I find myself using something like this every time I add functionality
to init. I cannot possibly be the only one doing this. On the other
hand, if this hasn't been added for so long, maybe there's a reason
for that.
The advantage of using a test service versus modifying an existing
service is that the test service doesn't *require* any permissions or
privileges, so you can add and/or remove whatever you need to test
without breaking the service.
I found it useful to have the service check its own /proc/<pid>/status
from command-line arguments, so that's what the service does.
This CL also adds a .clang-format file for init.
Bug: None
Test: Service runs and exits successfully.

There are many use cases from vendors to exec service in background and then
use a shell scriprt to wait for the command done.
This CL is to add a wait_for_prop command to suppor those use cases.

external/avb/libavb provides the new Android Verified Boot (AVB) flow.
It has different verity metadata format than previous formats in
fs_mgr_verity.cpp fs_mgr should support using libavb to read the metadata
(a.k.a. HASHTREE descriptor in AVB) to enable dm-verity in kernel.
Two important files in this commit:
- fs_mgr_avb_ops.c: an implementation of struct AvbOps* for libavb to do
platform dependent I/O operations, e.g., read_from_partition.
- fs_mgr_avb.cpp: it reads the metadata (a.k.a. vbmeta images in AVB) from
all partitions, verifies its integrity against the values of
androidboot.vbmeta.{hash_alg, size, digest} passed from bootloader in
kernel command line. Then enable dm-verity for partitions having the
corresponding HASHTREE descriptor and with an 'avb' fstab flag.
Bug: 31264231
Test: Enable dm-verity on /system partition

tkill and tgkill are syscalls that do not have glibc wrappers, but
they are required in order to send a signal to a specific thread.
Non-android software may call them directly with syscall(). Bionic
provides a wrapper for tgkill, so seccomp allows it, but not for
tkill. Add tkill to the whitelist.
This can be reproduced with:
sleep 1000 & sleep 1 ; strace -p $!
then hit ctrl-C, and the shell will print "Bad system call" because
the strace process died with SIGSYS

restart_syscall is used by the kernel whenever a syscall with a
timeout is interrupted. Whitelist it in seccomp to prevent

The following files will be loaded additionally.
- /odm/default.prop and /vendor/default.prop for default props.
- /odm/build.prop for build props.
The props files must follow the following priority order.
- /default.prop > /odm/default.prop > /vendor/default.prop
- /system/build.prop > /odm/build.prop > /vendor/buid.prop
Test: tested default/build prop files with enabling early mount, but
didn't test files of odm partition because odm partition doesn't
exist now.

This now combines all the "libsparse" libraries into the same soong
target. A minor side-effect of this change is that the libsparse
static library depends on the libz shared library instead of the libz
static library. This minor change has no effect since targets using
the static libsparse library need to explicitly include either the
static libz or the shared one.
