53626d16e3 Support for roster versioning (EJAB-964)
Introduces two options for mod_roster and mod_roster_odbc:
- {versioning, true | false}   Enable or disable roster versioning on ejabberd.
- {store_current_id, true | false}   If true, the current roster version is stored on DB (internal or odbc). Otherwise it is calculated on the fly each time.

Performance:
Setting store_current_id to true should help in reducing the load for both ejabberd and the DB.

Details: 
If store_current_id is false,  the roster version is a hash of the entire roster. If store_current_id is true, the roster version is a hash, but of the current time
(this has to do with transactional semantics; we need to perform both the roster update and the version update on the same transaction, but we don't   
have the entire roster when we are changing a single item on DB. Loading it there requires significant changes to be introduced, so I opted for this simpler approach).

In either case, there is no difference for the clients, the roster version ID is opaque.

IMPORTANT:
mod_shared_roster is not compatible with the option 'store_current_id'.  Shared roster and roster versioning can be both enabled, but store_current_id MUST be set to false.
