This commit removes the soname filter from the namespace fallback link
from `runtime` to `system` in the vendor process. This fixes the
problem that vendor process might fail to load `libnetd_client.so`,
`libc_malloc_debug.so`, `libc_malloc_debug_leak.so`, and other libc
dependencies.
This commit also removes the namespace fallback link from `runtime` to
`default` in the vendor process. According to the comments in [1], the
original intention was to allow the access to `/system/${LIB}` not
`/vendor/${LIB}`. Furthermore, `com.android.runtime` suppose to work
without libraries from `/vendor/${LIB}`.

A zombie setsid process occurs when adb shell setsid <command> is
issued, however llkd can only detect if it is a result of a kernel
livelock by killing the associated parent, which would be adbd;
resulting in the adb connection(s) being terminated. Will special
case this condition in order to preserve adbd for debugging purposes.
We parse <parent>&<child> in ro.llk.blacklist.parent as this
association, thus adbd&[setsid] covers this special case.
Ampersand was selected because it is never part of a process name,
however a setprop in the shell requires it to be escaped or quoted;
init rc file where this is normally specified does not have issue.
getComm() is effectively pure, so hold on to the return value for
sake of efficiency.
This also reverts commit 599958d114
which granted adbd blanket parent immunity from monitoring on
userdebug builds. The new logic is a more refined means of
preserving the live lock checking associated with adbd and allows
the operation to be performed on user builds.

Because of the limited length of properties, and to ease the
complexity of product and vendor adjustments, the comma separated
list properties will use a leading comma to preserve the defaults
and add or subtract entries with + and - prefixes respectively.
Without the leading comma, the list is explicitly specified as before.
Cleanup:
- use empty() instead of space() == 0 (or converse if != 0)
- if (unlikely) pprocp can not be allocated, to a to_string(ppid) check
For testing, observe before and after llkd_unit_test below to
confirm leading comma effects for example:
livelock: ro.llk.stack=wait_on_page_bit_killable,bit_wait_io,\
__get_user_pages,cma_alloc
livelock: ro.llk.stack=...,SyS_openat,...

Adjusted debugging messaging to add clarity. Report _which_ stack
signature matched that triggered the kernel panic. Reduce the noise
associated with missing /stack to VERBOSE as that is for development
debugging only.
Test: observe during unit test we see something like following logs:
livelock: Found SyS_openat in stack for pid XXX
livelock: S 120.000s XXX->YYY port-bridge [kill]
livelock: Killing '/vendor/bin/port-bridge' (XXX) to check forward\
scheduling progress in S state for\

platform/interfaces/health/2.0/default/healthd_common.cpp wants to use
timerfd_create() to register a wakealarm.
To use the timerfd_create() syscall with CLOCK_BOOTTIME_ALARM,
CAP_WAKE_ALARM is needed.
Since the .rc file for android.hardware.health@2.0 is shipped here in
system/core, update it here.

Currently vbmeta images are stored in AvbSlotVerifyData defined in
libavb, which contains some fields that isn't needed by fs_mgr.

This commit adds the fundamental test framework for the upcoming
changes in libfs_avb. It replies on 'avbtool' to append AVB
metadata and then extracts the vbmeta content into an internal
|vbmeta_images_| variable for comparison later.

This is a workaround to allow us to use libnetd_resolv.so from
the resolver APEX before b/120661824 is fixed.
We cannot put the APEX into the search path due to b/120661824,
but we can put it into the permitted path,
