dirstate.status: assign members one by one instead of unpacking the tuple
With this patch, hg status and hg diff regain their previous speed.
The following tests are run against a working copy with over 270,000 files.
Here, 'before' means without this or the previous patch applied.
Note that in this case `hg perfstatus` isn't representative since it doesn't
take dirstate parsing time into account.
