dirstate: make dirstate.write() callers pass transaction object to it
Now, 'dirstate.write(tr)' delays writing in-memory changes out, if a
transaction is running.
This may cause treating this revision as "the first bad one" at
bisecting in some cases using external hook process inside transaction
scope, because some external hooks and editor process are still
invoked without HG_PENDING and pending changes aren't visible to them.
'dirstate.write()' callers below in localrepo.py explicitly use 'None'
as 'tr', because they can assume that no transaction is running:
- just before starting transaction
- at closing transaction, or
- at unlocking wlock
