Now we use the Malamute broker instead of Majordomo

The hardcoded filename is not robust and should change in the
near future

The MDP protocol is now unmaintained and not suitable for deployment
as the error cases are not handled correctly. Moreover, the MDP
reference design is not following CZMQ 3.0.0 series.

Particularly, get rid of zctx and zthread in favor of
zsock and zactor classes.

WARNING! This commit will not work as we don't use zctx anymore,
but Majordomo still needs it!

This is the new name in czmq 3.0 series, as zcts class
is deprecated.

We don't have a compile-time constant for the size of
smio_mod_dispatch []. So, we append a end-of-array
object.

We still need to convert zthread and zcontext, which are
deprecated by now, to the new czmq 3.0.0 API.

This is more robust as #!/usr/bin/env searches the
PATH env variable for bash.

For now, we fetch the latest image on any branch.

This will fetch submodules of submodules, if any.

We were pointing to a non-existing tree, as we recently
changed the bpm-sw-cli to lnls-dig organization

We were checking for a wrong TAG. The correct one is MSG_EXP_ZMQ
and not MSG_THSAFE_ZMQ

If we have received an empty string for the bind AFE address,
we don't spawn a new dev_io.

This was the old name of our core application. Now,
"hal" targets/rules was replaced by "core" targets/rules

This was fixed in commit 599629c7, but due to a faulty merge
(b8d1f10e) this was broken again.

Now, poller2 and *_poll2 () functions were renamed
to poller and *_poll () as there is only one poll
mechanism now.

This was probably due to a faulty merge.
