odp-util: add verbose mode for displaying dp flow.

Browse Source 
When verbose mode tuned on, all dp flow fields described by the netlink
attributes are displayed, including fully wildcarded attributes.
Otherwise, the fully wildcarded attributes are omitted for brevity.

Added -m option to "ovs-dpctl dump-flows" to enable verbose mode. It is
off by default.

- ovs-dpctl:
* New debugging commands "add-flow", "mod-flow", "del-flow".
* "dump-flows" now has a -m option to increase output verbosity.
- In dpif-based bridges, cache action translations, which can improve
flow set up performance by 80% with a complicated flow table.
- New syslog format, prefixed with "ovs|", to be easier to filter.
