1) the check for winssl needs to come before nss check
2) the SSL checks must begin with a new if or else we will
never find any SSL lib with MinGW.

This is a MSYS/MinGW-only warning; full warning text is:
Use of uninitialized value in numeric gt (>) at ../../curl/tests/runtests.pl line 2227.

Fixed 6 bugs, added 3 contributors

In many states the easy_conn pointer is referenced and just assumed to
be working. This is an added extra check since analyzing indicates
there's a risk we can end up in these states with a NULL pointer there.

It should return PARAM_NO_MEM if the strdup fails. Spotted by

Spotted by clang-analyzer. The return code was never checked, just
stored.

va_end() needs to be used after va_start() and we don't normally use
Curl_ prefixes for purely static functions.

This avoids false positives from clang's scan-build.

Test 1409 and 1410 verifies the stricter numeric option parser
introduced the other day in commit f2b6ebed.

I made "connmon" not get initialized properly before use, and I use the
big hammer and make sure we always clear the entire struct to avoid any
problem like this in the future.

Two commits ago, we fixed a bug where the connction would be closed
prematurely after a HEAD. Now I added connection-monitor to test 48 and
added a second HEAD and make sure that both are sent over the same
connection.

This triggered a failure before the bug fix and now works. Will help us
avoid a future regression of this kind.

This makes verifying easier and makes us more sure curl closes the
connection only at the correct point in time. Adjusted test 206 and 1008
accordingly and updated the docs for it.

A HEAD response has no body length and gets the headers like the
corresponding GET would so it should not get closed after the response
based on the same rules. This mistake caused connections that did HEAD
to get closed too often without a valid reason.

Reported by: Eelco Dolstra

Updated .gitignore for NetWare created files.

1 - str2offset() no longer accepts negative numbers since offsets are by
nature positive.

2 - introduced str2unum() for the command line parser that accepts
numericals which are not supposed to be negative, so that it will
properly complain on apparent bad uses and mistakes.

Since the order of the cookies is sorted by the length of the paths,
having them on the same path length will make the test depend on what
order the qsort() implementation will put them. As seen in the
windows/msys output posted by Guenter in this posting:

The function https_getsock was only implemented properly when USE_SSLEAY
or USE_GNUTLS is defined, but it is also necessary for USE_SCHANNEL.

The problem occurs when Curl_read_plain or Curl_write_plain returns
CURLE_AGAIN. In that case CURL_OK is returned to the multi-interface an
the used socket is set to state CURL_POLL_REMOVE and the easy-state is
set to CURLM_STATE_PROTOCONNECT. This is fine, because later the socket
should be set to CURL_POLL_IN or CURL_POLL_OUT via multi_getsock. That's
where https_getsock is called and doesn't return any sockets.
