unit tests
1, Previous implementation has the staged prop application done in
property_service, which caused a number of unnecessary changes which
including exposing apis like AddPersistentProperty. In addition, it made
the property_service logic complicated. A better design is to have the
staged value application done while reading the persistent properties
from file. This way, no change to property service. In addition, unit
test is much cleaner and efficient.
2, add a unit test to lock down the behavior. Specifically, it locks down that when a prop is staged, it should be applied the next time when the persistent prop is loaded. In addition, it should lock down that other persistent props are not overwritten.

The max_processes calculation is incorrect for KillProcessGroup because
the set of processes in cgroup.procs can differ between the multiple
reads in the implementation. Luckily the exact value isn't very
important because it's just logged. Remove max_processes from the API
and remove the warning about the new behavior in Android 11.
Note that we still always LOG(INFO) that any cgroup is being killed.

This fixes a bug introduced by I81b6bd984aad8f7ddec93ce74f4543e4f71be508
In the original CL, setting a sysprop `next_boot.<name>` and then
rebooting the device could remove all the persistent properties stored
in /data/property/persistent_properties. It happened because the
function `WritePersistentProperty` is called with a properties set which
is initialized as an empty set and then added with the properties which
had the next_boot prefix.
As a result...
Before the boot:
* persist.a = 1
* next_boot.b = 2
* next_boot.persist.c = 3
After the reboot:
* b = 2
* persist.c = 3
persist.a gets lost.
This change fixes the issue by populating properties set from the memory
and then save it to the file.

create_apex_data_dirs() now uses GetApexListFrom(dir) in
apex_init_util.cpp.
This is essentially a refactoring, but there are a few behavioral
changes, which I think make more sense.
- Emits no error when opendir(/apex) fails.
- Emits errors when mkdir fails for each apex.
- Does not abort `perform_apex_config` even though create_apex_data_dirs
fails.

Reading .rc files from bootstrap APEXes causes "double loading".
This works for services because init just ignores duplicates. But it
emits error logs, which can mislead even though there's no actual
errors. Besides, for actions, duplicates can cause a problem when
commands are not idempotent.
So, when loading RC files from APEXes for the second time, we'd better
skip those bootstrap APEXes.

To start an early_hal service from a bootstrap vendor apex, init now
reads .rc files from bootstrap apexes as well.
In this change, perform_apex_config command is re-purposed to support
bootstrap mode. Now we have some similarity between two apexd calls:
- for bootstrap apexes (in the bootstrap mount namespace):
exec_start apexd-bootstrap
perform_apex_config --bootstrap
- for normal apexes (in the default mount namespace):
restart apexd
...
wait_for_prop apexd.status activated
perform_apex_config
Note that some tasks in perform_apex_config are not needed in the
bootstrap. For example, we don't need to create apexdata directories
for bootstrap apexes.

Right now there are two bootconfig parsers that gets linked into `init`.
One is from libinit itself and the other is from libfs_mgr.
The one in libinit removes all space characters between list elements,
so `key = "val1", "val2"` gets unquoted and squeezed into:
`key=val1,val2`
The one in libfs_mgr doesn't remove spaces, it only unquotes:
`key=val1, val2`
The libinit behavior is due to existing systems (such as sysprop)
expect the config value to be in the same format as kernel cmdline.
(aosp/1757971)
THe libfs_mgr behavior is due to the `androidboot.boot_device[s]`
format explicitly allows quoted comma appear in its list value, thus
relies on space, not comma, as the list value delimeter.
This commit merges the two parsers into libfs_mgr. Since all usages in
libfs_mgr besides `boot_device[s]` do not care about how list value are
delimited, and most usages in init expects the bootconfig value format
to be the same format as cmdline. We just special case the
`boot_device` scenario.
Also harden the test cases to cover all the different config value
format and expected result.
Note:
The format of kernel bootconfig is described here
