streamclone: treat volatile file as "fullfile"
The nodemap related file might change (or get deleted) during the stream clone
in a way incompatible with the streaming process.
So we introduce a new flag for this type of file and integrate it with the
existing `revlog_type` field recently added to `store.walk` returns.
We use that new flat to dispatch such file to the existing mechanism for "atomic
replacement" file for the nodemap docket and datafile. This fix the bugs we have
been adding tests for.
Strictly speaking, the nodemap datafile is happened only a could maybe be used
in a slightly more efficient way, however this is good enough for now.

== 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).
