Damien Neil e6f060fdac proto: add Equal
Add support for basic equality comparison of messages.

Messages are equal if they have the same type and marshal to the
same bytes with deterministic serialization, with some exceptions:

 - Messages with different registered extensions are unequal.
 - NaN is not equal to itself.

Unlike the v1 Equal, a nil message is equal to an empty message of
the same type.
