Some hints:
- Try to understand the filelog/manifest/changelog hierarchy first
  and ignore everything you might know about contexts.
- All these various revlogs are append-only, so you can't remove
  things. Removing files from the next changelog revision is done by
  appending a new manifest revision which no longer lists the file.
- Contexts just present a view on these revlogs or on the working
  dir in a unified way. Don't look at them to understand the design,
  only look at them to use them as an API :)
