Fix two more leaking tmp dirs, by reworking TransformPreview lock handling.

* bzrlib/tests/test_transform.py:
(TestTransformMerge): Revert previous patch and cleanly call
preview.finalize now that we can.

* bzrlib/tests/test_merge.py:
(TestMerge.test_make_preview_transform): Catch TransformPreview
leak.

* bzrlib/builtins.py:
(cmd_merge._do_preview): Finalize the TransformPreview or the
limbodir will stay in /tmp.

* bzrlib/transform.py:
(TreeTransformBase.__init__): Create the _deletiondir since it's
reffered to by finalize.
(TreeTransformBase.finalize): Delete the dir only if _deletiondir
is set.
(TreeTransform.__init__): Use a temp var for deletiondir and set
the attribute after the base class __init__ has been called.
(TransformPreview.__init__): Read locks the tree since finalize
wants to unlock it (as suggested by Aaron).

Distributed VCS tools offer new ways of working together,

ways that better reflect the modern world we live in and

ways that enable higher quality outcomes.

The decentralized with shared mainline workflow

-----------------------------------------------

In this workflow, each developer has their own branch or branches, plus commit rights to the main branch. They do their work in their personal branch, then merge it into the mainline when it is ready.
