Release Zulip Server 2.0.5.

Any regex including a match-everything subpattern (.*, .*?, .+, or
.+?) is almost automatically wrong because it fails to disambiguate
when one subpattern should end and another should begin.  Among other
bugs, these kind of regexes tend to be especially prone to denial of
service vulnerabilities through catastrophic backtracking on strings
that fail to match in a large (in this case, exponential) number of
ways.

Lacking a specification to say what characters should actually be
allowed in these subpatterns (this syntax is too different from
CommonMark to be able to precisely apply those rules), I’ve tried to
make reasonable guesses and avoid changing much else.

Because Zulip doesn't store messages until they have successfully been
processed by the Markdown processor, this is not a stored DoS issue.

In general, Zulip protects against the broad category of DoS issues in
Markdown rendering via a timeout managed by another thread.  However,
details of Python's regular expression implementation mean that this
particular issue could prevent the timeout thread from being
scheduled, resulting in this being a DoS issue.

This was fixed in master a few months ago as a side effect of
abe2dab88c (#12979).

-    an existing row for the property/(realm, stream, user)/time with subgroup=None, Django would
-    create a duplicate row.
-
-    In the next migration, we'll add a proper constraint to fix this bug, but
-    we need to fix any existing problematic rows before we can add that constraint.
-
-    We fix this in an appropriate fashion for each type of CountStat object; mainly
