parser: Halt parser on DTD errors

If we try to continue parsing after an error in the internal or external
subset, entity expansion accounting gets more complicated. Simply halt

Found with libFuzzer.

relying on in->consumed, which could overflow, change some DTD parser
functions to make guaranteed progress on certain byte sequences.
