Add hyperlinks from program options to definition in man pages
Side-effect of hyperlinking is that typos in program and option names
are now detected by Sphinx.

Candidate -options were detected using:
    find -name *.rst | xargs grep '``-[^`]'
and then modified from ``-o`` to :option:`-o` using regex
    s/``\(-[^`]\+\)``/:option:`\1`/
+ manual modifications where necessary.

Non-hyphenated options were detected by looking at context around
program names:
    find bin -name *.rst | xargs -I{} -n1 basename {} .rst | sort -u
and grepping for program name with trailing whitespace.

Stand-alone program names like ``named`` are not hyperlinked in this
commit.

Notes for BIND 9.17.11
----------------------
New Features
~~~~~~~~~~~~
- ``dig`` has been extended to support DNS-over-HTTPS (DoH) queries,
using ``dig +https`` and related options. :gl:`#1641`
- A new ``purge-keys`` option has been added to ``dnssec-policy``. It
sets the period of time that key files are retained after becoming
obsolete due to a key rollover; the default is 90 days. This feature
can be disabled by setting ``purge-keys`` to 0. :gl:`#2408`
Feature Changes
~~~~~~~~~~~~~~~
- To prevent users from inadvertently configuring unencrypted
DNS-over-HTTPS (DoH) in BIND 9, ``listen-on`` and ``listen-on-v6``
statements using the ``http`` parameter must now also specify the
``tls`` parameter. ``tls none`` can be used to explicitly allow
unencrypted HTTP connections. :gl:`#2472`
- ``http default`` can now be specified in ``listen-on`` and
``listen-on-v6`` statements to use the default HTTP endpoint of
``/dns-query``. It is no longer necessary to include an ``http``
statement in ``named.conf`` unless overriding this value. :gl:`#2472`
Bug Fixes
~~~~~~~~~
- Zone journal (``.jnl``) files created by versions of ``named`` prior
to 9.16.12 were no longer compatible; this could cause problems when
upgrading if journal files were not synchronized first. This has been
corrected: older journal files can now be read when starting up. When
an old-style journal file is detected, it is updated to the new format
immediately after loading.
Note that journals created by the current version of ``named`` are not
usable by versions prior to 9.16.12. Before downgrading to a prior
release, users are advised to ensure that all dynamic zones have been
synchronized using :option:`rndc sync -clean <rndc sync>`.
A journal file's format can be changed manually by running
``named-journalprint -d`` (downgrade) or ``named-journalprint -u``
(upgrade). Note that this *must not* be done while ``named`` is
running. :gl:`#2505`
- ``named`` crashed when it was allowed to serve stale answers and
``stale-answer-client-timeout`` was triggered without any (stale) data
available in the cache to answer the query. :gl:`#2503`
- If an outgoing packet exceeded ``max-udp-size``, ``named`` dropped it
instead of sending back a proper response. To prevent this problem,
the ``IP_DONTFRAG`` option is no longer set on UDP sockets, which has
been happening since BIND 9.17.6. :gl:`#2466`
- NSEC3 records were not immediately created when signing a dynamic zone
using ``dnssec-policy`` with ``nsec3param``. This has been fixed.
:gl:`#2498`
- A memory leak occurred when ``named`` was reconfigured after adding an
inline-signed zone with ``auto-dnssec maintain`` enabled. This has
been fixed. :gl:`#2041`
- An invalid direction field (not one of ``N``, ``S``, ``E``, ``W``) in
a LOC record resulted in an INSIST failure when a zone file containing
such a record was loaded. :gl:`#2499`
- If an invalid key name (e.g. ``a..b``) was specified in a
``primaries`` list in ``named.conf``, the wrong size was passed to
``isc_mem_put()``, which resulted in the returned memory being put on
the wrong free list and prevented ``named`` from starting up. This has
been fixed. :gl:`#2460`
- ``libtool`` was inadvertently introduced as a build-time requirement
when the build system was revamped in BIND 9.17.2. This unnecessarily
prevented hosts without that tool from building BIND 9 from source
tarballs. A standalone ``libtool`` script no longer needs to be
present in ``PATH`` to build BIND 9 from a source tarball. :gl:`#2504`
