[Libreoffice] Important changes in master for Windows

Hi all,

Short version:

If you are building master on a Windows platform, you should make a
full rebuild or you are going to get lots of runtime errors.

Long version:

Until now most common Win32 API calls on Windows were executed through
the uwinapi.dll layer. This lawyer was in charge of looking for ANSI
versions of the Unicode functions (using unicows.dll) on the Win9x
platforms to make the product compatible with those obsolete versions
of Windows. Thanks to the latest changes in the branch this doesn't
happen anymore and  the code calls the Win32 API directly. This should
slightly improve performance and the size of the build on the Windows
platform.

I still haven't removed the uwinapi library because sal still uses the
C99 compliant implementation of snprintf there, but the library will
be completely removed from the source code very soon.

Goodbye Win95/98/ME. You'll be missed.
