Add SE Android support for init and ueventd.
init:
- Load policy at boot.
- Set the security context for service daemons and their sockets.
- New built-in commands: setcon, setenforce, restorecon, setsebool.
- New option for services: seclabel.
ueventd:
- Set the security context for device directories and nodes.

Creating a root owned /data/local.prop is one of the most common
ways to root an Android device. /data/local.prop is only intended
to assist developers on debuggable devices, and is never
intended to be used on production devices.

If we process the import directive inline, then the ordering of the
commands for the "on xxx" sections would be a little unexpected. The
init.rc files do not really have an implied order as to which section
appears and gets processed first. The init code itself provides that
ordering explicitly. For the user, the expectation is that if both the
current file and the imported file define a section (e.g. "on init"),
then the commands in the current file will be executed first, and then
the ones from the imported file(s).
The current implementation did not do that. It processed the import
directive inline, and thus the imported (i.e. dependent) files would
appear first in the command lists for the sections. This created
unintended side effects and the solution would have been to try and
put the import lines somewhere in the middle of the init file. This
would be difficult to notice and hard to extract the dependencies.
To solve this, we add the imports to a list for each file being parsed
and process the list after finishing parsing the file. This provides
predictable order for imports and provides a logical flow from the
user perspective: the currently parsed file gets to run its commands
before the files being imported.

Also, clean up how we initialize the ro.xx properties and process
the kernel command line.

This removes the hardcoding of the file import in init and instead
allows the init.rc file to fully control what is loaded.

Adds new property syntax in init files during init file filename
expansion during the import command:
${prop.name}
So, one can do: import /init.${ro.hardware}.usb.rc
Should convert other usages of property names to use the new function.

The property service is still started later, but the property area
and the initial boot properties are initialized before the init.rc
file is processed. This allows init.rc files to have access to boot
properties during parsing.

The class_reset command used to reset services that had been set to
"disabled" in the init.rc file to a non-disabled state. Now, if the
service was originally set to "disabled", have the reset command set
it back to disabled. Otherwise, set it to the "reset" state as it
currently does.

Introduces a 'charger' section that is processed when androidboot.mode
supplied on the kernel commandline is "charger".
In this mode, sections such as fs, post-fs, etc are skipped. Only the
'early-init' and 'init' sections of the init rc files are processed before
processing the 'charger' section.

Besides, profiles are now stored and encrypted by keystore.

For example, the following trigger will fire when the sys.foo property
is set to any value:
on property:sys.foo=*
write /data/foo hello
It is also possible to refer to the property within the trigger actions:
on property:sys.foo=*
write /data/foo $sys.foo

The write command will write a property value if the value starts with a "$'
For example:
write /sys/class/android_usb/iSerial $ro.serialno
Use double leading '$' if you need to write a string that starts with '$':
write /data/foo $$hello
to write "$hello" to /data/foo
