7d485f165f Support for getting (i)MDCT output multiplied by a constant scaling factor. 
Scaling (i)MDCT output has no runtime overhead and can be used to improve
performance of audio codecs. All the changes are only needed in
'ff_mdct_init' function and slow down initialization a bit.

bad5537e2c Use full internal pathname in doxygen @file directives. 
Otherwise doxygen complains about ambiguous filenames when files exist

91ba93e68b vorbis_enc : set coded_frame->pts value to running sample count. 
This is a temporary fix for issue 502 and will not be required when
we start using AVFrame for audio codecs.
