2-pass VBV support and improved VBV handling
Dramatically improves 1-pass VBV ratecontrol (especially CBR) and provides support for VBV in 2-pass mode. This consists of a series of functions that attempts to find overflows and underflows in the VBV from the first-pass statsfile and fix them before encoding. 1-pass VBV code partially by Fiona Glaser.
