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.

/*
 * Unfortunately the code we got from ETSI makes heavy use of two global
 * Boolean flags named Carry and Overflow that function like equally named
 * processor state flags on many CPU architectures.  They are not part
 * of persistent codec session state for either the encoder or the decoder,
 * instead they are "short-term" globals much like UNIX errno.
 *
 * Given this unfortunate reality plus the natural desire to make our
 * AMR library thread-safe (a transcoding MGW handling a large volume of
 * simultaneous calls is exactly the kind of application that would benefit
 * from utilitizing all CPU cores), our current workaround is to use
 * thread-local storage.
