* - unknown fields can be inserted in random places
* - fuzzing of valid input
* - resource limits (max stack depth, max string len)
* - testing of groups
* - more throrough testing of sequences
* - test skipping of submessages
* - test suspending the decoder
* - buffers that are close enough to the end of the address space that
* pointers overflow (this might be difficult).
* - a few "kitchen sink" examples (one proto that uses all types, lots
