Filesystems like ext4 allow the setting of the "resgid" parameter
to designate a GID that is allowed to use the "reserved" disk space
(in addition to UID 0). We'll be granting this GID to critical
system processes, so that the system is usable enough for the user
to free up disk space used by apps.

* changes:
tombstoned: add tests for b/36685795.
tombstoned: fix a race between intercept and crash_dump.
tombstoned: refactor request dequeuing a bit.
tombstoned: don't increment num_concurrent_dumps until success.
fs_mgr_avb_ops->read_from_partition() relies on the by-name prefix to
get the device file when reading a partition. Previously we store the
fstab struct and use fs_mgr_get_entry_for_mount_point() for every read.
It's better to do that once and store the by-name prefix for later use.

Add some tests for edge cases which may have triggered b/36685795.

Previously, there was no way to detect when tombstoned processed an
intercept request packet, making it possible for a intercept request
followed by a crash_dump being processed in the wrong order.
Add a response to intercept registration, to eliminate this race.

Also make it loop, so that upon failing to start a dequeued crash
request, we continue to the next one.

Change-Id: I94889125f16f4681c6fa0fa9cac456302602ce01
Previously, we would increment num_concurrent_dumps and fail to
decrement it if we failed to start the request. Change this to
only increment after we've successfully started the dump.

Use this for bootstat and init. This replaces the custom uptime parser in
bootstat.
This is a reland of aosp/338325 with a stubbed implementation for Darwin.
This change also has clang_format fixes (automatic).

get_hashtree_descriptor() currently restricts HASHTREE descriptor to be
either in /vbmeta or in the same partition for dm-verity setup.
Also allows it to be from /boot partition because the top-level vbmeta
might be appended at /boot in legacy devices without /vbmeta.
Bug: 35880930
Test: test AVB on bullhead with top-level vbmeta being at /boot

init used to block on installkey such that it was unable to
process property events. This lead to a deadlock by which
the Keymaster HAL would wait indefinitely for the
hwservicemanager.ready=true.
This fixes the issue by implementing the builtin in terms of
do_exec, which allows init to stay responsive to properties
while waiting for the child to terminate.
Bug: 36278706
Test: Add a 3s delay into hwservicemanager before it sets the property
hwservicemanager.ready and the device still boots.

- Processes capturing SIGTERM signal will not terminate and
killProcessGroup will timeout after retry. This gives 200ms
of waiting per such process. Change it to retry only once as
SIGTERM will keep failing for such process.
bug: 36696408
Test: check time spent in SIGTERM for reboot
Change-Id: I9b0843614598dd3f97a50b21352046297ed70b6b
- killProcessGroup retries if it fails while
killProcessGroupOnce only tries once.
- useful for sending signal like SIGTERM once.
bug: 36696408
Test: will add usage to init
