This enables libcroco to be compiled with Visual C++ 2008/2010, along
with its test programs.  A libcroco.symbols is included to export the
symbols from the DLL that is built in the process, and the projects
for the main libcroco DLL is done in a way where their source file
listings are filled in during "make dist" as they could be changed from
time to time so to simplify maintenanace work.  Versioning stuff are
also done via autotools as far as possible also.

The .sln files have no simple way to include the LGPL 2.1+ terms without
causing trouble, so the text for them is included as follows, for
references.
