localrepo: execute appropriate actions for dirstate at releasing transaction
Before this patch, in-memory dirstate changes are still kept over a
transaction scope boundary regardless of the result of it.
For "all or nothing" policy of the transaction, in-memory dirstate
changes should be:
- written out at successful closing a transaction, because
subsequent 'dirstate.invalidate()' can lose them
- discarded at failure of a transaction, because outer
'wlock.release()' or so may write them out
To discard all changes in a transaction completely, this patch also
restores '.hg/dirstate' by '.hg/journal.dirstate' at failure, because
'transaction' itself does nothing for files related to '.hg/journal.*'
in such case (therefore, renaming in this patch is safe enough).
This is a part of preparations for "transactional dirstate". See also
the wiki page below for detail about it.

This patch also removes redundant 'dirstate.invalidate()' just before
aborting a transaction for shelve/unshelve.
