transplant: widen wlock scope of transplant for consitency while processing
Before this patch, "hg transplant" executes below before acquisition
of wlock.
- cmdutil.checkunfinished()
- repo.status() for dirty check
- repo.dirstate.parents()
It may cause unintentional result, if another command runs parallelly
(see also issue4368).
This patch makes "hg transplant" acquire wlock before processing
instead of acquiring wlock in each of 'transplanter.apply()' and
'transplanter.recover()'.
