a005174b25 Remove unused code under G729_BITEXACT #ifdef. 
G729_BITEXACT is never set, so the code is all dead code.

33ae681f5c Expose QCELP's floating-point LSP-to-LPC function 
qcelp_lsp exported a single function, ff_acelp_lspd2lpc, which was not
specific to qcelp. It can be kept with its fixed-point version
ff_acelp_lsp2lpc in lpc.c.

4deaa94639 Add shift argument to MULL() macro 
This replaces use of FRAC_BITS in the MULL() definition with a third
argument specifying the shift amount.  All uses of this macro are
updated to pass FRAC_BITS as third argument.
