This is more compatible and not more complicated.

The specification does not prevent an encoder to write the amplitude 0
as 0 amplitude_bits.

Our get_bits() implementation might not support a zero sized read
properly, thus the additional branch.

Rate and order must not be 0 even if the specification does not say that
explicitly.

Use the commonly used "if (!var)" instead of "if (var == 0)".

The value is used to calculate output LSP curve and a division by zero
and out of array accesses would occur.

Avoids an option name conflict with libavcodec, which is needed in order
to work properly with avconv.

Damaged frames can lead to a mismatch, which can cause a segfault
due to using an incorrect channel mapping.

While we do not use Automake in libav, this allows our config to be
used more globally without introducing unwanted breakage.

The init functions marked as av_cold have to be executed in any case,
so there is no gain from trying to mark paths leading to such functions
as unlikely.

This also allows libx264 to modify its i_qfactor value
when using the "-tune" setting. Previously it had a static
value of 1.25
