dirstate: cover each dirstate version when testing for status race
Previously we were only testing it with the default (dirstate-v1 currently).
Now we explicitly test each variant.

dirstate: test a `hg status` raced by another `hg status`
This shows that `rhg` is misbehaving here.

dirstate: add a way to test races happening during status
We add the `devel.sync.status.pre-dirstate-write-file` config option to easily
test what happens when other operations happen during the window where
`hg status` is done working but has not updated the cache on disk yet.
We introduce the framework for testing such races too, actual tests will be
added in the next changesets. For now the test is only checking dirstate-v1. We
will extend the test coverage later too.
Check test documentation for details.

testing: introduce util function to synchronize concurrent commands on files
This is an extension of mechanisms that the tests have been using for a while.
To be able to also control the execution in Rust, we introduce utility to
perform such `wait_on_file` logic based on some configuration value.
This will be used in the tests introduced in the next changesets.

dirstate: add some debug output when writing the dirstate
This helps debugging Mercurial behavior in the dirstate-v2 case.

This is not that hard to implement and makes our life easier on a regular basis.

dirstate-v2: don't mmap the data file when on NFS
`mmap` on NFS will trigger a SIGBUS when the mmap'ed file is deleted, which
wouldn't work in our case. Also, the performance advantage of using mmap on
NFS is debatable at best.
