The "exitcode" variable is set to 9 if a TCP connection fails, but is
not reset to 0 if a subsequent TCP connection succeeds. This causes dig
to return a non-zero exit code if it succeeds in getting a TCP response
after a retry. Fix by resetting "exitcode" to 0 if connect_done()
receives an event with the "result" field set to ISC_R_SUCCESS.

5019. [cleanup] A message is now logged when ixfr-from-differences is
set at zone level for an inline-signed zone. [GL #470]
(cherry picked from commit 4fb5d072c2)
For inline-signed zones, the value of "ixfr-from-differences" is
hardcoded to:
- "yes" for the raw version of the zone,
- "no" for the signed version of the zone.
In other words, any user-provided "ixfr-from-differences" setting is
effectively ignored for an inline-signed zone. Ensure the user is aware
of that by adding a note to the ARM and logging a message when an
"ixfr-from-differences" option is found at the zone level.

$RANDFILE, i.e. bin/tests/system/random.data, should only be written to
if a system test requires support for cryptography and that file does
not already exist. Otherwise, when multiple system tests are run in
parallel, that file might get truncated due to bin/tools/genrandom.c
using fopen() with mode "w" when writing the destination file. With
unfortunate timing, this may cause system tests employing BIND tools
which need entropy (e.g. dnssec-keygen) to fail.
Make sure bin/tests/system/metadata/tests.sh no longer calls
bin/tools/genrandom since $RANDFILE is guaranteed to already be created
by the time bin/tools/genrandom is currently called because
bin/tests/system/metadata/prereq.sh uses bin/tests/system/testcrypto.sh.
Make sure bin/tests/system/sfcache/prereq.sh only writes to $RANDFILE if
it does not already exist.

A short time window exists between logging the addition of an NSEC3PARAM
record to a zone and committing it to the current version of the zone
database. If a query arrives during such a time window, an unsigned
response will be returned. One of the checks in the "inline" system
test requires NSEC3 records to be present in an answer - that check
would fail in the case described above. Use rndc instead of log
watching for checking whether zone signing and NSEC3 chain modifications
are complete in order to prevent intermittent "inline" system test
failures.

While "rndc reload" causes dns_zone_asyncload() to be called for the
signed version of an inline-signed zone, the subsequent zone_load() call
causes the raw version to be reloaded from storage. This means that
DNS_ZONEFLG_LOADPENDING gets set for the signed version of the zone by
dns_zone_asyncload() before the reload is attempted, but zone_postload()
is only called for the raw version and thus DNS_ZONEFLG_LOADPENDING is
cleared for the raw version, but not for the signed version. This in
turn prevents zone maintenance from happening for the signed version of
the zone.
Until commit 749b3cacfc, this problem
remained dormant because DNS_ZONEFLG_LOADPENDING was previously
immediately, unconditionally cleared after zone loading was started
(whereas it should only be cleared when zone loading is finished or an
error occurs). This behavior caused other issues [1] and thus had to be
changed.
Fix reloading inline-signed zones by clearing DNS_ZONEFLG_LOADPENDING
for the signed version of the zone once the raw version reload
completes. Take care not to clear it prematurely during initial zone
load. Also make sure that DNS_ZONEFLG_LOADPENDING gets cleared when
zone_postload() encounters an error or returns early, to prevent other
scenarios from resulting in the same problem. Add comments aiming to
help explain code flow.

5014. [bug] Signatures loaded from the journal for the signed
version of an inline-signed zone were not scheduled for
refresh. [GL #482]
(cherry picked from commit b3b1a9081b)
When an inline-signed zone is loaded, the master file for its signed
version is loaded and then a rollforward of the journal for the signed
version of the zone is performed. If DNS_JOURNALOPT_RESIGN is not set
during the latter phase, signatures loaded from the journal for the
signed version of the zone will not be scheduled for refresh. Fix the
conditional expression determining which flags should be used for the
dns_journal_rollforward() call so that DNS_JOURNALOPT_RESIGN is set when
zone_postload() is called for the signed version of an inline-signed
zone.
Extend bin/tests/system/stop.pl so that it can use "rndc halt" instead
of "rndc stop" as the former allows master file flushing upon shutdown
to be suppressed.
