Currently, command to add one item into a large set generates the
transaction with the full new content of that set plus 'wait'
operation for the full old content of that set. So, if we're adding
one new load-balancer into a load-balancer group in OVN using
ovn-nbctl, transaction will include all the existing load-balancers
from that groups twice.
IDL supports partial updates for sets and maps. The problem with that
is changes are not visible to the IDL user until the transaction
is committed. That will cause problems for chained ctl commands.
However, we still can optimize the very last command in the list.
It makes sense to do, since it's a common case for manual invocations.
Updating the 'add' command as well as 'set' for a case where we're
actually adding one new element to the map.
One downside is that we can't check the set size without examining
it and checking for duplicates, so allowing the transaction to be
sent and constraints to be checked on the server side in that case.
Not touching 'remove' operation for now, since removals may have
different type, e.g. if elements from the map are removed by the key.
The function will likely need to be fully re-written to accommodate
all the corner cases.

These utilities logged the command very early, before parsing the options
or the command. This meant that logging options (like --log-file or

The ovn-nbctl, ovn-sbctl, and ovs-vsctl manpages are inconsistent in
their "Database Commands" section when it comes to referring to what
database tables exist. This commit amends this by making each *ctl
manpage reference the corresponding database manpage instead.
To aid in having a more handy list, the --help text of ovn-nbctl,
ovn-sbctl, and ovs-vsctl have been modified to list the available
tables. This is also referenced in the manpages for those applications.

When one adds a new table to a database schema, it's easy to forget to
add the table to the list of tables in the *ctl.c program. When this
happens, the database commands for that program don't work on that table
at all, even for commands like "list" and "create" that don't need any
special help. This patch fixes that problem, by making sure that
db-ctl-base always has the complete list of tables.
Previously, each ctl_table_class pointed directly to the corresponding
ovsdb_idl_table_class. With this patch, there are instead two parallel
arrays, one of ovsdb_idl_table_classes and the other of ctl_table_classes.
This change accounts for the bulk of the change to the db-ctl-base code.

To easily allow both in- and out-of-tree building of the Python
wrapper for the OVS JSON parser (e.g. w/ pip), move json.h to
include/openvswitch. This also requires moving lib/{hmap,shash}.h.
Both hmap.h and shash.h were #include-ing "util.h" even though the
headers themselves did not use anything from there, but rather from
include/openvswitch/util.h. Fixing that required including util.h
in several C files mostly due to OVS_NOT_REACHED and things like
xmalloc.

'cmd_show_table'.
Sometimes, it is desirable to print the table with weak reference to
the table specified in 'struct cmd_show_table'. For example the
Port_Binding table rows in OVN_Southbound database that refer to the
same Chassis table row can be printed under the same chassis entry
in 'ovn-sbctl show' output.
To achieve it, this commit adds a new struct in 'struct cmd_show_table'
that allows users to print a table with weak reference to 'table'
specified in 'struct cmd_show_table'. The 'ovn-sbctl' which now prints
the Port_Binding entries with Chassis table, is the first user of this
new feature.
