* changes:
init: Add support for native service registration with lmkd
lmkd: Support process types when registering a process
lmkd: Add library function to unregister a process
lmkd: Prepare lmkd to support connection from init process
lmkd: Restrict process record modifications to the client that created it
list system calls used for dumping code coverage information; empty on
non code coverage builds. Mini-jail configurations can include this file
instead of trying to manage the list themselves.
Bug: 139313557
Test: arm32/arm64/x86 media svcs w/native coverage on, kill -37 to dump stats.

From the implementation of FscryptInstallKeyring it looks like it will
install a new keyring on each call.
Another approach would be change FscryptInstallKeyring to first call
request_key[0] (http://man7.org/linux/man-pages/man2/request_key.2.html),
and don't add keyring in case request_key succeeded, but it looks like
that libkeyutils doesn't provide such functionality.
Since I was there, I've also added checks that we are not trying to
remount userdata on FDE devices.
Test: adb reboot userspace

Actually log results of adb commands, so we can see why this fails.
Fix the asan-detected use of a value from a reused part of the stack.
Test: atest FastDeployTest on Linux (with an asan adb)

Init unit tests refer to libraries that do not exist for the
secondary ABI, and we'd rather test the libraries on the device than
statically link them, so only test the primary ABI.
Init will only run on the primary ABI in any case, and doesn't have
much arch specific code in it.

Test: build

init should be able to register native services with lmkd so that they
can be killed when needed. Only processes with oom_score_adjust not
equal to the default -1000 will be registered with lmkd because with the
score that low the process is unkillable anyway.
Inform lmkd when a registered process is killed so that the record can be
removed.
Change init.rc to start lmkd during init phase so that it is there to
register other services.
Replace hardcoded oom_score_adj values with appropriate definitions.

Test: boot and verify native service registration

Add an optional process type field into lmkd registration protocol so that
applications can be distinguished from services.

Introduce lmkd_unregister_proc helper function. Fix a bug where
lmkd_pack_set_procremove used a wrong structure as a parameter.

Test: verify process record removal when it is manually killed

In order to register native services init needs ability to communicate with
lmkd. Make liblmkd_utils library available in recovery mode so that init
can link to it and add a data socket in lmkd to support additional
connection from init. Ensure SOCK_CLOEXEC type for lmkd socket to prevent
init children from inheriting it.

Associate each registered process with the PID of the lmkd client that
registered it to prevent one client from updating records of another
client.

Setting executable bit on system_ext/bin is missing, so add them into
list.

Test: m && check if system_ext/bin/* have execute permission.

This will bring device to the state closer to the one during normal boot
