dirstate: unify format configs Summary: Previously, there are 2 configs: `treedirstate.useinnewrepos` and `format.usetreestate`. They are both related to dirstate format and conflict with each other. This patch unifies them into a single config `format.dirstate`. As we're here, merge `test-fb-hgext-treedirstate-x.t` to `test-dirstate-x.t` if they were previously copied from `test-dirstate-x.t` Reviewed By: markbt Differential Revision: D8393878 fbshipit-source-id: 57abeea22ce732d93205e4d4308923afa90693f4 2018-06-14 03:49:29 +03:00			`#testcases v0 v1 v2`
treestate: make it an option of dirstate backends Summary: Add a config option `format.usetreestate`, which would turn on the new treestate for new repos. Treestate does not need manually maintaining "copymap", "otherparentset", "nonnormalset". The one single tree is the source of truth of everything. So some code like `copymap.pop` etc. are disabled on treestate path.

dirstate: clean up when restoring identical backups When a dirstate backup is restored, it is possible that no actual changes to the dirstate have been made. In this case, the backup is still a hardlink to the original dirstate. Unfortunately, `os.rename` silently fails (nothing happens, and no error occurs) when `src` and `dst` are hardlinks to the same file. As a result, the backup is left lying around. Over time, these files accumulate. When restoring dirstate backups, check if the backup and the dirstate are the same file, and if so, just delete the backup.
