Currently, the amount of padding inserted at the beginning by some audio
encoders, is exported through AVCodecContext.delay. However
- the term 'delay' is heavily overloaded and can have multiple different
  meanings even in the case of audio encoding.
- this field has entirely different meanings, depending on whether the
  codec context is used for encoding or decoding (and has yet another
  different meaning for video), preventing generic handling of the codec
  context.

Therefore, add a new field -- AVCodecContext.initial_padding. It could
conceivably be used for decoding as well at a later point.

Also break some long lines, remove codec function placeholder comments
and add spaces in sample/pixel format lists.

Specifically, ff_mpeg4audio_sample_rates, ff_mpeg4audio_get_config and
ff_copy_pce_data

It's more readable and less prone to breakage.

Use the correct error codes and format identifier.

Include VisualOn to clarify the codec name, but remove the
actual library name from the user-friendly description.
Also mention Android, to clarify which VisualOn implementation
this refers to, since they do sell other variants of the same
code, too.
