RTD style default never wraps <th> and <td> elements and that just does
not work for real sentences or any other long lines.
We can reconsider styling some tables separately, but at the moment we
do not have use for tables with long but unwrappable lines so it's
easier to allow wrapping globally.

When processing a catalog zone update, skip processing records with
DNSSEC-related and ZONEMD types, because we are not interested in them
in the context of a catalog zone, and processing them will fail and
produce an unnecessary warning message.

The perl modifation code for keyless.example was not deterministic
(/NXT/ matched part of signature) resulting in different error
strings being returned. Replaced /NXT/ with /A RRSIG NSEC/ and
updated expected error string,

The current implementation of isc_queue uses Michael-Scott lock-free
queue that in turn uses hazard pointers. It was discovered that the way
we use the isc_queue, such complicated mechanism isn't really needed,
because most of the time, we either execute the work directly when on
nmthread (in case of UDP) or schedule the work from the matching
nmthreads.
Replace the current implementation of the isc_queue with a simple locked
ISC_LIST. There's a slight improvement - since copying the whole list
is very lightweight - we move the queue into a new list before we start
the processing and locking just for moving the queue and not for every
single item on the list.
NOTE: There's a room for future improvements - since we don't guarantee
the order in which the netievents are processed, we could have two lists
- one unlocked that would be used when scheduling the work from the
matching thread and one locked that would be used from non-matching
thread.

Typing from libuv structure to isc_region_t is not possible, because
their sizes differ on 64 bit architectures. Little endian machines seems
to be lucky and still result in test passed. But big endian machine such
as s390x fails the test reliably.
Fix by directly creating the buffer as isc_region_t and skipping the
type conversion. More readable and still more correct.

Make sure that the key structure is valid when calling the following
functions:
- dst_key_setexternal
- dst_key_isexternal
- dst_key_setmodified
- dst_key_ismodified
This commit is adapted because 9.16 has a different approach
of deconsting the variable.

Setting the sock->write_timeout from the TCP, TCPDNS, and TLSDNS send
functions could lead to (harmless) data race when setting the value for
the first time when the isc_nm_send() function would be called from
thread not-matching the socket we are sending to. Move the setting the
sock->write_timeout to the matching async function which is always
called from the matching thread.

Clang added support for the gcc-style fallthrough
attribute (i.e. __attribute__((fallthrough))) in version 10. However,
__has_attribute(fallthrough) will return 1 in C mode in older versions,
even though they only support the C++11 fallthrough attribute. At best,
the unsupported attribute is simply ignored; at worst, it causes errors.
The C2x fallthrough attribute has the advantages of being supported in
the broadest range of clang versions (added in version 9) and being easy
to check for support. Use C2x [[fallthrough]] attribute if possible, and
fall back to not using an attribute for clang versions that don't have
it.

When autoconf was checking for libuv features, the LIBUV_CFLAGS was not
added to CFLAGS and LIBUV_LIBS to LIBS which resulted in false
negatives.
Use AX_SAVE_FLAGS and AX_RESTORE_FLAGS to temporarily add LIBUV_CFLAGS
and LIBUV_LIBS to their respective variables.

7249bad7 introduced the -c option to stat(1) command, but BSD systems
do not know about it. Replace the stat(1) command with a PERL script
that achieves the same.
Why PERL? For consistency purposes, there are more places in the
system test where we use the same method.

Add a new parameter to the dst_key structure, mark a key modified if
dst_key_(un)set[bool,num,state,time] is called. Only write out key
files during a keymgr run if the metadata has changed.
(cherry picked from commit 1da91b3ab4)
Add a test case that triggers a keymgr run that will not trigger any
metadata changes. Ensure that the last status change of the key files
is unmodified.

when built without libtool, the sample driver in the dyndb
system test runs library intializers that have already been
run, causing the value for isc__trampoline_min to be reset.
wrap the trampoline initialize and shutdown routines under
isc_once_do() to ensure that they are only run once.
Check that the recursing client count is above a reasonable
minimum, as well as below a maximum, so that we can detect
bugs that cause recursion to fail too early or too often.
(cherry picked from commit 8834c44683)
The ns_statscounter_recursclients counter was previously only
incremented or decremented if client->recursionquota was non-NULL.
This was harmless, because that value should always be non-NULL if
recursion is enabled, but it made the code slightly confusing.

The fetchlimit test depends on a resolver continuing to try UDP
and timing out while the client waits for resolution to succeed.
but since commit bb990030 (flag day 2020), a fetch will always
switch to TCP after two timeouts, unless EDNS was disabled for
the query.
This commit adds "edns no;" to server statements in the fetchlimit
resolver, to restore the behavior expected by the test.

Since commit bad5a523c2, when the fetches-per-server quota
was increased or decreased, instead of the value being set to
the newly calculated quota, it was set to the *minimum* of
the new quota or 1 - which effectively meant it was always set to 1.
it should instead have been the maximum, to prevent the value from
ever dropping to zero.
