Added fake mrproper, just for compatibility with
other Makefiles

Now, we configure our dev_mngr and dev_io instances
through a simple configuration file.

This error is used when some error related to the
configuration file was detected, such as: missing
property, missing file, etc.

This configuration file, in the format zeroMQ ZPL language,
will be used for configuring the dev_mngr and dev_io
instances.

Add simple two-step stringify macro

This fixes #67 github issue

On spawning of our regular DEVIO, we spawn two additional
RFFE DEVIOs for controlling the RFFE boards.

As we merged the dev_io main program back into a single
code, we need a way to pass additional arguments to it.
So, we declare an dev_io_type parameter, meaning what SMIOs are
spawned, and a smio_inst_id parameter, used for DEVIOs with a
single SMIO, but multiple instances of it.

Only the most necessary functions are here. Missing
some functionality.

This makes it easier to maintain, reduces the amount of
code duplication and allow to make more generic code to
instantiate different types of DEVIOs

Now, we can easily interface with exported functions with any type
of parameter

RFFE is not actually a chip in a physical way, but a
whole device with some communication protocol. So, in this way,
we can treat it just like a IC and use our same architecture.

Some messages have the possibility to return an empty data frame,
such as the read_block function when reading 0 bytes.

This fixes #64 github issue

Now, we can reuse these functions for similar string to enum
conversions

Added new LLIO operations for ethernet devices

Now, an exported function can have an argument that
has a variable size, up to the maximum specified in
the function description. Particularly useful for
returning data from "read" functions

Cleaned the constructor and destructor methods, as well as usage
of the new smpr_set_handler () and smpr_unset_handler () functions
