For some tests, we need to send big data streams (for TCP) or repeated
packets (for UDP), this commits adds `-r` option to packet.pl that sends
the same input <repeats> times using the specified protocol.

Previously .txt files with full backtrace may be identified as a
crashed test:
I:Core dumps were found for the following system tests:
I: core.19948-backtrace.txt
I: shutdown
Now .txt files are removed from the list.
Change 'run.sh.in' to match the core matching pattern in
'testsummary.sh'.

Now that the log message has been printed set the result code to
DNS_R_FORMERR. We don't do this via dns_result_torcode() as we
don't want upstream errors to produce FORMERR if that processing
end with DNS_R_BADTSIG.

Only allow it when explicitly requested (by building with

it was possible for the count_newzones() function to try to
unlock view->new_zone_lock on return before locking it, which
caused a crash on shutdown.

When "rndc reconfig" is run, named first configures a fresh set of views
and then tears down the old views. Consider what happens for a single
view with LMDB enabled; "envA" is the pointer to the LMDB environment
used by the original/old version of the view, "envB" is the pointer to
the same LMDB environment used by the new version of that view:
1. mdb_env_open(envA) is called when the view is first created.
2. "rndc reconfig" is called.
3. mdb_env_open(envB) is called for the new instance of the view.
4. mdb_env_close(envA) is called for the old instance of the view.
This seems to have worked so far. However, an upstream change [1] in
LMDB which will be part of its 0.9.26 release prevents the above
sequence of calls from working as intended because the locktable mutexes
will now get destroyed by the mdb_env_close() call in step 4 above,
causing any subsequent mdb_txn_begin() calls to fail (because all of the
above steps are happening within a single named process).
Preventing the above scenario from happening would require either
redesigning the way we use LMDB in BIND, which is not something we can
easily backport, or redesigning the way BIND carries out its
reconfiguration process, which would be an even more severe change.
To work around the problem, set MDB_NOLOCK when calling mdb_env_open()
to stop LMDB from controlling concurrent access to the database and do
the necessary locking in named instead. Reuse the view->new_zone_lock
mutex for this purpose to prevent the need for modifying struct dns_view
(which would necessitate library API version bumps). Drop use of
MDB_NOTLS as it is made redundant by MDB_NOLOCK: MDB_NOTLS only affects
where LMDB reader locktable slots are stored while MDB_NOLOCK prevents
the reader locktable from being used altogether.

Add a note why we don't have a test case for the issue.
It is tricky to write a good test case for this if our tools are
not allowed to create signatures for unsupported algorithms.

In [RT #43367], the BIND 9 changed the strictness of address / prefix
length checks:
Check prefixes in acls to make sure the address and
prefix lengths are consistent. Warn only in
BIND 9.11 and earlier.
Unfortunately, a regression slipped in and the check was made an error
also in the BIND 9.11. This commit fixes the regression, but turning
the error into a warning.
Add a system test that counts how many address fetches are made
for different numbers of NS records and checks that the number
are successfully limited.

that the records have been removed is commenced. Loop several times to
prevent false negative.
