Some debugging improvements.

- Fix dumping of package manager intent filters so the option
  to print the filter detail works again.
- Extend dump resolvers to allow you to specify the specific
  types of resolvers you'd like to dump.
- Add new package manager commands for querying activities,
  services, receivers.
- Move the code for parsing a command line into an intent to
  the framework, so it can be used by the new package manager
  commands and later elsewhere.
