685ef13057 ntlm: avoid malloc(0) for zero length passwords
It triggers an assert() when built with memdebug since malloc(0) may
return NULL *or* a valid pointer.

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.

5f830eaba0 mbedtls: enable NTLM (& SMB) even if MD4 support is unavailable
In that case, use libcurl's internal MD4 routine. This fixes tests 1013
and 1014 which were failing due to configure assuming NTLM and SMB were
always available whenever mbed TLS was in use (which is now true).

NTLM: check for features with #ifdef instead of #if
Feature defines are normally checked with #ifdef instead of #if in the rest of
the codebase. Additionally, some compilers warn when a macro is implicitly
evaluated to 0 because it is not defined, which was the case here.

4f45240bc8 lib: include curl_printf.h as one of the last headers
curl_printf.h defines printf to curl_mprintf, etc. This can cause
problems with external headers which may use
__attribute__((format(printf, ...))) markers etc.

To avoid that they cause problems with system includes, we include
curl_printf.h after any system headers. That makes the three last
headers to always be, and we keep them in this order:

 curl_printf.h
 curl_memory.h
 memdebug.h

None of them include system headers, they all do funny #defines.

39c803cba2 openssl: remove most BoringSSL #ifdefs.
As of https://boringssl-review.googlesource.com/#/c/6980/, almost all of
BoringSSL #ifdefs in cURL should be unnecessary:

- BoringSSL provides no-op stubs for compatibility which replaces most
  #ifdefs.

- DES_set_odd_parity has been in BoringSSL for nearly a year now. Remove
  the compatibility codepath.

- With a small tweak to an extend_key_56_to_64 call, the NTLM code
  builds fine.

- Switch OCSP-related #ifdefs to the more generally useful
  OPENSSL_NO_OCSP.

The only #ifdefs which remain are Curl_ossl_version and the #undefs to
work around OpenSSL and wincrypt.h name conflicts. (BoringSSL leaves
that to the consumer. The in-header workaround makes things sensitive to
include order.)

This change errs on the side of removing conditionals despite many of
the restored codepaths being no-ops. (BoringSSL generally adds no-op
compatibility stubs when possible. OPENSSL_VERSION_NUMBER #ifdefs are
bad enough!)

35648f2e79 curl_memory: make curl_memory.h the second-last header file loaded
This header file must be included after all header files except
memdebug.h, as it does similar memory function redefinitions and can be
similarly affected by conflicting definitions in system or dependent
library headers.

0f4a03cbb6 free: instead of Curl_safefree()
Since we just started make use of free(NULL) in order to simplify code,
this change takes it a step further and:

- converts lots of Curl_safefree() calls to good old free()
- makes Curl_safefree() not check the pointer before free()

The (new) rule of thumb is: if you really want a function call that
frees a pointer and then assigns it to NULL, then use Curl_safefree().
But we will prefer just using free() from now on.

709cf76f6b openssl: remove all uses of USE_SSLEAY
SSLeay was the name of the library that was subsequently turned into
OpenSSL many moons ago (1999). curl does not work with the old SSLeay
library since years. This is now reflected by only using USE_OPENSSL in
code that depends on OpenSSL.

e95ca7cec9 NTLM: set a fake entropy for debug builds with CURL_ENTROPY set
Curl_rand() will return a dummy and repatable random value for this
case. Makes it possible to write test cases that verify output.

Also, fake timestamp with CURL_FORCETIME set.

Only when built debug enabled of course.

Curl_ssl_random() was not used anymore so it has been
removed. Curl_rand() is enough.

Commit 07b66cbfa4 unfortunately broke native NTLM message support in

type declarations. This commit fixes VC6 and VC7 as they support the
__int64 extension, however, we should consider an additional fix for
other compilers that don't support this.
