If AVCodecParameters.codec_tag is 'hvc1' use it instead of 'hev1' for

This (and the rest of your patches except 2/4 as you mentioned yourself)
look good and are a sensible addition.
However what I'm left wondering is as a next step, after making this
possible at all, is what should be the default? If the default isn't
compatible with apple tools, I'm pretty sure it'll be a very frequently
asked question at least. I guess it's doable via the -tag flag on the
command line or something like that, but it feels a little clunky.
But don't let that hold up your patches, since they generally are a step
in the right direction.
