dirstate-v2: Separate HAS_FILE_MTIME and HAS_DIRECTORY_MTIME flags
Previously the same flag was used, with its meaning based on whether the node
otherwise identifies a file tracked anywhere.
In addition to being more explicit, this enables storing a directory mtime
if a given path used to be tracked in a parent commit (so the dirstate still
has data about it) but became a directory in the working copy.
(However this is not done yet as it would require a larger change,
replacing the `dirstate_map::NodeData` enum with struct fields.)

== New Features == * `hg config` now has a `--source` option to show where each configuration value comes from. * Introduced a command (debug-repair-issue6533) to repair repositories affected by issue6528 where certain files would show up as modified even if they were clean due to an issue in the copy-tracing code. == Default Format Change == These changes affect newly created repositories (or new clone) done with Mercurial 5.9. == New Experimental Features == * A `changelogv2` format has been introduced. It is not ready for use yet, but will be used later to address some of the weaknesses of the current revlog format. * Initial experiment and support for `dirstatev2`, a new dirstate format that addresses some of the weaknesses of the current dirstate format. Python + C and Rust support are being implemented, but the Rust solution is the one currently getting the attention for performance. * Initial support for `rhg status`. `rhg` is the Rust wrapper executable for hg that shortcuts some commands for faster execution speed. == Bug Fixes == * Fixed a regression (in 5.9.1) introduced in 5.9 when cloning repos with deep filenames * Fixed detection of directories becoming symlinks, but only when using the Rust extensions. * Fixed ignore and include not composing in the Rust status * `hg commit --interactive` now handles deselecting edits of a rename * Fixed a case where `hg evolve` gives different results when interrupted * Fixed a memory leak in phases computation * `histedit` and `shelve` don't swallow errors when updating the working copy anymore * Improve error message when detecting content-divergence with a hidden common predecessor * No longer re-order parents in filelog, see issue6533 * Fix revisions affected by issue6533 on the fly during exchange * Many Windows fixes for stability and py3 compatibility improvements * Many other miscellaneous fixes == Backwards Compatibility Changes == == Internal API Changes == The Dirstate API have been updated as the previous function leaked some internal details and did not distinguish between two important cases: "We are changing parent and need to adjust the dirstate" and "some command is changing which file is tracked". To clarify the situation: * the following functions have been deprecated, - `dirstate.add`, - `dirstate.normal`, - `dirstate.normallookup`, - `dirstate.merge`, - `dirstate.otherparent`, - `dirstate.remove`, - `dirstate.drop`, - `dirstateitem.__getitem__`, * these new functions are added for the "adjusting parents" use-case: - `dirstate.update_file`, - `dirstate.update_file_p1`, * these new function are added for the "adjusting wc file" use-case": - `dirstate.set_tracked`, - `dirstate.set_untracked`, - `dirstate.set_clean`, - `dirstate.set_possibly_dirty`, See inline documentation of the new functions for details. * Additionally, the following have been deprecated: - `urlutil.getpath` function - `localrepository.updatecaches`' `full` argument * The following have been removed: - `revlog.revlogio` has been removed
