Added some bug fixes that I had missed in previous synchronisations.

I suspect this causes compile failures on Solaris:

Bug: http://curl.haxx.se/mail/lib-2014-12/0081.html

url.c:3078: warning: variable 'credentialsMatch' set but not used

parsedate.c:548: warning: 'parsed' may be used uninitialized in this
                 function

As curl_getdate() returns -1 when parsedate() fails we can initialise
parsed to -1.

Worth exploring

There might be one or two memory leaks left in the error paths.

This fixes the test 506 torture test. The internal cookie API really
ought to be improved to separate cookie parsing errors (which may be
ignored) with OOM errors (which should be fatal).

Some websites meanwhile refuse to reply to requests from ancient
browsers like IE6, therefore I've comment out this setting, but
also fixed the string to now fake IE8 if someone enables it.

As Windows based autoconf builds don't yet define USE_WIN32_CRYPTO
either explicitly through --enable-win32-cypto or automatically on
_WIN32 based platforms, subsequent builds broke with the following
error message:

"Can't compile NTLM support without a crypto library."

Build SMB/CIFS protocol support when SSPI is enabled.

Allow the use of the Windows Crypt API for NTLMv1 functions.

Also, fixed the outdated comments on the cookie API.

This caused a null-pointer dereference which caused a few dozen
torture tests to fail.

sws.c:2191 warning: 'rc' may be used uninitialized in this function

ftp.c:1827 warning: unused parameter 'newhost'
ftp.c:1827 warning: unused parameter 'newport'

Fixed an issue with the message size calculation where the raw bytes
from the buffer were interpreted as signed values rather than unsigned
values.

Aligned continuation character and used space as the separator
character as per other makefile files.

...and minor layout adjustment.

multi.c:2695: warning: declaration of `exp' shadows a global declaration

As it is often difficult to choose the best description for a single
feature when it spans many commits, updated the descriptions for the
recent SMB/CIFS protocol and GSS-API additions.
