* autoload.cc (GetDiskFreeSpaceEx): Add.

Browse Source 
* syscalls.cc (statfs): Call full_path.root_dir() instead of
	rootdir(full_path). Use GetDiskFreeSpaceEx when available and
	report space available in addition to free space.
	* fhandler_disk_file.cc (fhandler_disk_file::fstat_by_name):
	Do not call FindFirstFile for disk root directories.
