are not, due mainly to the lack of support for XML character entities
(e.g. & => & ).  This will make it easier to validate test files using
tools like xmllint, as well as edit and view them using XML tools.

Check for the .exe extension on mingw32 builds.

Flush the protocol log data so it's immediately available to the test harness.

something went wrong like it got a bad response code back from the server,
libcurl would leak memory. Added test case 538 to verify the fix.

I also noted that the connection would get cached in that case, which
doesn't make sense since it cannot be re-use when the authentication has
failed. I fixed that issue too at the same time, and also that the path
would be "remembered" in vain for cases where the connection was about to
get closed.

responded with a single status line and no headers nor body. Starting now, a
HTTP response on a persistent connection (i.e not set to be closed after the
response has been taken care of) must have Content-Length or chunked
encoding set, or libcurl will simply assume that there is no body.

To my horror I learned that we had no less than 57(!) test cases that did bad
HTTP responses like this, and even the test http server (sws) responded badly
when queried by the test system if it is the test system. So although the
actual fix for the problem was tiny, going through all the newly failing test
cases got really painful and boring.

have proper TERM and INT signal handlers implemented.

be clear of warnings. Uncomment it if this module is further modified.

The "warnings" module requires perl 5.006 or later. Previous perl
versions don't have it and die on missing modules.

If the list has only one item avoid sort subroutine.

server holds not only its two main pids, but also the pidfile of the test
server and the 'slavepidfiles' for ftp* servers. This allows a better control
when stopping servers.

Now from runtests.pl when test servers are stopped they are signalled in
sequence TERM, INT and KILL allowing time in between for them to die. This
will give us a chance of gracefully stopping test servers, which we didn't
have when we were killing them in first instance.

Add failure checking for servers when fork()ed.

Use same code path in 'stopserver' when called with a single or multiple pids.
