NTLM tests: boost coverage by forcing the hostname

A shared library tests/libtest/.libs/lihostname.so is preloaded in NTLM
test-cases to override the system implementation of gethostname(). It
makes it possible to test the NTLM authentication for exact match, and
this way test the implementation of MD4 and DES.

If LD_PRELOAD doesn't work, a debug build willl also workk as debug
builds are now made to prefer a specific environment variable and will
then return that content as host name instead of the actual one.

Kamil wrote the bulk of this, Daniel Stenberg polished it.

http_ntlm: add support for NSS

When configured with '--without-ssl --with-nss', NTLM authentication
now uses NSS crypto library for MD5 and DES. For MD4 we have a local
implementation in that case. More details are available at
https://bugzilla.redhat.com/603783

In order to get it working, curl_global_init() must be called with
CURL_GLOBAL_SSL or CURL_GLOBAL_ALL. That's necessary because NSS needs
to be initialized globally and we do so only when the NSS library is
actually required by protocol. The mentioned call of curl_global_init()
is responsible for creating of the initialization mutex.

There was also slightly changed the NSS initialization scenario, in
particular, loading of the NSS PEM module. It used to be loaded always
right after the NSS library was initialized. Now the library is
initialized as soon as any SSL or NTLM is required, while the PEM module
is prevented from being loaded until the SSL is actually required.

remove the CVSish $Id$ lines

Allow compilation even when OpenSSL has been configured without MD4 support.

Julien Chaffraix corrected bad #elif lines to silence warnings

libcurl's memory.h renamed to curl_memory.h

Fix NTLM authentication memory leak on SSPI enabled Windows builds

Indentation fixes, untabify and related whitespace-cleanup. No code changed.

Added support for Digest and NTLM authentication using GnuTLS.

ensure that we use the ANSI version functions

Introduced curl_sspi.c and curl_sspi.h for the implementation of functions
Curl_sspi_global_init() and Curl_sspi_global_cleanup() which previously were

Introduced curl_sspi.c and curl_sspi.h for the implementation of functions
Curl_sspi_global_init() and Curl_sspi_global_cleanup() which previously were
named Curl_ntlm_global_init() and Curl_ntlm_global_cleanup() in http_ntlm.c
Also adjusted socks_sspi.c to remove the link-time dependency on the Windows
SSPI library using it now in the same way as it was done in http_ntlm.c.

Fixed a couple more locale-dependent toupper conversions, mainly for
clarity. This does fix one problem that causes ;type=i FTP URLs

Fixed a couple more locale-dependent toupper conversions, mainly for
clarity. This does fix one problem that causes ;type=i FTP URLs
to fail in the Turkish locale when CURLOPT_PROXY_TRANSFER_MODE is
used (test case 561)

Added tests 561 and 1092 through 1094 to test various combinations
of ;type= and ;mode= URLs that could potentially fail in the Turkish
locale.

moved the Curl_raw_ functions into the new lib/rawstr.c file for easier curlx_
inclusion by the curl tool without colliding with the curl_strequal functions.

fix compiler warning: function declaration isn't a prototype

Made some variables const which eliminated some casts

Adjust usage of conditional definition of USE_OPENSSL

libcurl internal base64.h header file renamed to curl_base64.h

(http://curl.haxx.se/bug/view.cgi?id=2042430) with a patch. "NTLM Windows
SSPI code is not thread safe". This was due to libcurl using static
variables to tell wether to load the necessary SSPI DLL, but now the loading
has been moved to the more suitable curl_global_init() call.

removed space after if and while before the parenthesis for better source code
consistency

Enabled a few more gcc warnings with --enable-debug. Renamed a few
variables to avoid shadowing global declarations.

Fixed some minor type mismatches and missing consts mainly found by splint.

NTLMFLAG_NEGOTIATE_UNICODE, we need to filter it off because libcurl doesn't
