relnotes: add release notes for relevant changes I did since the 5.4 release

After having written the notes, I realized that the added points contain changes
that were part of the 5.4.2 release. These were never included in any release
notes. I asked on IRC whether they should be added to this file or not, but
didn’t get an answer to this question. If they should not be added here, I can
remove them.

instructions to opt into this.
* An experimental config `rewrite.empty-successor` was introduced to control
what happens when rewrite operations result in empty changesets.
== Bug Fixes ==
* For the case when connected to a TTY, stdout was fixed to be line-buffered
on Python 3 (where it was block-buffered before, causing the process to seem
hanging) and Windows on Python 2 (where it was unbuffered before).
* Subversion sources of the convert extension were fixed to work on Python 3.
* Subversion sources of the convert extension now interpret the encoding of
URLs like Subversion. Previously, there were situations where the convert
extension recognized a repository as present but Subversion did not, and
vice versa.
* The empty changeset check of in-memory rebases was fixed to match that of
normal rebases (and that of the commit command).
* The push command now checks the correct set of outgoing changesets for
obsolete and unstable changesets. Previously, it could happen that the check
prevented pushing changesets which were already on the server.

* The absorb extension now preserves changesets with no file changes that can
be created by the commit command (those which change the branch name
compared to the parent and those closing a branch head).

New accessors are provided to detect if any non-public changeset exists
(`hasnonpublicphases`) and get the correponsponding root set
(`nonpublicphaseroots`).
* The `stdin`, `stdout` and `stderr` attributes of the `mercurial.pycompat`
module were removed. Instead, the attributes of same name from the
`mercurial.utils.procutil` module should be used, which provide more
consistent behavior across Python versions and platforms.
