Presumably, the C type MsgType was meant to hold the protocol message type in 
the pre-version-3 era, but this was never fully developed even then, and the 
name is pretty confusing nowadays.  It has only one vestigial use for cancel 
requests that we can get rid of.  Since a cancel request is indicated by a 
special protocol version number, we can use the ProtocolVersion type, which 
MsgType was based on.  (If this is also found confusing, we could also use 
uint32 directly.)

LGTM. I searched over the source tree, MsgType had only a single usage before 
the patch, so it makes sense to remove it.

committed, thanks
