media-video/vlc: add dav1d-1.0.0 patch

It's unmerged (pending upstream) but
nobody's complained of runtime issues and the
patch itself wasn't disputed; just whether there's
another separate runtime bug which people
noticed during review of the patch.

Closes: https://bugs.gentoo.org/835787

+Subject: [PATCH 1/2] dav1d: fix compilation with (upcoming) dav1d 1.0
+
+(cherry picked from commit dbf45cea2a8abdfbef897b8a71f3eb782bb1b712) (edited)
+edited:
+- 3.0 has the 128 pixels padding elsewhere
+- 3.0 has an extra parameter for add_integer_with_range()
+- 3.0 was setting i_extra_picture_buffers further down in the code
+- 3.0 uses 16 threads max
