Updated the makefiles and Visual Studio project files to support moving
the authentication code to the new lib/vauth directory that was started
in commit 0d04e859e1.
Visual Studio 2005 and above defaults to disabling the startup banner
for the Compiler, Linker and MIDL tools (with /NOLOGO). As such there
is no need to explicitly set the SuppressStartupBanner directive, as
this is a leftover from the VC7 and VC7.1 projects being upgraded to
VC8 and above.
Defined the DEBUGBUILD pre-processor variable to allow extra logging,
which is particularly useful in debug builds, as we use this and Visual
Studio typically uses _DEBUG.
We could define DEBUBBUILD, in curl_setup.h, when _MSC_VER and _DEBUG is
defined but that would also affect the makefile based builds which we
probably don't want to do.
Removed the WIN64 pre-processor definition from the libcurl project
files as:
* WIN64 is not used in our source code
* The curl projects files don't define it
* It isn't required by or used in the platform SDK
* For backwards compatability curl_setup.h defines WIN32
* The compiler automatically defines _WIN64 for x64 builds
Historically Visual Studio projects have defined WIN32, in addition to
the compiler defined _WIN32 definition, and I had incorrectly changed
that to WIN64 for the x64 libcurl builds but not in the curl projects.
As such, it is questionable whether this should be defined or not. For
more information see the following cache of a discussion that took
place on the microsoft.public.vc.mfc newsgroup:

As with commit 11397eb6dd, use $(TargetDir) and $(TargetName) for the
Import Library output rather than $(OutDir)\$(ProjectName)d.lib and
$(OutDir)\$(ProjectName).lib.
Added a more thorough version of the VC8 project files that exist in
the "vs" folder with the intention to add support for other versions of
Visual Studio. These files support side-by-side compilation, 32-bit and
64-bit builds as well as support for some of the third-party libraries
curl uses.
