[Subject:  vcs-svn: implement prop-delta handling.]

By testing against the Apache Software Foundation
repository, some simple rules for decoding prop
deltas were derived.

'Node-action: replace' implies the empty prop set
as the base for the delta.
Otherwise, if a copyfrom source is given that node
forms the basis for the delta.
Lastly, if the destination path exists in the active
revision it forms the basis.

These rules are used for text deltas, too, right?  Probably
worth mentioning the new (placeholder) fast_export_blob()
parameter in the commit message.
