[coyotos-dev] Simplified tree fetch, update

[Jonathan S. Shapiro]

If you are trying to fetch the coyotos tree via mercurial, I just
changed the top-level makefile in a way that should help. You should now
be able to

  hg clone http://dev.eros-os.com/hg/coyotos
  cd coyotos/src
  make get_tree

This will query for each available subtree and let you obtain it.

Also, the make update and make status targets have been revised to use
mercurial.

The make sync and make destructive_sync targets are gone, since you can
now update directly from the repository.
