Features:
- streaming reading/writing
- filtering
- reassembly of records
Reusing the ReadRecord infrastructure in situations where the code that wants
to do so is not tightly integrated into xlog.c is rather hard and would require
changes to rather integral parts of the recovery code which doesn't seem to be
a good idea.
Missing:
- "compressing" the stream when removing uninteresting records
- writing out correct CRCs
- separating reader/writer
