Alasdair G Kergon 4db6bfe02b dm snapshot: split out exception store implementations 
Move the existing snapshot exception store implementations out into
separate files.  Later patches will place these behind a new
interface in preparation for alternative implementations.

Jonathan Brassow aea53d92f7 dm snapshot: separate out exception store interface 
Pull structures that bridge the gap between snapshot and
exception store out of dm-snap.h and put them in a new
.h file - dm-exception-store.h.  This file will define the
API for new exception stores.

Ultimately, dm-snap.h is unnecessary, since only dm-snap.c
should be using it.
