Synopsis:
Added "PreferredAudioPayload" option to dtdriver and aac-fileformat

Overview:
1) Introduced "PreferredAudioPayload" and "PreferredVideoPayload"
options into FFDriver.  These tell fileformat plugins to output their
streams in specified mime-type if possible (not obligatory).  Both
options are copied into fileformat's request header if specified.

2) Refactored AAC fileformat plugin to process "PreferredAudioPayload"
option.  Currently, it supports payload reformatting into
"audio/x-pn-realaudio".  This design is cleaner than depending on
"Server"=1 FFDriver option which should have the same effect.
