py-mercurial: update to 5.3.1.

Regular bug fix release.

Log message:
py-mercurial: update to 5.3.

== New Features ==

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

== 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.

== 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).

Backwards Compatibility Changes
===============================

* The infinitepush extension is believed to be unused, and will be
deleted at the end of 2020 unless users contact
mercurial-devel@mercurial-scm.org.

* 'hg grep' now searches working copy file contents by default. We
recognize this is a significant change from past behavior, but
surveys of large bodies of users indicated nobody used (and almost
nobody understood) the previous no-flags behavior of 'hg grep'.
The new behavior aligns with the behavior most users expected
(including hg's maintainers), which also happens to be the behavior
of 'git grep'. Given that the old behavior was confusing to the
point of being unusable, we were comfortable changing this behavior.

API Changes ===========

* 'mercurial.hg.update*' and 'mercurial.merge.update' now expect
a value from a set of NAMED_CONSTANTS ('merge.UPDATECHECK_*'
constants) rather than a collection of magic strings. As of now,
the values are the same, but code should be prepared for these
values to change in the future.

* 'mercurial.hg.updatetotally' is now more thorough about checking
its 'updatecheck' keyword argument. Previously invalid values would
have used the configured default updatecheck method, but now will
raise ValueError.

* 'mercurial.bookmarks.bmstore' no longer has a convenience method
for looking up changectx instances from a bookmark name. Use
'repo[repo.bookmarks[name]]' intead of 'repo.bookmarks.changectx(name)'.
