win32: use the version major libvlc number in the DLL name
This will avoid loading incompatible DLLs automatically.
Windows app can still link with libvlc.lib
and libvlc.dll.a
. These names are not versioned, they point to the versioned DLL.
Separate libvlc and libvlccore DLL files as they don't describe the same thing.
