Joshua Haberman	75488a0742	Created a new upb_WireReader interface for parsing wire data directly. The overall motivation for this interface is to consolidate many places in upb that are parsing wire format data directly. This interface is not yet complete, but this is a good start. We have enough to port the wire format parsing in accessors.c to this interface. We can follow up by porting more places that do wire format parsing. PiperOrigin-RevId: 498109788	2 years ago
Joshua Haberman	a48af3f824	Moved aliasing logic for string field parsing into EpsCopyInputStream. Moving the logic down to EpsCopyInputStream makes it easier to test and reuse this functionality. We also implement aliasing for the final bytes of the patch buffer, which has never been supported before. We used to always force a copy for any data parsed out of the patch buffer at the end of the stream. Much of this logic is ported directly from the C++ EpsCopyInputStream class.

Joshua Haberman	68d1d91475	Separated out buffering code into upb_EpsCopyInputStream. This mirrors the structure of C++ protobuf, which has an EpsCopyInputStream class. This will lay the foundation for making EpsCopyInputStream capable of true streaming, by reading its input from a ZeroCopyInputStream. It also lets us test EpsCopyInputStream separately from the decoder: see the new unit test that fuzzes upb_EpsCopyInputStream. After this CL is submitted, the two decoders (the normal decoder and the fast decoder) should no longer be accessing the members of upb_EpsCopyInputStream. PiperOrigin-RevId: 494400285	2 years ago

Separated out buffering code into upb_EpsCopyInputStream.

This mirrors the structure of C++ protobuf, which has an EpsCopyInputStream class.

This will lay the foundation for making EpsCopyInputStream capable of true streaming, by reading its input from a ZeroCopyInputStream.  It also lets us test EpsCopyInputStream separately from the decoder: see the new unit test that fuzzes upb_EpsCopyInputStream.

After this CL is submitted, the two decoders (the normal decoder and the fast decoder) should no longer be accessing the members of upb_EpsCopyInputStream.
