d36beb3f69 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. 
None of these symbols should be accessed directly, so declare them as
hidden.

645e75992d Fix GSM decoding: regular GSM and MSGSM do not use the same 
bitstream endianness, so they cannot reuse the same code
without a lot of function call overhead.
Thus use templating to compile two different binaries.
