This involved fixing a few important bugs in the
Ruby implementation -- mostly cases of mixing
upb field types and descriptor types (upb field
types do not distinguish between int/sint/fixed/sfixed
like descriptor types do).
Also added protobuf-specific exceptions so parse
errors can be caught specifically.

This allows us to enable conformance tests even when we know
that some tests are failing and need to be fixed.
