Windows: Use a customized struct stat that also has the st_blocks member.
Windows's struct stat does not have a st_blocks member. Since we already have our own stat/lstat/fstat implementations, we can just as well use a customized struct stat. This patch introduces just that, and also fills in the st_blocks member. On the other hand, we don't provide members that are never used. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at>
