Adding C-band receiver supporto to centos_7_compatibility (#811)

* fix issue #806: Preliminary support for C band receiver at the SRT. IF2 conversion control, component configuration, data configuration, Station procedure, changelog, Receivers boss configuration are still missing.
I also recoded some parts of the system in order to get rid of the warnings  coming from new gcc compiler. Introduced a GCC
Compiler Directive workaround to by pass warning from ACS source code.

* fix issue #806: Recoding to overcome warnings during compilation ended. Drawbacks are not expected but a check is required
since some library header files have been touched. Added all missing receiver configurations (mnemonic is CCG).
Missing other subsystem configurations such us servo system or backend. Missing as well the part to control
the board for the 1st and 2nd conversion of the receiver.

* fix issue #806: a couple of fixes to guarantee nothing is broken by the changes made to get rid of deprecated code
