[media] docs-rst: fix cross-references for videodev2.h

There are several broken references there, due to the conversion to
C domain. Fix them using this shell script and manually adjust what's
broken:

	# funcs is a file with the broken functions/references
	for i in $(cat funcs|sort|uniq|perl -ne 'print "$1\n" if (m/(\S+)$/)'); do
		i=${i//-/_}
		echo $i
		j=${i//_/-}
		for k in $(git grep -l "_$j:" Documentation/); do
			sed s,\_$j\:,"c\:type\:\: $i", <$k >a && mv a $k
		done
		for k in $(git grep -l "$j" Documentation/media/*.exceptions); do
			sed s,$j,":c\:type\:\`$i\`", <$k >a && mv a $k
		done
		for k in $(git grep -l "$j" Documentation/); do
			sed "s,:ref:\`$i <$j>\`,:c:type:\`$i\`," <$k >a && mv a $k
			sed "s,:ref:\`$j\`,:c:type:\`$i\`," <$k >a && mv a $k
			sed -E "s,:ref:\`(.*)<$j>\`,:c:type:\`\1<$i>\`," <$k >a && mv a $k
		done
		for k in $(git grep -l "<$j>" include/media); do
			sed -E "s,:ref:\`(.*)<$j>\`,enum \&$i," <$k >a && mv a $k
		done
	done
