Rostislav Pehlivanov 0fc3a51353 lpc: add ff_lpc_calc_ref_coefs_f() function ...

This commit adds a function to get the reflection coefficients on
floating point samples. It's functionally identical to
ff_lpc_calc_ref_coefs() except it works on float samples and will
return the global prediction gain. The Welch window implementation
which is more optimized works only on int32_t samples so a slower
generic expression was used.
