As these files don't need to contain references to the source files,
although typically do, added basic files which only include three
filters and don't require the project file generator to be modified.
These files allow the source code to be viewed in the Solution Explorer
in versions of Visual Studio from 2010 onwards in the same manner as
previous versions did rather than one large view of files.
Advise that WinSSL in versions <= XP will not be able to connect to
servers that no longer support the legacy handshakes and algorithms used
by those versions, and to use an alternate backend like OpenSSL instead.
Bug: https://github.com/bagder/curl/issues/253
Reported-by: zenden2k <zenden2k@gmail.com>
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.
