This hides some of the low-level parsing details from the
StreamingParser. These don't need to be known when parsing a complete
slice at once (which is we can usually do).
Also, remove `Json` from Parser names. The namespace `json` is sufficient.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'
