1e96fb8dc0 Request exclusive access when crashing via fatal() 
When loading the configuration fails, there might be already other tasks
running and calling OpenSSL library functions.  The OpenSSL on_exit
handler is called when exiting the main process and there's a timing
race between the on_exit function that destroys OpenSSL allocated
resources (threads, locks, ...) and other tasks accessing the very same
resources leading to a crash in the system threading library. Therefore,
the fatal() function needs to request exlusive access to the task
manager to finish the already running tasks and exit only when no other
tasks are running.

a390e261ad Use "set -e" in the "tcp" system test 
Ensure any unexpected failure in the "tcp" system test causes it to be
immediately interrupted with an error to make the aforementioned test
more reliable.  Since the exit code for "expr 0 + 0" is 1, the status
variable needs to be updated using arithmetic expansion.

01a413cecc Fix argument order in assert_int_equal() 
assert_int_equal() calls in bin/tests/system/tcp/tests.sh pass the found
value as the first argument and the expected value as the second
argument, while the function interprets its arguments the other way
round.  Fix argument handling in assert_int_equal() to make sure the
error messages printed by that function are correct.

3e9781087a Allow retries when checking TCP high-water stats 
In the TCP high-water checks, "rndc stats" is run after ans6 reports
that it opened the requested number of TCP connections.  However, we
fail to account for the fact that ns5 might not yet have called accept()
for these connections, in which case the counts output by "rndc stats"
will be off.  To prevent intermittent "tcp" system test failures, allow
the relevant connection count checks to be retried (just once, after one
second, as that should be enough for any system to accept() a dozen TCP
connections under any circumstances).

7d14ea3795 Limit query pipelining within each TCP connection 
Previously, there was no limit to the number of concurrently served
queries over one pipelined TCP connection; an unlimited number of
queries sent over a single TCP connection could have potentially
exhausted the server's resources.
