with multi interface and pipelining. This test just works and did not repeat
the problem his test code showed, but could still serve as a useful test.

anymore

case 535 and it now runs fine. Again a problem with the pipelining code not
taking all possible (error) conditions into account.

In this way 304 tests out of 304 reported OK.

make sure that a previously used one is killed first (since they re-use the
same .pid file etc)

now runs fine.

but that worked nicely in 7.15.5. I converted it into test case 532 and
fixed the problem.

transfer support

would crash if a bad function sequence was used when shutting down after
using the multi interface (i.e using easy_cleanup after multi_cleanup) so
precautions have been added to make sure it doesn't any more - test case 529
was added to verify.

jar has died and we now instead point out our own version of that
