Unnecessary since 1f63665ca5, because
the value the option is set to coincides with the default value.

By using preinit, the AVDCT already exists directly after
allocating the filter, so that the filter's AVClass's child_next
becomes usable for setting options with the AV_OPT_SEARCH_CHILDREN
search flag. This means that it is no longer necessary to use
the init_dict callback for this filter.
Furthermore, the earlier code did not abide by the documentation
of the init_dict callback at all: Instead of only returning the
options that have not been recognized it always returned all options
on any av_opt_set() error and errored out in this case, even if it
is just an unrecognized option. This behaviour has been inherited by
avfilter_init_dict(), contradicting its documentation. This is also
fixed in this commit.

zimg's color range enum values are off-by-one compared to ours;
therefore the code just adds one when converting from theirs to ours.
Yet this is not how one should deal with enums; use a switch instead.

The problem was caused by if the width of the processed block
minus 1 is a multiple of the aligned number the instruction
jle .bscale_scalar would skip the Optimized Loop Step, which
will lead to an incorrect sampling when specifying steps more
than 1. Move the Optimized Loop Step after .bscale_scalar to
ensure the loop step is enabled.

This filter chain was supposed to convert from narrow range
to full range yuv444p, but didn't:
buffer=width=1280:height=720:pix_fmt=yuv444p:frame_rate=25/1:\
time_base=1/25:sar=1/1,zscale=min=709:rin=limited:pin=709:\
tin=709:t=linear,format=gbrpf32le,zscale=tin=linear:p=709:m=709:\
r=full:t=709,format=pix_fmts=yuv444p,buffersink
Using ff_set_common_formats_from_list() avoids using different functions
depending upon how many inputs the filter has.

This macro will allow to share options between AVClasses without
having to redefine the option name (as is currently done) and will
also allow to share the AVClasses itself (which is possible now
that AVClass.child_class_next is gone).
