pingpong: return error when trying to send without connection
When imap_done() got called before a connection is setup, it would try
to "finish up" and dereffed a NULL pointer.

Test case 1553 managed to reproduce. I had to actually use a host name
to try to resolve to slow it down, as using the normal local server IP
will make libcurl get a connection in the first curl_multi_perform()
loop and then the bug doesn't trigger.

24bba40456 lib/config-win32.h: let SMB/SMBS be enabled with OpenSSL/NSS
The source code is now prepared to handle the case when both
Win32 Crypto and OpenSSL/NSS crypto backends are enabled
at the same time, making it now possible to enable `USE_WIN32_CRYPTO`
whenever the targeted Windows version supports it. Since this
matches the minimum Windows version supported by curl
(Windows 2000), enable it unconditionally for the Win32 platform.

This in turn enables SMB (and SMBS) protocol support whenever
Win32 Crypto is available, regardless of what other crypto backends
are enabled.

aaa16f8025 lib/Makefile.m32: allow customizing dll suffixes
- New `CURL_DLL_SUFFIX` envvar will add a suffix to the generated
  libcurl dll name. Useful to add `-x64` to 64-bit builds so that
  it can live in the same directory as the 32-bit one. By default
  this is empty.

- New `CURL_DLL_A_SUFFIX` envvar to customize the suffix of the
  generated import library (implib) for libcurl .dll. It defaults
  to `dll`, and it's useful to modify that to `.dll` to have the
  standard naming scheme for mingw-built .dlls, i.e. `libcurl.dll.a`.

9d3dde37a8 vtls: compare and clone ssl configs properly
Compare these settings in Curl_ssl_config_matches():
- verifystatus (CURLOPT_SSL_VERIFYSTATUS)
- random_file (CURLOPT_RANDOM_FILE)
- egdsocket (CURLOPT_EGDSOCKET)

Also copy the setting "verifystatus" in Curl_clone_primary_ssl_config(),
and copy the setting "sessionid" unconditionally.

This means that reusing connections that are secured with a client
certificate is now possible, and the statement "TLS session resumption
is disabled when a client certificate is used" in the old advisory at
https://curl.haxx.se/docs/adv_20170419.html is obsolete.

df7839b68c Set and use more necessary options when some protocols are disabled
When curl and libcurl are built with some protocols disabled, they stop
setting and receiving some options that don't make sense with those
protocols.  In particular, when HTTP is disabled many options aren't set
that are used only by HTTP.  However, some options that appear to be
HTTP-only are actually used by other protocols as well (some despite
having HTTP in the name) and should be set, but weren't. This change now
causes some of these options to be set and used for more (or for all)
protocols. In particular, this fixes tests 646 through 649 in an
HTTP-disabled build, which use the MIME API in the mail protocols.

6f86022df2 ntlm: use strict order for SSL backend #if branches
With the recently introduced MultiSSL support multiple SSL backends
can be compiled into cURL That means that now the order of the SSL

One option would be to use the same SSL backend as was configured
via `curl_global_sslset()`, however, NTLMv2 support would appear
to be available only with some SSL backends. For example, when
eb88d778e (ntlm: Use Windows Crypt API, 2014-12-02) introduced
support for NTLMv1 using Windows' Crypt API, it specifically did
*not* introduce NTLMv2 support using Crypt API at the same time.

So let's select one specific SSL backend for NTLM support when
compiled with multiple SSL backends, using a priority order such
that we support NTLMv2 even if only one compiled-in SSL backend can
be used for that.
