* autoload.cc (NtQueryVolumeInformationFile): Add.

Browse Source 
* fhandler.cc (fhandler_base::raw_write): Don't touch has_changed flag.
	* fhandler.h (enum change_state): Remove.
	(fhandler_base::status): Revert has_changed to a simple bit.
	(fhandler_base::fstat_helper): Add nAllocSize parameter.  Rename
	ftCreationTime to ftChangeTime.
	* fhandler_disk_file.cc:
	Call fstat_helper with additional
	allocation size throughout.
	(fhandler_base::fstat_by_handle): Use NT native functions to get
	full file information on NT.  Call fstat_helper with LastWriteTime
	as ctime, if ChangeTime is not available.
	(fhandler_base::fstat_by_name): Call fstat_helper with LastWriteTime
	as ctime.
	(fhandler_base::fstat_helper): Add comment. Drop special FAT
	handling since it's useless. Use nAllocSize for st_blocks if available.
	(fhandler_disk_file::touch_ctime): Only touch LastWriteTime.
	(fhandler_disk_file::fchmod): Set has_changed on 9x only.
	(fhandler_disk_file::fchown): Don't set has_changed.
