init: allow entering of network namespaces
Add the ability to enter a network namespace when launching a service.
Typical usage of this would be something similar to the below:
on fs
exec ip netns add namespace_name
service vendor_something /vendor/...
capabilities <lower than root>
user not_root
enter_namespace net /mnt/.../namespace_name
Note changes to the `ip` tool are needed to create the namespace in
the correct directory.

init: support setting rlimits per service
Add a new service option, `rlimit` that allows a given rlimit to be
set for a specific service instead of globally.
Use the same parsing, now allowing text such as 'cpu' or 'rtprio'
instead of relying on the enum value for the `setrlimit` builtin
command as well.
Bug: 63882119
Bug: 64894637
Test: boot bullhead, run a test app that attempts to set its rtprio to
95, see that the priority set fails normally but passes when
`rlimit rtprio 99 99` is used as its service option.
See that this fails when `rlimit rtprio 50 50` is used as well.

init: Add readahead built-in command
Inspired by ag/2659809/, this CL add readahead built-in command in init
to let files be prefetched into pagecache for faster reading.
Readahead happens in background but due to filesystem limitation it
might take small amount of time in it reading the filesystem metadata
needed to locate the requested blocks. So the command is executed in a
forked process to not block init execution.

add "shutdown critical" to service
- "shutdown critical" prevents killing the service during
shutdown. And the service will be started if not running.
- Without it, services will be killed by SIGTERM / SIGKILL during shutdown.
- Even services with "shutdown critical" will be killed if shutdown
times out.
- Removes ueventd and vold from hard coded list. Each service's rc will
be updated to add "shutdown critical". watchdogd is still kept in the list.

init: Stop combining actions
In the past, I had thought it didn't make sense to have multiple
Action classes with identical triggers within ActionManager::actions_,
and opted to instead combine these into a single action. In theory,
it should reduce memory overhead as only one copy of the triggers
needs to be stored.
In practice, this ends up not being a good idea.
Most importantly, given a file with the below three sections in this
same order:
on boot
setprop a b
on boot && property:true=true
setprop c d
on boot
setprop e f
Assuming that property 'true' == 'true', when the `boot` event
happens, the order of the setprop commands will actually be:
setprop a b
setprop e f
setprop c d
instead of the more intuitive order of:
setprop a b
setprop c d
setprop e f
This is a mistake and this CL fixes it. It also documents this order.
Secondly, with a given 'Action' now spanning multiple files, in order
to keep track of which file a command is run from, the 'Command'
itself needs to store this. Ironically to the original intention,
this increases total ram usage. This change now only stores the file
name in each 'Action' instead of each 'Command'. All in all this is a
negligible trade off of ram usage.
Thirdly, this requires a bunch of extra code and assumptions that
don't help anything else. In particular it forces to keep property triggers
sorted for easy comparison, which I'm using an std::map for currently,
but that is not the best data structure to contain them.
Lastly, I added the filename and line number to the 'processing
action' LOG(INFO) message.
Test: Boot bullhead, observe above changes
Test: Boot sailfish, observe no change in boot time

init: handle sys.powerctl immediately
Currently if a process sets the sys.powerctl property, init adds this
property change into the event queue, just like any other property.
The actual logic to shutdown the device is not executed until init
gets to the action associated with the property change.
This is bad for multiple reasons, but explicitly causes deadlock in
the follow scenario:
A service is started with `exec` or `exec_start`
The same service sets sys.powerctl indicating to the system to
shutdown
The same service then waits infinitely
In this case, init doesn't process any further commands until the exec
service completes, including the command to reboot the device.
This change causes init to immediately handle sys.powerctl and reboot
the device regardless of the state of the event queue, wait for exec,
or wait for property conditions.

init: add exec_start command
Exec services may also want to set other service flags such as
priority. Instead of expanding the exec syntax to handle this, create
a new command, exec_start, that will treat an existing service
definition as an exec service. The new exec_start command will start
the service then halt init from executing further commands until the
service has exited.
This change additionally encapsulates the waiting_for_exec logic into
ServiceManager and removes the ambiguous 'bool' return value from
Reap() which previously indicated if a Reaped service was an exec
service or not.

Add 'ro.cpuset.default' system property for default cpusets.
Normally 'writepid' is used to add a process to a particular cpuset. However
certain systems with big/small cores might need to specify a default cpuset for
system processes which do not explicitly specify one. Add an option to use
'ro.cpuset.default' system property to specify default cpuset for system processes
which do not explicitly write to /dev/cpuset/... with 'writepid' option.
The cpuset name specified in ro.cpuset.default is just the cpuset name, e.g.
'/system-background', '/foreground', or simply '/' for the "root" cpuset.
Bug: 28550814
Test: `m -j32` succeeds for aosp_sailfish-eng. Phone boots successfully.
Also tested manually with debug trace messages on emulator with different
combinations of values for 'ro.cpuset.default'.
