Add more fields to RPC info replies

This patch adds the following fields to info and multiinfo replies:

* Depends
* MakeDepends
* CheckDepends
* OptDepends
* Conflicts
* Provides
* Replaces
* Groups
* License

Each of these fields is an array.

Note that since collecting all these fields is CPU-intensive, they are
not included in replies to search queries.
