dirstate-v2: Add support when Rust is not enabled...
dirstate-v2: Add support when Rust is not enabled This wires into `dirstatemap` the parser and serializer added in previous changesets. The memory representation is still the same, with a flat `dict` for `DirstateItem`s and another one for copy sources. Serialization always creates a new dirstate-v2 data file and does not support (when Rust is not enabled) appending to an existing one, since we don’t keep track of which tree nodes are new or modified. Instead the tree is reconstructed during serialization. Differential Revision: https://phab.mercurial-scm.org/D11520

Issue1790: dirstate entry locked into unset if file mtime is set into
the future
Prepare test repo:
$ hg init u
$ cd u
$ echo a > a
$ hg add
adding a
$ hg ci -m1
Set mtime of a into the future:
$ touch -t 203101011200 a
Status must not set a's entry to unset (issue1790):
$ hg status
$ hg debugstate
n 644 2 2031-01-01 12:00:00 a
Test modulo storage/comparison of absurd dates:
#if no-aix
$ touch -t 195001011200 a
$ hg st
$ hg debugstate
n 644 2 2018-01-19 15:14:08 a
