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.
