Re: [libvirt] [PATCH v6 1/8] snapshot: Split domain forward typedefs into new file

Right now, snapshot_conf.h is rather large - it deals with three separate types: virDomainSnapshotDef (the snapshot definition as it maps to XML), virDomainSnapshotObj (an object containing a def and the relationship to other snapshots), and virDomainSnapshotObjList (a list of snapshot objects), where two of the three types are currently public rather than opaque. What's more, the types are circular: a snapshot def includes a virDomainPtr, which contains a snapshot list, which includes a snapshot object, which includes a snapshot def. In order to split the three objects into separate files, while still allowing each header to use sane typedefs to incomplete pointers, the obvious solution is to lift the typedefs into yet another header, with no other dependencies. Start the split by factoring out all struct typedefs from domain_conf.h (enum typedefs don't get used in function signatures, and function typedefs tend not to suffer from circular referencing, so those stay put). The only other excpetion is

virDomainStateReason, which is only ever used directly rather than via a pointer. This patch is just straight code motion (all typedefs are listed in the same order before and after the patch).
