dirstate-tree: Add `WithBasename` wrapper for `HgPath`

In the tree-shaped dirstate we want to have nodes representing files or
directories, where directory nodes contain a map associating "base" names
to child nodes for child files and directories.

Many dirstate operations expect a full path from the repository root, but
re-concatenating string from nested map keys all the time might be expensive.
Instead, `WithBasename` stores a full path for these operations but
behaves as its base name (last path component) for equality and comparison.

Additionally `inclusive_ancestors` provides the successive map keys
that are needed when inserting a new dirstate node at a given full path.

== New Features ==

 * Windows will process hgrc files in %PROGRAMDATA%\Mercurial\hgrc.d.


== New Experimental Features ==


== Bug Fixes  ==

 * The `indent()` template function was documented to not indent empty lines,
   but it still indented the first line even if it was empty. It no longer does
   that.

== Backwards Compatibility Changes ==


== Internal API Changes ==

 * Matcher instances no longer have a `explicitdir` property. Consider
   rewriting your code to use `repo.wvfs.isdir()` and/or
   `ctx.hasdir()` instead. Also, the `traversedir` property is now
   also called when only `explicitdir` used to be called. That may
   mean that you can simply remove the use of `explicitdir` if you
   were already using `traversedir`.

 * The `revlog.nodemap` object have been merged into the `revlog.index` object.
   * `n in revlog.nodemap` becomes `revlog.index.has_node(n)`,
   * `revlog.nodemap[n]` becomes `revlog.index.rev(n)`,
   * `revlog.nodemap.get(n)` becomes `revlog.index.get_rev(n)`.

 * `copies.duplicatecopies()` was renamed to
   `copies.graftcopies()`. Its arguments changed from revision numbers
   to context objects. It also lost its `repo` and `skip` arguments
   (they should no longer be needed).
