The initramfs.img from kernel builds do not store kernel modules under

modules from _16k dir if running on 16K page size kernel. Relax this

do_start() ignores ENOENT intentionally to avoid logspam. It's
implemented in ErrorIgnoreEnoent. However, without resetting errno,
ErrorIgnoreEnoent will ignore unrelated errors from Service::Start() due
to the sticking errono set from other commands.

ServiceList's services_update_finished flag was overlapped with the
global flag: is_default_mount_namespace_ready. Now DelayService() relies
on the is_default_mount_namespace_ready flag.
Add a service description with 'updatable' flag and invoke 'start
<name>' in 'on init' block (which comes before APEX activation).

don't always exist, so don't call selinux_android_restorecon() on them
when they don't exist. This eliminates the following error messages:

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

init and libfs_mgr both defines get_android_dt_dir() with subtle
differences. Merge the two implementations into libfs_mgr to reduce code
duplication (in terms of source code and code gen)
Note:
init's implementation checks the kernel cmdline first and then the
kernel bootconfig, while libfs_mgr's order is the opposite.
Realistically I don't think this order matter much though. If any, we
should prioritize bootconfig over kernel cmdline most of the time.

This new directory is bind-mounted to /apex in the bootstrap mount
namespace so that apexd-bootstrap mounts bootstrap APEXes there via
/apex.
The directory is detached from /apex in the default mount namespace but
still visible in case bootstrap APEXes are needed.
However, there are (mostly, virtual) devices which don't need two mount
namespaces. Those devices don't need to make /bootstrap-apex directory
at all.

MarkServicesUpdate() starts delayed services which are mostly for
APEXes. (e.g. start a service from APEX). But before
"DefaultNamespaceReady", services are started in "bootstrap" mount
namespace, which makes services from non-bootstrap APEXes fail to start.
This is a quick fix for the problem before coming up with better
solution in the future.

The existing approach in first_stage_init/first_stage_mount makes it
harder to add conditional logic that should only be applied for
Microdroid. Additionally, it forces the FirstStageMount object to be
created twice.
This change refactors the control flow to make first_stage_init take the
ownership of the FirstStageMount object. It will help with the follow up
change (which will add logic to conditionally mount /vendor partition
while booting Microdroid). As a nice side effect, this refactoring also
fixes the problem of the FirstStageMount being created twice.
This change also merges the FirstStageMount and FirstStageMountVBootV2
in a single class, since nobody actually uses FirstStageMount.
