msm8974-common: libril: Add Samsung changes

***** SIGNAL STRENGTH HACKS NOT PORTED YET *****

[javelinanddart]: Redo this code from 14.1 to include
  the proper RIL_Call fixes, no Samsung unsol/request
  handling as it was unnecessary, and a extensible way
  to remap RIL unsols if necessary for the device
