Changelog entry for #1396:
- Merge #1396: Log Linux thread ID.
- On Linux systems log the system-wide unique thread ID instead of
Unbound's internal thread counter.
- Introduce the 'log-thread-id' configuration option to manage logging
the system-wide Linux thread ID for easier debugging with system
tools.

Do not initialize quic_table unless it is enabled (#1381)
* Do not initialize quic_table unless it is enabled
Fedora in FIPS mode might fail to initialize ngtcp2 library, because
some ciphers desired are not available.
Make it possible to skip initialization by setting explicitly quic_port
to 0. Unless we have some listeners for port 853 configured, skip its
initialization as well.
- Fix edns subnet, that scope zero queries, when there is a
subquery without subnet, and the forward-no-cache or
stub-no-cache option is set, it is not stored in cache due to
the forward or stub option.
This has the changelog entry and test.

- simdzone-zone-load, remove config.h.in from the repository, it is generated
by autoreconf, since that has to be called to initialise the simdzone repo.
Add config.h.in to gitignore.
- simdzone-zone-load, remove install-sh from the repository, the configure.ac
requires it, and it is pulled in with autoreconf -fi, the configure script
checks and warns when it is missing, or if the simdzone module is missing.
Add install-sh to gitignore.
- simdzone-zone-load, remove configure, aclocal.m4, ltmain.sh, config.guess,
and config.sub from the repository. Because of the simdzone submodule,
the repository needs to have autoreconf -fi for it.
- Fix http2 drop handling to clear the postpone_drop state so that
other streams on the http2 session are not affected by a drop,
and can clean up properly if also dropped. Fix http2 send reply
so that when there is a send failure is does not recurse into
the mesh functions and also does not drop the connection due to
the condition of one stream.
- Additional fix for CVE-2025-11411 (possible domain hijacking attack),
to include YXDOMAIN and non-referral nodata answers in the mitigation as
well, reported by TaoFei Guo from Peking University, Yang Luo and JianJun
Chen from Tsinghua University.
Changelog note for #1375, and lock for lockchecks and ifdef for compile fix.
- Merge #1375: Copy DNSTAP changes from daemon to workers after
fast_reload.

Copy DNSTAP changes from daemon to workers after fast_reload (#1375)
- On fast_reload, the identity and version strings are always freed and
reallocated as part of dt_apply_cfg(). Add fr_worker_pickup_dnstap_changes()
to copy any changes from daemon to workers.

Mesh reply counters (#1374)
* Statistics counter for number of queries dropped by limit on reply addresses
Request list entries can be associated with multiple pending "reply
addresses". Basically each request list entry keeps its own list of
clients that should receive the response once the recursion is finished.
This requires keeping allocations around for each client, and there is
a global limit on the number of *additional* reply addresses that can
be allocated. (Each new request list entry seems to get its own initial
reply address which is not counted against the limit.)
This commit adds a statistics counter "num_queries_replyaddr_limit" that
counts the number of incoming client queries that have been dropped due
to the restriction on allocating additional reply addresses. This allows
distinguishing these drops from other kinds of drops.
* Statistics counter for number of mesh reply entries
Request list entries can be associated with multiple pending "reply
addresses". Since there is a limit on the number of additional reply
addresses that can be allocated which can cause incoming queries to be
dropped if exceeded, it would be nice to be able to track this number.
This commit basically exports the mesh_area's internal counter
`num_reply_addrs` as "threadX.requestlist.current.replies" /
"total.requestlist.current.replies".
- Fix #1366: Infra cache does not work correctly for NAT64, by
moving the NAT64 synthesis from the iterator when selecting a target
address, to the delegation point itself when adding target
addresses.
- Fix #1165, document the possible circular dependency when using
host names instead of IP addresses for name servers in stub/forward
zones and log a warning when spotted in the configuration.
- For #1364, use OPENSSL_VERSION_TEXT instead of OPENSSL_VERSION_NUMBER
for part of the configure script. OPENSSL_VERSION_TEXT is more
consistent across versions.
- unbound.conf man page updates to include a preview of the section
clauses and some reformatting around the use of "clause", "option"
and "attributes".
