Add the 'inc-proc-eng' framework to northd. This does *not*
add any incremental processing at this stage but provides the
framework to do so. Even in this base configuration, we see an
advantage as northd no longer processes the databases if it has
been woken only to handle, for example, a unixctl command. This
can be seen below
$ ovn-appctl -t ovn-northd stopwatch/reset
$ for i in {1..10}; do ovn-appctl -t ovn-northd stopwatch/show >/dev/null; done
$ ovn-appctl -t ovn-northd stopwatch/show ovnnb_db_run
Statistics for 'ovnnb_db_run'
Total samples: 0
Maximum: 0 msec
Minimum: 0 msec
95th percentile: 0.000000 msec
Short term average: 0.000000 msec
Long term average: 0.000000 msec
Hopefully this starting point will allow others to discuss or contribute
changes to incrementally process some aspects of northd. We an also
decide if it is worth progressing with this in general.
Thanks,
v2: Rebase
v3: Fix compile error in 2/7 picked up by 0-day robot
v4: Rework based on Han's comments and rebase

inc-proc-eng: Allow definition of engine_node with global scope
northd: Introduce incremental processing for northd
northd: Add n_nat_entries field to 'struct ovn_datapath'
northd: Introduce struct northd_data
northd: Add lflow node
northd: Do not calculate database sequence numbers incrementally
