Perform string content comparison in SmackableImp::getName

This may have worked by accident if the invoked methods returned the
same static string objects, but better replace this with a proper check.

Let database count unread messages

Instead of generating a list of unread messages, let the database count
them and return this number. Slightly more efficient.

Replace updateOrInsertRosterEntryToDB on status updates with updateRosterEntryInDB

There is no obvious reason that we need special DB updates to store a
new presence code. The DB must already contain the corresponding roster
entry, so just call updateRosterEntryInDB and drop the now unused
updateOrInsertRosterEntryToDB.

Enhance updateRosterEntryInDB to add new entries on demand

Call addRosterEntryToDB from updateRosterEntryInDB if the entry does not
exist yet. This allows to start using it from setRosterEntries, in
preparation of preserving the roster table across connections.

Preserve roster table across connections

Instead of dropping all entries from the roster table on reconnect,
update existing ones or add new entries based on the server DB, and drop
those entries that were removed from the server. This will allow to
maintain additional data in the roster entries.

Drop groups table

These days we only use the groups table to identify is some group was
added or removed. But this approach is not perfect either as it doesn't
allow us to find out if a group became virtually empty (no more online
members).

This commit just raises a change notification for the group URI along
with any content change. No relevant impact on the visualization of the
roster could be found so far. Instead, the code becomes much simpler.

Hide groups without available members

Reactivate the disabled code in RosterExpListAdapter.requery. It works
now as we report any content change also as group URI change.

Do not try to reconnect while network is disconnected

This avoids error messages and periodic reconnect attempts while we lack

allowing to reestablish the link.
