patch moving support to xpsp2 and later

In the end of last week we had a conversation on #qtwebkit with Jocelyn to see what options are available for fixing WebKit2 build on Windows. MSVC's InterlockedIncrement64 method is available from XPSP2. This patch moves support from 2000 to XPSP2 and later versions of Windows. Let see what is EWS' opinion about this. On my test machine it seems to be ok.

The other way is to implement the required atomicIncrement functionality in assembly for (current) older target Windows target version. This approach was in the previous patch, but it needs a copyright clarification.
