Split the "testing basic zone transfer functionality" into primary and
secondary parts to improve forensic logging.

Add is_leaf and send_to_prune_tree to make the logic easier
to understand in cleanup_dead_nodes and decrement_reference.
(cherry picked from commit c6efc0e50f)
In decrement_reference only test node->down if the tree lock
is held. As node->down is not always tested in
decrement_reference we need to test that it is non NULL in
cleanup_dead_nodes prior to removing the node from the rbt
tree. Additionally it is not always possible to aquire the
node lock and reactivate a node when adding parent nodes.
Reactivate such nodes in cleanup_dead_nodes if required.

Before this change, there was a missing blank line between the
negative trust anchors for one view, and the heading line for the next
view. This is because dns_ntatable_totext() omits the last newline.
There is an example of the incorrect output below; the fixed output
has a blank line before "Start view auth".

Ensure BIND is continuously tested on Tumbleweed, a pure rolling release
version of openSUSE. This will allow BIND incompatibilities with latest
upstream versions of its dependencies to be caught more quickly.

5339. [bug] With some libmaxminddb versions, named could erroneously
match an IP address not belonging to any subnet defined
in a given GeoIP2 database to one of the existing
entries in that database. [GL #1552]
(cherry picked from commit a070defb18)
Only comparing the value of the integer passed as the last argument to
MMDB_lookup_sockaddr() against MMDB_SUCCESS is not enough to ensure that
an MMDB lookup was successful - the 'found_entry' field of the
MMDB_lookup_result_s structure returned by that function also needs to
be true or else the remaining contents of that structure should be
ignored as the lookup failed. Extend the relevant logical condition in
get_entry_for() to ensure the latter does not return incorrect MMDB
entries for IP addresses which do not belong to any subnet defined in a
given GeoIP2 database.

musl libc's implementation of catgets() crashes when its first argument
is -1 instead of a proper message catalog descriptor. Prevent that from
happening by making isc_msgcat_get() return the default text if the
prior call to catopen() returns an error.
Make sure carriage return characters are stripped from sed input to
enable the "forward" system test to pass on Windows.
(cherry picked from commit 075613aea4)
Before, the zero system test could get stuck almost infinitely, because
the first test sends > 300 queries with 5 seconds timeout on each in
each pass. If named crashed early, it would took the test more than 4
hours to properly timeout.
This commit introduces a "watchdog" on the dig commands running in the
background and failing the test on timeout, failing any test if any dig
command fails to return successfully, and making the tests.sh script
shellcheck clean.

Using retry_quiet to test that prefetch is disabled instead of a
standard loop with sleep 1 between each iteration.
(cherry picked from commit 994fc2e822)
These two tests were failing basically because in order for prefetching to
happen, the TTL for a given DNS record must be greater than or equal to
the prefetch config value + 9.
The previous TTL for both records was 10, while prefetch value in
configuration was 3, thus making only records with TTL >= 12 elligible
for prefetching.
TTL value for both records was adjusted to the value 13, and prefetch
value was set to 4 (inc by 1), so records with TTL (4 + 9) >= 13 are
elligible for prefetching.
Adjusting prefetch value to 4 gives the test 1 second more to avoid time
problems when sharing resources on a heavy loaded PC.
Also prefetch value in settings is now read by the script and used
by it to corrrectly calculate the amount of time needed to delay before
sending a request to trigger prefetch, adding a bit of flexibility to
fine tune the test in the future.
(cherry picked from commit a711d6f8c0)
The previous test had two problems:
1. It wasn't written specifically for testing what it was supposed to:
prefetch disabled.
2. It could fail in some circunstances if the computer's load is too
high, due to sleeps not taking parallel tests and cpu load into account.
The new test is testing prefetch disabled as follows:
1. It asks for a txt record for a given domain and takes note of the
record's TTL (which is 10).
2. It sleeps for (TTL - 5) = 5 seconds, having a window of 5 seconds to
issue new queries before the record expires from cache.
3. Three(3) queries are executed in a row, with a interval of 1 second
between them, and for each query we verify that the TTL in response is
less than the previous one, thus ensuring that prefetch is disabled (if
it were enabled this record would have been refreshed already and TTL
would be >= the first TTL).
Having a window of 5 seconds to perform 3 queries with a interval of 1
second between them gives the test a reasonable amount of time
to not suffer from a machine with heavy load.
