ofproto-dpif: Expose datapath capability to ovsdb.
The patch adds support for fetching the datapath's capabilities
from the result of 'check_support()', and write the supported capability
to a new database column, called 'capabilities' under Datapath table.
To see how it works, run:
# ovs-vsctl -- add-br br0 -- set Bridge br0 datapath_type=netdev
# ovs-vsctl -- --id=@m create Datapath datapath_version=0 \
'ct_zones={}' 'capabilities={}' \
-- set Open_vSwitch . datapaths:"netdev"=@m
# ovs-vsctl list-dp-cap netdev
