Garret Rieger 8ef4257dc8 [sanitize] change max ops to track number of bytes processed.
Counting bytes as the operations is likely to be a better proxy for how
much work processing the table will cost vs. the current approach of
counting the number of sub-objects.

This should allow checks for max features, max scripts, etc. to be removed.

I tested this change against the full collection of fonts at https://github.com/google/fonts
and a max ops factor of 3 was sufficient to successfully sanitize all of them.

Behdad Esfahbod c14efb8e68 Fix previous commit
Priority should be given to specific over dispatch.  Broke sanitize before.
This fixes it, by moving prioritization to the context implementation, since
the correct priority cannot be done in the dispatch implementation.  Done
for subset and sanitize only, which need it.
