The LGPLv3 license is not suitable to our project
as it is not a library, for instance. GPLv3 is still
compatible with our libraries (LGPLv3 for libzmq)
and provides us with roughly the same benefits.

This is a first setp into modularizing the source code into
independent components. We would like to move as much as
possible functionality into independent libraries (src/libs).

We can iterate in this array by checking for a NULL field.

The include rw_param_client.h should not be in the
bpm_client_codes.h file as it is exported to the user
and does not have access to it.

As the rw_param_client.h definitions are only needed
internally, we just included it in the necessary .c files.

The new included header contatins information about the
message contents, particularly about frame sizes.

Now, we can simply reference the general SMIO file
that includes all other SMIO codes.

Also, removed unused code structure
