Add IntentFilter auto verification - part 3

- add private API PackageManager.getAllIntentFilters(String)
for getting all IntentFilters from a given package
- update IntentFilterVerificationInfo to use an ArrayList<String>
for domains instead of a String[]
- if you make an App a default domain handler then make the
others as non default
- create an IntentVerificationInfo even if the App IntentFilters
do not need to be verified. This would be done only if the App
has some domain URLs defined and would allow to make it the
default handler for a domain
- a few code optimizations here and there
