eol: the hook no longer requires the extension to be loaded

Reading rules in the hook means we no longer need ui to be filled and do not
need reposetup() to be run anymore.

Test issue 902

  $ hg commit -m "test2"
  $ hg branch test
  marked working directory as branch test
  $ hg rollback
  repository tip rolled back to revision -1 (undo commit)
  working directory now based on revision -1
  $ hg branch
  default

Test issue 1635 (commit message saved)
.hg/last-message.txt:

  $ cat .hg/last-message.txt ; echo
  test2

Test rollback of hg before issue 902 was fixed

  $ hg commit -m "test3"
  $ hg branch test
  marked working directory as branch test
  $ rm .hg/undo.branch
  $ hg rollback
  repository tip rolled back to revision -1 (undo commit)
  Named branch could not be reset, current branch still is: test
  working directory now based on revision -1
  $ hg branch
  test

rollback by pretxncommit saves commit message (issue 1635)

  $ echo a >> a
  $ hg --config hooks.pretxncommit=false commit -m"precious commit message"
  transaction abort!
  rollback completed
  abort: pretxncommit hook exited with status * (glob)
  [255]

.hg/last-message.txt:

  $ cat .hg/last-message.txt ; echo
  precious commit message

same thing, but run $EDITOR

  $ cat > editor << '__EOF__'
  > #!/bin/sh
  > echo "another precious commit message" > "$1"
  > __EOF__
  $ chmod +x editor
  $ HGEDITOR="'`pwd`'"/editor hg --config hooks.pretxncommit=false commit 2>&1
  transaction abort!
  rollback completed
  note: commit message saved in .hg/last-message.txt
  abort: pretxncommit hook exited with status * (glob)
  [255]
  $ cat .hg/last-message.txt
  another precious commit message
