md4: No need for the NTLM code to call Curl_md4it() for each TLS library
As the NTLM code no longer calls any of TLS libraries' specific MD4
functions, there is no need to call this function for each #ifdef.

Steve Holme cd15acd0ec ntlm: Support the NT response in the type-3 when OpenSSL doesn't include MD4
Just like we do for mbed TLS, use our local implementation of MD4 when
OpenSSL doesn't support it. This allows a type-3 message to include the
NT response.

snprintf: renamed and we now only use msnprintf()
The function does not return the same value as snprintf() normally does,
so readers may be mislead into thinking the code works differently than
it actually does. A different function name makes this easier to detect.

pkubaj 7c96f6a14b ntlm: Remove redundant ifdef USE_OPENSSL
lib/curl_ntlm.c had code that read as follows:

  #ifdef USE_OPENSSL
  # ifdef USE_OPENSSL
  # else
  # ..
  # endif
  #endif

Remove the redundant USE_OPENSSL along with #else (it's not possible to
reach it anyway). The removed construction is a leftover from when the
SSLeay support was removed.

Daniel Gustafsson 94400f32e9 all: Refactor malloc+memset to use calloc
When a zeroed out allocation is required, use calloc() rather than
malloc() followed by an explicit memset(). The result will be the
same, but using calloc() everywhere increases consistency in the
codebase and avoids the risk of subtle bugs when code is injected
between malloc and memset by accident.

Viktor Szakats 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.

NTLM: check for features with #ifdef instead of #if
Feature defines are normally checked with #ifdef instead of #if in the rest of

Daniel Stenberg 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.

David Benjamin 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!)

Dan Fandrich 35648f2e79 curl_memory: make curl_memory.h the second-last header file loaded

Daniel Stenberg 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.
