Before this commit vtep-ctl hung forever if it didn't manage to reach
the database.
This caused the testcase "ovn -- 3 HVs, 1 VIFs/HV, 1 GW, 1 LS" to hang
occasionally, because ovsdb-server could be killed before ovs-vtep
called vtep-ctl.
This mimics the behaviour of ovs-vsctl, ovn-nbctl and ovn-sbctl.

Two new tables are added to the VTEP schema, for ACL entries and
ACLs (which are groups of entries). The physical port table is modified
to allow ACLs to be associated with ports, and the logical router table
is modified to allow ACLs to be attached to logical router ports.

'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.

IDL-generated files don't need to be distributed, and distributing them
puts them in the source directory rather than the build directory, which
causes "make distcheck" to fail if any of them need to be remade. To
prevent this, this commit this removes them from ..._SOURCES, moving them
into nodist_..._SOURCES.
IDL-generated files all need to be cleaned, so this commit adds all of
them to CLEANFILES wholesale via a single CLEANFILES += $(OVSIDL_BUILT)
line in ovsdb/automake.mk, removing the individual additions from various
makefiles.
With this commit, "make distcheck" passes for me.

The coding style guidelines include the following:
- Pick a unique name prefix (ending with an underscore) for each
module, and apply that prefix to all of that module's externally
visible names. Names of macro parameters, struct and union members,
and parameters in function prototypes are not considered externally
visible for this purpose.
This patch adds the new prefix to the externally visible names. This
makes it a bit more obvious what code is coming from common command
line handling code.

In OVS, we currently use the term 'facility' to mean the place
where we log (syslog, console or file). In Linux's syslog() and
rfc5424, the term 'facility' is used to specify what type of program
is logging the message (e.g: LOG_DAEMON). This causes confusion
while reading vlog's code. This commit changes the term 'facility'
to 'destination'.

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 VTEP emulator creates one OVS bridge for every logical switch and then
programs flow in it based on learned local macs and controller programmed
remote macs.
Multiple logical switches can have multiple OVS tunnels to the
same remote machine (with different tunnel ids). But VTEP schema expects
a single BFD session between two physical locators. Therefore
create a separate bridge ('bfd_bridge') and create a single OVS tunnel
between two physical locators (using reference counter).
The creation of BFD tunnels by the VTEP emulator is mostly for reporting
purposes. That is, it can be used by the controller to figure out that
a remote port is down. The emulator itself does not base any of its
forwarding decisions based on the state of a bfd tunnel.

string.split() function splits a quoted string if there is a whitespace
inside the quote.
ex: The following code snippet will output ['printing', '"No', 'Diagnostic"']
args = 'printing "No Diagnostic"'
print args.split()
The above is a problem if we run the following command through vtep_ctl().
vtep-ctl set tunnel $uuid bfd_status:diagnostic="No Diagnostic"
The workaround is to use the split() function from shlex module.

'ps_name' and then passed around. An upcoming commit requires

To prevent warnings such as "Not all control paths return a value",
we should define NO_RETURN for MSVC.
Currently for gcc, we add NO_RETURN at the end of function declaration.
But for MSVC, "__declspec(noreturn)" is needed at the beginning of function
declaration. So this commit moves NO_RETURN to the beginning of the function
declaration as it works with gcc and clang too.
