libgsmhr1/dec_func.c: rm unused static functions In the original code, sp_dec.c held two kinds of functions: those needed only as part of the decoder, and those used by both decoder and encoder engines. In this library, we have moved the latter class of functions to dec_func.c module. Almost all static functions from the original sp_dec.c, with the exception of aToRc(), are needed only on sp_dec.c side of the new divide - remove them from dec_func.c, where they became dead code.

*  Function    : d_gain_pitch
*  Purpose     : Decodes the pitch gain using the received index.
*  Description : In case of no frame erasure, the gain is obtained 
*                from the quantization table at the given index; 
*                otherwise, a downscaled past gain is used.
*  Returns     : Quantized pitch gain
