harder to figure out its name to parse it after a test has run).

Also made sure we only use valgrind for the actual test command command lines,
not when for example running curl to detect if there are any already running

the control connection. To avoid the risk that it will "hang" waiting for
the QUIT response. Added test case 161 to verify this.

we won't try to QUIT the control connection and risk "hanging" waiting for
a response. Test case 161 verifies this. The quit-sending function was
also made static.

we tell valgrind to use that to send the logfile to

We got no data and we attempted to re-use a connection. This might happen if
the connection was left alive when we were done using it before, but that was
closed when we wanted to read from it again. Bad luck. Retry the same request
on a fresh connect!

Deleted the sockerror variable again, it serves no purpose anymore.
