Fix up the broken bits in findoutgoing

Move the empty changeset detection out of findincoming to pull This lets us reuse findincoming for findoutgoing

Protocol switch from using generators to stream-like objects. This allows the the pull side to precisely control how much data is read so that another encapsulation layer is not needed. An http client gets a response with a finite size. Because ssh clients need to keep the stream open, we must not read more data than is sent in a response. But due to the streaming nature of the changegroup scheme, only the piece that's parsing the data knows how far it's allowed to read. This means the generator scheme isn't fine-grained enough. Instead we need file-like objects with a read(x) method. This switches everything for push/pull over to using file-like objects rather than generators.

Add a repo method to report repo device This is used to establish whether repos are on the same device for hard linking. Remote repos all return -1.
