dirstate: track updated files to improve write time
Previously, dirstate.write() would iterate over the entire dirstate to find any
entries that needed to be marked 'lookup' (i.e. if they have the same timestamp
as now). This was O(working copy) and slow in large repos. It was most visible
when rebasing or histediting multiple commits, since it gets executed once per
commit, even if the entire rebase/histedit is wrapped in a transaction.
The fix is to track which files have been editted, and only check those to see
if they need to be marked as 'lookup'. This saves 25% on histedit times in very
large repositories.
I tested this by adding temporary debug logic to verify that the old files
processed in the loop matched the new files processed in the loop and running
the test suite.

hook: give exthooks tags for blocking time
The ui.system autogenerated tag isn't really useful - as they're named, let's
use the name the user gave us.
