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.

libssh2 startup.

out a stack overwrite (and the corresponding fix) on 64bit Windows when
dealing with HTTP chunked encoding.

They all now return ssize_t to Curl_write().

Unfortunately, Curl_read() is in a sorrier state but it too would benefit from
a similar cleanup.

Versions, not to ./Versions and indentation improvments

2006. It turned out we wrongly assumed that the connection cache was present
when tearing down a connection.

multi interface, but I could also repeat it doing multiple sequential ones
with the easy interface. Using Ciprian's test case, I could fix it.

Add failure checking for servers when fork()ed.

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

CURLOPT_VERBOSE set to non-zero, you still got a few debug messages from the
SSL handshake. This is now stopped.

wrong error message in the error message buffer.

This was possible on debug c-ares enabled builds when both CURL_MEMDEBUG
and CARES_MEMDEBUG environment variables were set. Leading to a file handle
leak even when both variables had the same value, and wierd test suite
results when different.

KNOWN_BUGS #25, which happens when a proxy closes the connection when
libcurl has sent CONNECT, as part of an authentication negotiation. Starting
now, libcurl will re-connect accordingly and continue the authentication as
it should.

a fatal bug so we must require 1.3.2 to get flawless functionality with c-ares.

behaviour some versions of IRIX exhibit of committing suicide on big
mallocs instead of just returning a friendly null pointer

fix closing of fd's when limit is reached
