Clean up qimage.cpp by moving all the conversions methods out

Browse Source 
A large part of qimage.cpp is the implementation of the various
conversions methods from one format to another. These methods could all
be moved to a separate file to make qimage.cpp smaller, and possible
later enable more aggressive optimization on the conversions.
