Elliott Hughes e18e7e5c43 Improve init Service logging.
Say which service.

Don't ignore setpgid failures.

Jorge Lucangeli Obes 344d01f99f Refactor Service::Start method.
This CL extracts code from Service::Start into four helper functions,
bringing Service::Start down to 134 lines vs 212 lines originally. This
makes the method a lot easier to follow. There is no change in behaviour.

Also, make error messages consistent (start with lowercase) and
format Service::Start to fit in 100 cols.

Jorge Lucangeli Obes 177b27d4f5 Rename "Handle(r)" to "Parse(r)" in Android init.
The code in question parses config files, so use the right terminology.

Jorge Lucangeli Obes 1b3fa3d650 init: Add option to run a service in a new PID/mount namespace.
Namespaces are a more consistent isolation primitive than e.g. hiding
/proc.

Elliott Hughes ad8e94e017 init: report createProcessGroup failure.
Also directly kill the initial pid for safety, like other libprocessgroup
users.

Tom Cherry bac3536cc9 init: expand arguments of services when they start
Arguments of commands are expanded based on properties if they contain
${property.name}, however this is not currently done for arguments of
services.

This patch makes it that arguments of services are expanded each time
that the service starts at the point immediately before execve().

Collin Mulliner f7e79b99c1 use process groups for processes started by init
Put every service into a process group, kill the process group
and all child processes created within the group when killing the
service. Removed libutil dependency in libprocessgroup.

Viorel Suman 70daa67062 Multiple consoles
This CL allows enabling of multiple consoles. A service can be
mapped to a specific console by providing the optional argument,
IE "tty0", to "console" service attribute as follows:

service fbconsole /system/bin/sh
    class core
    console tty0
    disabled
    user shell
    group shell log readproc
    seclabel u:r:shell:s0

Anestis Bechtsoudis b702b46f68 init: fix writepid wrong pid written in file(s)
When child (pid==0) executes fork branch 'pid_str'
will always be 0 writting wrong value to file(s).
Fix by utilizing getpid() to obtain correct pid.

Tracker link provides some insight on why use cases
aren't broken.

Bertrand SIMONNET b7e03e82b8 init: Allows shutting down cleanly.
When ro.build.shutdown_timeout is set, init will send a SIGTERM signal to
all services on reboot. The normal shutdown process will continue once
all services have exited or after the shutdown timeout
(ro.build.shutdown_timeout).

If ro.build.shutdown_timeout is not set, we assume a 0s timeout.

Bug: 26216447
Test: manual: Ask to reboot. All services exit cleanly.

Tom Cherry 1563d6546c Remove property_area_initialized
This is deadcode as property_init() will only ever be called once and
the only remaining caller of properties_initialized() is
Service::NotifyStateChange() which can only be called after properties
have been initialized.

Tom Cherry b7349902a9 init: Use classes for parsing and clean up memory allocations
Create a Parser class that uses multiple SectionParser interfaces to
handle parsing the different sections of an init rc.

Create an ActionParser and ServiceParser that implement SectionParser
and parse the sections corresponding to Action and Service
classes.

Remove the legacy keyword structure and replace it with std::map's
that map keyword -> (minimum args, maximum args, function pointer) for
Commands and Service Options.

Create an ImportParser that implements SectionParser and handles the
import 'section'.

Clean up the unsafe memory handling of the Action class by using
std::unique_ptr.
