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.

Move lastTid array from local in LogBuffer::flushTo to per-reader
context in LogTimes::mLastTid and pass into LogBuffer::flushTo.
Replace NULL with nullptr in touched files.
Simplify LogTimeEntry::cleanSkip_Locked initialization of skipAhead
to memset, to match mLastTid memset initialization.

Failed to acquire BM_log_print_overhead as it was renamed from
BM_log_overhead in commit 8f2492f582
(liblog: benchmark: Use local LOGGER_NULL frontend')
The test report would not clearly identify which entry was missing, or
unparsed, so unrolled the loop and incorporating the indexes by name
so that gTest failure report offers a much better clue to the problem.

This code was supposed to be deprecated in time. Let's make it more
efficient and add QC_RIL prefix to the list of catches to redirect
from the main logs to the radio logs.

* 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.

Test: debuggerd_test
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

For dynamic linking perspective, semantics of NativeBridge needs to
align with dynamic linker. This patch adds "linked namespace" semantic
which shares some libraries from one namespace to another.

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.

Test: check time spent in SIGTERM for reboot
