Michał Kępień 902e4482e0 Add a Sphinx role for linking GitLab issues/MRs
Define a :gl: Sphinx role that takes a GitLab issue/MR number as an
argument and creates a hyperlink to the relevant ISC GitLab URL.  This
makes it easy to reach ISC GitLab pages directly from the release notes.

Make all GitLab references in the release notes use the new Sphinx role.

Notes for BIND 9.16.7
---------------------
New Features
~~~~~~~~~~~~
- Add a new ``rndc`` command, ``rndc dnssec -checkds``, which signals to
``named`` that a DS record for a given zone or key has been published
or withdrawn from the parent. This command replaces the time-based
``parent-registration-delay`` configuration option. :gl:`#1613`
- Log when ``named`` adds a CDS/CDNSKEY to the zone. :gl:`#1748`
Bug Fixes
~~~~~~~~~
- In rare circumstances, ``named`` would exit with an assertion failure
when the number of nodes stored in the red-black tree exceeded the
maximum allowed size of the internal hash table. :gl:`#2104`
- Silence spurious system log messages for an EPROTO(71) error code that
was seen on older operating systems, where unhandled ICMPv6 errors
resulted in a generic protocol error being returned instead of a more
specific error code. :gl:`#1928`
- With query name minimization enabled, ``named`` failed to resolve
``ip6.arpa.`` names that had extra labels to the left of the IPv6
part. For example, when ``named`` attempted query name minimization on
a name like ``A.B.1.2.3.4.(...).ip6.arpa.``, it stopped at the
leftmost IPv6 label, i.e. ``1.2.3.4.(...).ip6.arpa.``, without
considering the extra labels (``A.B``). That caused a query loop when
resolving the name: if ``named`` received NXDOMAIN answers, then the
same query was repeatedly sent until the number of queries sent
reached the value of the ``max-recursion-queries`` configuration
option. :gl:`#1847`
- Parsing of LOC records was made more strict by rejecting a sole period
(``.``) and/or ``m`` as a value. These changes prevent zone files
using such values from being loaded. Handling of negative altitudes
which are not integers was also corrected. :gl:`#2074`
- Several problems found by `OSS-Fuzz`_ were fixed. (None of these are
security issues.) :gl:`!3953` :gl:`!3975`
