HTTP upload was disconnected:

"What appears to be happening is that my system (Linux 2.6.17 and 2.6.13) is
setting *only* POLLHUP on poll() when the conditions in my previous mail
occur. As you can see, select.c:Curl_select() does not check for POLLHUP. So
basically what was happening, is poll() was returning immediately (with
POLLHUP set), but when Curl_select() looked at the bits, neither POLLERR or
POLLOUT was set. This still caused Curl_readwrite() to be called, which
quickly returned. Then the transfer() loop kept continuing at full speed
forever."

could make the parser more forgiving to accept all the three found

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.

defining HAVE_SIGNAL_H if the header is available.

Added a check in configure that tests if the sig_atomic_t type is
available, defining HAVE_SIG_ATOMIC_T if it is available. Providing
a suitable default in setup_once.h if not available.

Added a check in configure that tests if the sig_atomic_t type is
already defined as volatile, defining HAVE_SIG_ATOMIC_T_VOLATILE
if it is available and already defined as volatile.

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.
