rebase: skip obsolete commits even if they have pruned successors

Issue 5782 reported that `hg rebase -r <obsolete commit with pruned
successor>` failed with an error saying that it would cause
divergence. Commit b7e2cf114e85 (rebase: do not consider extincts for
divergence detection (issue5782), 2018-02-09) fixed it by letting you
rebase the commit. However, that fix seems inconsistent with how we
handle `hg rebase -r <pruned commit>`. To me, it should make no
difference whether a commit is pruned itself or if it has (only)
pruned successors. This patch changes it so we treat these two kinds
of commits the same way. I let the message we print remain "note: not
rebasing <commit>, it has no successor" even though that last part is
not technically correct for commits with pruned successors. I doubt it
will confuse users.

Differential Revision: https://phab.mercurial-scm.org/D10240

== 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).
