Witold Kręcicki 58db2d1d18 Fix a bug in trust anchors verification. 
We were not reseting the keynode value when iterating over DNSKEYs in
RRSET, so we weren't checking all DNSKEYs against all trust anchors. This
commit fixes the issue by resetting keynode with every loop.

Michał Kępień b50ced528d Fail the "tcp" system test when ans6 fails 
Make the "tcp" system test fail if the Python tool used for establishing
TCP connections (ans6) logs a result different than "OK" after
processing a command sent to it (as that means the tool was unable to
successfully perform the requested action), with the exception of
cleanup errors at the end of the test which can be safely ignored.  Note
that the tool not returning any result at all in 10 seconds is still a
fatal error in all cases.

Witold KręcickiandOndřej Surý 7d93371581 lib/dns/adb.c: don't use more than 64 lock simultaneously when run under TSAN 
- TSAN can't handle more than 64 locks in one thread, lock ADB bucket-by-bucket
   in TSAN mode. This means that the dump won't be consistent but it's good
   enough for testing

 - Use proper order when unlocking adb->namelocks and adb->entrylocks when
   dumping ADB.
