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.

Behdad Esfahbod 95df00aec1 Hide a few static methods
Looks like static methods that do not get inlined end up exported.
We have a lot more.  Need to protect all at some point.  Wish there
was an easier way, like the visibility flag we pass that automatically
hides all inline methods.

Was exposed by check-symbols.sh when compiling on OS X 10.14 with:
