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.

This will allow to reuse the code in the SIPR decoder.
