, so dropping the wait_for_screen
functionality is not an issue.

Because we cache file descriptors associated with cgroup "tasks" file it
should not be used with SetProcessProfiles API which operates on entire
processes rather than tasks. Change SetProcessProfiles API to prevent
cache fd usage, modify ExecuteForProcess to not attempt to use cached
fd. Also fix unconditional calls to EnableResourceCaching from
ExecuteForTask which should be called only when SetTaskProfiles is used
with use_fd_cache set to true.

When kernel lowmemorykiller driver is enabled lmkd detects it by
checking write access to /sys/module/lowmemorykiller/parameters/minfree
parameter. By default this file does not have write access and init
process changes that from "on boot" section of init.rc. However
"on boot" is never executed in the charger mode, therefore lmkd fails
to detect the kernel driver. Fix this by setting lowmemorykiller kernel
driver parameters before lmkd is started.
