It's redundant -- -flags +psnr does the same thing.

It's only shadowing the AVOption with the same name.

Also remove redundant -pix_fmt list syntax, it's inconsistent and  only
makes the code more complicated. -pix_fmts should be enough for
everyone.

Merge video_qscale (set by -qscale) and audio_qscale (set by -aq) into
one 'qscale' field in the options context. Add a shortcut -q for -qscale
and make -aq an alias for -q:a.

Remove now redundant (and broken/undocumented) opt_programid.

Also document it and replace undocumented and inconsistent
'-sample_fmt list' syntax with -sample_fmts.

They are redundant, the same can be now accomplished with -metadata.

Add a new -tag option, make -[vas]tag an alias for -tag:[vas]

init_get_bits() takes a number of bits and not a number of bytes as
its size argument.

They will only ever be <=0 if the option is broken, in which case this
check is hiding a bug.

It's a hack which was created to allow for multiple options with
different defaults to refer to same field (e.g. 'b' vs 'ab'). There is
no need for it anymore.

Also change it to be more readable.
