Changing type of integer fields in proto message

[Pavel Patrin]

Hello everyone.

I want to replace `int64` type to `uint64` type in proto file for field that contains timestamp with milliseconds.

The byte value length is 41 bit, and it is safe to do that in C.

But what about protobuf with it's dynamic-size integers? Can I do such replacement?
