When ovs-sandbox is run with ovn enabled, create the vtep database and
run ovn-controller-vtep. This lets you do some basic testing with
ovn-controller-vtep. For example:
$ make sandbox SANDBOXFLAGS="--ovn"
$ vtep-ctl add-ps ps0
After those commands, you can see that ovn-controller-vtep added a
Chassis row to OVN_Southbound for the physical switch.

It came up in a recent discussion that the use of 'nbd' could cause
confusion since nbd is used for "Network Block Device", which may be
used in many of the same environments that OVN would be used in.
To avoid the possible issue, just rename ovn-nbd to ovn-northd.
While we're at it, create a subdirectory under ovn/ to hold all files
related to ovn-northd. For now it's just a single C file, but we
may add more source files in the future.

When running ovsdb-server under gdb, there is a race that ovs-vsctl
command can be called before ovsdb-server is fully launched. This will
cause ovs-vsctl to fail. This patch fixes this by delay issuing
the ovs-vsctl command until ovsdb-server is fully launched.

The current gdb support launches gdb but doesn't start the daemon.
If you start ovsdb-server with gdb, ovs-sandbox produces an error as
it tries to run ovs-vsctl before ovsdb-server is running. Telling gdb
to start the daemon immediately avoids this error.
There are cases where it's useful to go straight to the gdb prompt,
too. For example, someone may want to set a breakpoint. In that
case, it's easy enough to just kill it, set a breakpoint, and execute
'run' again.
In passing, fix indentation to use spaces instead of tabs.

Otherwise ovs-vswitchd can't immediately start working (until some other
call to ovs-vsctl initializes the database). This is most obvious if one
runs "ovs-vsctl list Open_vSwitch ." as the first command, because the
output will not show the changes that ovs-vswitchd will make to the
database at startup (in particular initializing datapath_types and
iface_types), which is confusing.

This patch adds initial support for OVN to ovs-sandbox. If you pass
"-o/--ovn" to ovs-sandbox, it will create a db from the ovn and ovn-nb
schemas and tell ovsdb-server to use them. It also adds ovn/ to $PATH
so that as ovn executables are added, they will be available in the
sandbox.

When debugging multiple programs under GDB, it will be easier to

It is some times useful to leverage the sandbox facility to experiment
and explore the internals of ovs-vswitchd. Since GDB requires console
access for user inputs, this patch launch an xterm for GDB, The main
terminal continue to run the sub-shell as before. Exiting the sub-shell
will also kill the ovs-vswitchd under GDB (but not GDB itself currently)

This utility isn't going to be as portable as most of the Open vSwitch
utilities, unfortunately. I'm happy to take improvements to make it
able to work with, e.g., the "man" program from BSD. (I haven't tested
with that program, but I suspect that it is somewhat different from the
GNU version.)
The output of this program can already be viewed at:
