They were derived from incorrect values cr=0.2125 (should be cr=0.2126)
and cb=0.0721 (should be cb=0.0722).

880e2aa236 Remove all Blackfin architecture optimizations
Blackfin is a painful platform to work with, no test machines are available
and the range of multimedia applications is dubious. Thus it only represents
a maintenance burden.

b64a72e1b2 yuv2rgb: handle line widths that are not a multiple of 4.
This introduces support for width%4==2 in addition to width%4==0. For
odd widths, some more checks are needed, since the current code always
handles two luma items in a row, thus there is a possibility of an
overread by one.
