[NEW] MongoDB Database Driver


A new *CACHEDB_MONGODB* module has been added to OpenSIPS trunk, and it
will also be present in the future 1.9 release.

The module implements the Key-Value Interface [1] to allow the script
writer and also the module writer to connect and do Key-Value type
operations ( store,fetch,remove,counter_add,counter_sub ) on a MongoDB
The module supports both connection to a single MongoDB instance ( true
single instance or mongos ) or to a MongoDB Replica Set.

Also, the CacheDB interface was enhanced in order to support RAW queries
( [2] ). Due to the Key-Value nature of the CacheDB interface, the
developer could not take full advantage of the capabilities of the NoSQL
back-end. The raw queries should compensate that gap, allowing to run
raw queries in a back-end dependent language.

The CACHEDB_MONGODB module implements the newly added RAW query from the
interface, thus you can run whatever query that the MongoDB back-end
supports, taking full advatange of it. The query syntax is a JSON-based
one, very similar to the one that one would use to run commands in the
mongo CLI. The query results are also returned as JSON documents, that
one can further process in the OpenSIPS script by using the JSON module.
For the full description of the raw query capabilities, see the 'Raw
Query Syntax' section ( [3] ) in the module documentation.

Testing and feedback is very much welcome.
