Hi,

I am working to resolve https://www.nsnam.org/bugzilla/﷒0﷓ and I noticed that there are following unused functions in lte-ue-rrc.h/cc and lte-ue-simple-ue-component-carrier-manager.h/cc, respectively.

* DoComponentCarrierEnabling
* DoNotifyConnectionReconfigurationMsg

It seems these functions are the residue of an incomplete effort to remove/disable component carriers at runtime. Since this functionality is not implemented yet, I would suggest removing these functions from lte-ue-rrc.h/cc and simple-ue-component-carrier-manager.h/cc classes. And, keep their declaration in SAPs for any future reuse/extension.  

Following this change, the variable m_noOfComponentCarriersEnabled would be of no use, and can also be removed. We should use m_noOfComponentCarriers in place this variable in simple-ue-component-carrier-manager.cc. 

I am putting Alexander Krotov in Cc to get his feedback since he worked with CA during google summer of code.

Kind regards,
Zoraze
