tests: add extension to emulate invoking dirstate.write at the specific time
This extension fakes 'now' for 'parsers.pack_dirstate()' to emulate
invoking 'dirstate.write()' at the specific time, only when
'dirstate.write()' is invoked via functions below:
- 'workingctx._checklookup()' (= 'repo.status()')
- 'committablectx.markcommitted()'
This is useful to reproduce timing critical issues fixed in subsequent
patches.
