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.

/*
 * gsmfr_preproc_good_frame_hm() is a wrapper around gsmfr_preproc_good_frame()
 * that adds homing of the Rx DTX handler preprocessor block.  This homing
 * version of good frame preproc is not used in the full decoder (the latter
 * implements its own homing logic as specified by 3GPP), but it will be used
 * when our Rx DTX handler preprocessor functions as a TFO transform.
