colorspace converter tests (memory corruption tests at different width/src/dst)

Browse Source 
quite impressive results only 1 of the 13 rgb->rgb converters fails for the c versions
... sadly only 1 of the mmx converters passes though :( ... i feared allready  that last mplayerxp merge reversed the bugfixes :((((
