MongoDB upgrade - Upgraded MongoDB and drivers to mongodb-c-driver 1.5.1, libbson 1.5.1 and MongoDB v3.4.0
- The upstream mongodb-c-driver has deprecated the old OP_QUERY syntax
with $-modifiers and old names like $orderby and $query, which will
be removed from the driver. The new interface is more in the mongodb
style, many former parameters (e.g. -limit, -skip, -project, -sort)
went to the new "-opts" argument.

mongo::collection::query /collection/ /filter/ ?-opts /opts/?
mongo::cursor::find /collection/ /filter/ ?-opts /opts/?

See the begin of nsf-mongo.test file for examples for queries
with the old and new interface. The high level interface
for nx::Object is unchanged.

- Support for new binary type "decimal128"
