g723_1: clip argument for 15-bit version of normalize_bits()
...
It expects maximum value to be 32767 but calculations in scale_vector()
which uses this function can give it ABS(-32768) which leads to wrong
result and thus clipping is needed.

g723_1: use all LPC vectors in formant postfilter
...
Due to some mistake LPC vector for the first subframe was used for all
subframes instead of their own LPC vectors.

g723_1: increase excitation storage by 4
...
Fixed codebook mode in 5300 rate may write up to SUBFRAME_LEN + 4 and
that is considered normal by the reference decoder. Without that additional
padding it might overwrite first elements of LPC history.

g723_1: save/restore excitation with offset to store LPC history
...
The same buffer with saved data is used later in LPC reconstruction, so
it should have some head space for LPC history.
