dirstate-v2: actually use sub-second mtime precision
Instead of zero, set the nanoseconds field to its correct value whenever
possible and preserve it across serialization+parsing.

dirstate: ignore sub-second component when either is zero in mtime
When comparing mtimes for equality.
Some APIs simply return zero when more precision is not available.
When comparing values from different sources, if only one is truncated in
that way, doing a simple comparison would cause many false negatives.

dirstate-v2: add a new MTIME_SECOND_AMBIGUOUS flags
This flag will let us use more `mtime` value in the future. For now we have a
minimal handling of the flag at read time, but we will never put ourself in a
situation where we will needs to writes it.
See the flag documentation for details.

dirstate: store mtimes with nanosecond precision in memory
Keep integer seconds since the Unix epoch,
together with integer nanoseconds in the `0 <= n < 1e9` range.
For now, nanoseconds are still always zero.
This commit is about data structure changes.

dirstate: align Rust function name to `need_delay`
The rest of the code use this name. It is not a great name, but it is better to
stay consistent.

dirstate: rename a `very_likely_equal` method to `likely_equal`
No need to oversell it.

backout: backed out changeset 2f2107c01dee
After discussion on the original phab patch, we've decided to wait until
Python 2 support is dropped to do this since the behavior differs for
relatively obscure reasons.

dirstate-v2: preserve the fallback values on disk
When the fallback values are set, they are now read and written to disk.
