Vladimir Serbinenko c5373134d2 COMMON: Uplift rnc decoder from toon to common
Toon has a RNC implementation with 2 differences from the one taken from SKY:

1. Protection against overread. Add it to common version and adjust callers
   in sky.
2. Lack of key parameter for obfuscation. We ignore it anyway and don't
   support obfuscation, so delete it in common version as well
