Any service which is executed when Runtime apex is mounted, but
linkerconfig is not updated can fail to be executed due to missing
information in ld.config.txt. This change updates init to have a status
variable which contains if current mount namespace is default
and APEX is not ready from ld.config.txt, and use bootstrap namespace if
it is not ready.

cleanly, the output of the default fstab and /proc/mounts, and
a list of mounts which failed to unmount. This information is only

everything unmounted, even if some services failed to stop).

Currently the ReadDefaultFstab function, which calls GetFstabPath,
makes some assumptions about what the fstab will be called and where
it is located. This is being used by vold to set up userdata encryption
and for gsid, and is even used in the default boot control HAL, so it
has become quite baked.
The original way for a board to specify things to mount was to use the
"mount_all /path/to/fstab" command in init.rc. However, due to the
above functionality, the path after mount_all is no longer very useful,
as it cannot differ from the inferred path, or userdata encryption and
other features will be broken.
On Cuttlefish, we have an interest in being able to test alternative
userdata configurations (ext4 vs f2fs, encryption on/off, etc.) and
currently the only way to achieve this is to either a) modify the
ro.hardware or ro.hardware.platform properties, which breaks a bunch
of things like default HAL filenames, or regenerate our odm.img or
vendor.img filesystems. We can't simply install another fstab and
point to it with "mount_all".
This change allows the fstab path to be omitted from "mount_all", and
adds another property which overrides the existing checks for
fstab.${ro.hardware} and fstab.${ro.hardware.platform}. Specifying
${ro.boot.fstab_suffix} will cause fstab.${ro.boot.fstab_suffix}
to be checked first.

A previous change moved property_service into its own thread, since
there was otherwise a deadlock whenever a process called by init would
try to set a property. This new thread, however, would send a message
via a blocking socket to init for each property that it received,
since init may need to take action depending on which property it is.
Unfortunately, this means that the deadlock is still possible, the
only difference is the socket's buffer must be filled before init deadlocks.
There are possible partial solutions here: the socket's buffer may be
increased or property_service may only send messages for the
properties that init will take action on, however all of these
solutions still lead to eventual deadlock. The only complete solution
is to handle these messages asynchronously.
This change, therefore, adds the following:
1) A lock for instructing init to reboot
2) A lock for waiting on properties
3) A lock for queueing new properties
4) A lock for any actions with ServiceList or any Services, enforced
through thread annotations, particularly since this code was not
designed with the intention of being multi-threaded.

There are two namespaces from init - bootstrap and default - and those

namespace, and re-generate linker config after APEX mount from each
namespaces.

This creates the directory /data/misc/apexdata, at the same time as other
directories under /data/misc. Then, when apexd has finished activating
APEXes, a directory is created under /data/misc/apexdata for every
APEX, with the same name as the APEX module name.
See go/apex-data-directories.
APEXes are discovered by scanning the /apex directory. It may be better
to delegate this process to a library, but it is proposed to defer that

Init is no longer a special case and talks to property service just
like every other client, therefore move it away from property_set()
and to android::base::SetProperty().

This makes the responsibilities between init and property services
more clear.

Previously, we assumed that TriggerShutdown() should never be called
from vendor_init and used property service as a back up in case it
ever did. We have since then found out that vendor_init may indeed
call TriggerShutdown() and we want to make it just as strict as it is
in init, wherein it will immediately start the shutdown sequence
without executing any further commands.

From the implementation of FscryptInstallKeyring it looks like it will
install a new keyring on each call.
Another approach would be change FscryptInstallKeyring to first call
request_key[0] (http://man7.org/linux/man-pages/man2/request_key.2.html),
and don't add keyring in case request_key succeeded, but it looks like
that libkeyutils doesn't provide such functionality.

Especially now that property_service is a thread, there may be some
delay between when init sets sys.powerctl and when the main thread of
init receives this and triggers shutdown. It's possible that
outstanding init commands are run during this gap and that is not
desirable.
Instead, have builtins call TriggerShutdown() directly, so we can be
sure that the next action that init runs will be to shutdown the
device.

This replaces the recently added `exec_reboot_on_failure` builtin, since

This is in line with what we decided when adding `exec_start` instead
of extending `exec` to add parameters for priority.
Test: `exec_start` a service with a reboot_on_failure option and watch
the system reboot appropriately when the service is not found and when
the service terminates with a non-zero exit code.

It's been a long standing issue that init cannot respond to property
set messages when it is running a builtin command. This is
particularly problematic when the commands involve IPC to vold or
other daemons, as it prevents them from being able to set properties.
This change has init run property service in a thread, which
eliminates the above issue.
This change may also serve as a starting block to running property
service in an entirely different process to better isolate init from
handling property requests.
Reland: during reboot, init stops processing property_changed messages
from property service, since it will not act on these anyway. This
had an unexpected effect of causing future property_set calls to block
indefinitely, since the buffer between init and property_service was
filling up and the send() call from property_service would then
block. This change has init tell property_service to stop sending it
property_changed messages once reboot begins.
