and if anyone has suggestions for better names for some options now is the
right time as compatibility is slightly broken anyway

and a few specific questions
currently all AVOption constants are upper case so for example '-idct SIMPLE'
is that ok, or do people want lowercase for them?

the flag set/unset syntax looks like '-debug +PICT+MMCO-STARTCODE+8'
any comments about that? 
stuff like '-MV4' instead of '-flags +MV4' works also almost already
or should it be '+MV4'? later seems more logic but might be problematic
for some applications (ffmpeg.c is one as it strips and expects the '-' but 
it should be easy to fix)
