bbcbc2ffb3 init: replace Result<Success> with Result<void>
Now that Result<T> is actually expected<T, ...>, and the expected
proposal states expected<void, ...> as the way to indicate an expected
object that returns either successfully with no object or an error,
let's move init's Result<Success> to the preferred Result<void>.

c240440eec init parses *.rc files from APEXes
Init now parses *.rc files from the APEXs when the apexd notifies the
mount event via apexd.status sysprop.

Test: m apex.test; adb root; adb push <builtfile> /data/apex; adb reboot
adb root; adb shell setprop ctl.start apex.test; dmesg shows that init
tries to start the service which doesn't exist.

d72432de93 Don't check permissions bits on init scripts for host_init_verifier
Also get rid of the copy in parser.  There's no incentive to switch to
a tokenizer that doesn't modify the input, nor is there a reason to
waste cycles making a copy of every init script as its processed.

194b5d1da9 init: handle properties and imports for host init verifier
Allow specifying properties on the command line when running host init
verifier.  This is needed particularly for importing files that have a
property expansion in their path.

Handle the import statement on host, basing paths off of the out
directory of Android builds.

de6bd50d42 init: add host side parser for init
Create a host side parser for init such that init rc files can be
verified for syntax correctness before being used on the device.

Allow it to fail. When there is an error for a section ending,
print the error pointing to the line where the section starts.

67dee626e0 init: remove Parser singleton and related cleanup
* Remove the Parser singleton (Hooray!)
* Rename parser.* to tokenizer.* as this is actually a tokenizer
* Rename init_parser.* to parser.* as this is a generic parser
* Move contents of init_parser_test.cpp to service_test.cpp as this
  actually is a test of the parsing in MakeExecOneshotService() and
  nothing related to (init_)parser.cpp

ad6741c6f8 init: remove unused parts of parser.cpp
Now that ueventd is using init's parser, we no longer need anything
other than the tokenizer from parser.cpp.

304f12270d init: delay importing files until after parsing the current file
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.
