Fixes an issue where failing to reconfigure/reload the server would prevent to preserved the views caches on the subsequent server reconfiguration/reload.
Closes#5523
Merge branch 'colin/fix-cache-revert' into 'main'
See merge request isc-projects/bind9!10984
If the server is reloaded, new views are created and preexisting cache
is attached to those _but_ something goes wrong later, the previous
views are restored but the previous cache list is destroyed. This makes
the subsequent reload to drop the existing cache. This fixes it by
avoiding a mutation of the old cache list.
A named bug scrap the cache on a second reload after an initial reload
failure. Adds a test checking that the cache is preserved between server
reconfiguration/reloads even if it fails at some point (after attempting
to re-use the cache) and the server is re-loaded later.
The dns_qpcache already had all the namespace changes needed to put the
normal data and auxiliary NSEC data into a single tree. Remove the
extra nsec QP trie and use the single QP trie for all the cache data.

As we removed the ability to count nodes in the auxiliary trees (because
there are no auxiliary trees), we can also cleanup the API and
associated enum type (dns_dbtree_t).

The dbiterator_{last,prev} functions are not used in the cache, and the
implementation would get quite complicated when we squash the main and
nsec trees together. It's easier to just not implement these.
We would prefer if explicit $ORIGIN is used only for root zone and
nothing else, solely to avoid zone files named "..db". For all other
zones the file name should match zone name.
The dns_qpmulti_memusage() causes assertion failure when called on

remove the dns_db_locknode() and _unlocknode() calls, so that callers no
longer have the ability to directly manipulate the internal locking of
cache and zone databases.
if the dns_db_getoriginnode() call is not implemented, we can
fall back to running dns_db_findnode() on the database origin.
we now only implement getoriginnode directly in databases where
it's clearly faster than the fallback implementation would be.
dns_db_issecure() and dns_db_nodecount() return false and 0,
respectively, if they are not implemented, so there's no need to
have implementation functions that only return false and 0.
dns_rdataset_clearprefetch() performs an atomic operation,
so it didn't actually need to lock the database node.
dns_rdataset_settrust() updates header->trust; this is also
now atomic, so it doesn't need to lock the node now either.
the dns_db_findext and _findnodeext calls are extended versions
of dns_db_find and _findnode, which take additional arguments for
client information in order to support ECS. previously, database
implementations could support either API call, with cross-compatibility
so that, for example, dns_db_findext() could call a find implementation
if findext was not implemented, and dns_db_find() could call findext
if find was not implemented.
this has now been simplified. the find and findnodeext implementations
now support client info. all database implementations will now provide
these calls. implementations which do not support ECS will simply
ignore the clientinfo and clientinfomethods parameters.
this only affects the underlying implementation; callers will still
use the same interface. dns_db_find() and dns_db_findnode() are now
macros which pass NULL to the clientinfo parameters, so that callers
don't have to do so explicitly. dns_db_findext() and dns_db_findnodeext()
are still available for callers that do wish to pass clientinfo pointers.
this function's purpose was to populate the "CacheBuckets" statistic,
but there are no databases left that implemented it, so the return
value was always 0. "CacheBuckets" has now been removed from the
statistics, and the dns_db_hashsize() API call has been removed.
the rdataset method implementation functions in dns/rdatalist.c (i.e.,
dns_rdatalist_first, _next, etc) are not meant to be called directly;
they're called via dns_rdataset_first(), dns_rdataset_next(), etc.
in dnssec-ksr.c, a list-based rdataset was iterated using these
functions. this has been fixed, and the functions have been renamed
to use the `dns__` prefix as a signal that they aren't meant to be
used outside the rdataset implementation.
The current code would fail during the write transaction. The first
header would not match the search->serial and the node might be
incorrectly detected as inactive.

Simplify the implementation around the database ownercase. Remove the
dns_rdataset_setownercase() implementation for the slabheaders and only
allow setting ownercase on rdatalists and rdatasets. The ownercase in
the database can now be set only with dns_db_addrdataset() by passing
rdataset with correctly set ownercase.

Since !10959 `dns_zone_gethooktable()` is only called once per query,
and the suspicion (from perflab analysis) that this (simple, as just
returning a pointer) call was slowing things down (perhaps because of
code locality reasons?) doesn't matter anymore. So even if !10959
inlined it, it shouldn't matter anymore.

Sphinx's smartquotes feature was rewriting -- to en-dash, "" to proper
English quotes etc. This was messing up syntax at unpredictable places.
Disable this feature instead of attempting to escape all the places in
the manual.
The new order hopefully reflects likelihood of someone reading from start
to the end:

Merging !10483 caused a performance regression because the zone hooktable had to be looked up every time a hook point was reached, even if no zone plugins were configured. We now look up the zone hooktable when a zone is attached to the query context, and keep a pointer to it until the qctx is destroyed.

query_reset() is called during query initialization, but the only
time the NS_QUERY_SETUP hook runs is when it's called from
query_cleanup(). it makes more sense to move the hook point to
there and rename it to NS_QUERY_CLEANUP.
this change caused a crash in the unit tests due to the view being
unnecessarily detached before ns__client_reset_cb() was called.
this has also been fixed.
guard the call to the NS_QUERY_RESET hook so it's called only if
the view has been set. If the view is NULL, it means the client has
been reset _before_ the query even started, and no other hook could
have been called, so it doesn't make sense to call this one.
this also enables us to avoid a NULL-check on the qctx->view in the
CALL_HOOK macros.
