For whatever reason most of the files had their permission
changed from 644 to 755, which is not wanted.

* the RAN API RRC part now takes rnti and does not look it up in the MAC every
  time again
* the function flexran_get_aperiodic_cqi_rep_mode() has been changed to return
  a proper protobuf variable, not OAI typedef

protobuf-c does not compile anymore.

Let's handle this a bit better.

We now install protobuf and protobuf-c only for the
flexran agent. That is, if you want to use the flexran
agent, you need to install protobuf/protobuf-c and
you do it this way:

  ./build_oai -I -a

(you add -a)

Other targets don't need protobuf nor protobuf-c, so
it's not installed by the -I command of build_oai,
unless you pass -a with -I.

Also, we now use protobuf 3.3.0, not 2.6.1. The code
has been adapted, a quick test seems to indicate that
the system works, but it has not been intensively tested.

Integrated progRAN config messages to OAI agent and created stubs for handler and destructor functions
