index: split up nt_init() in two

I'd like to make nt_init() take a pointer to a nodetree to initialize,
but it currently also allocates the nodetree. This patch prepares for
that change by making nt_init() be about initializing an existing node
tree and by creating a new index_init_nt() that creates the nodetree.

  $ hg init foo
  $ cd foo
  $ echo foo > foo
  $ hg add foo

mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:

  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]
  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]

  $ cd ..
