status: use filesystem time boundary to invalidate racy mtime
We record the filesystem time at the start of the status walk and use that as a
boundary to detect files that might be modified during (or right after) the
status run without the mtime allowing that edition to be detected. We
currently do this at a second precision. In a later patch, we will use
nanosecond precision when available.
To cope with "broken" time on the file system where file could be in the
future, we also keep mtime for file over one day in the future. See inline
comment for details.
Large file tests get a bit more confused as we reduce the odds for race
condition.
As a "side effect", the win32text extension is happy again.

Our full contribution guidelines are in our wiki, please see: https://www.mercurial-scm.org/wiki/ContributingChanges If you just want a checklist to follow, you can go straight to https://www.mercurial-scm.org/wiki/ContributingChanges#Submission_checklist If you can't run the entire testsuite for some reason (it can be difficult on Windows), please at least run `contrib/check-code.py` on any files you've modified and run `python contrib/check-commit` on any commits you've made (for example, `python contrib/check-commit 273ce12ad8f1` will report some style violations on a very old commit).
