Uninitialized coefficients were being used to generate exponents, some
of which actually ended up in the final stream. Even though, they were
just extra exponents that are not used by any decoder, it is still
better to have consistent output for testing. This also fixes valgrind
errors.
Having a separate section for audio encoders simplifies navigation
and is slightly more consistent with the rest of the manual.

The attached patch fixes the crash which happens when user passes lowres value lower than 0 to FFplay.

This actually matches what av_get_double did earlier, the
0.0/0.0 division was intentional, for producing NAN.
Still keeping the check for the return value from
av_get_number, for clarity.

Some received packets can have size 0. The return value from
av_malloc(0) may be NULL, which is ok if the size was 0. On
OS X, however, the returned pointer is non-null but leads to
crashes when trying to free it.

Grow the file and stream list in opt_input_file() instead of creating it
all at once in transcode(). This is simpler and will be useful for
following commits.
