* fhandler.h (fhandler_base): Change fstat_helper prototype

Browse Source 
to take file size and inode number as 64 bit values.
	* fhandler_disk_file.cc (FS_IS_SAMBA): Move to path.cc
	(FS_IS_SAMBA_WITH_QUOTA): Ditto.
	(path_conv::hasgood_inode): Delete.
	(path_conv::is_samba): Delete.
	(path_conv::isgood_inode): Centralized function to recognize
	a good inode number.
	(fhandler_base::fstat_by_handle): Constify fvi_size and fai_size.
	Accomodate argument change in fstat_helper.
	(fhandler_base::fstat_by_name): Ditto.
	(fhandler_base::fstat_helper): Accomodate argument change.  Call
	path_conv::isgood_inode to recognize good inodes.
	(fhandler_disk_file::opendir): Explain Samba weirdness here.
	Call path_conv::fs_is_samba instead of path_conv::is_samba.
	(fhandler_disk_file::readdir): Add STATUS_INVALID_INFO_CLASS
	as valid return code from NtQueryDirectoryFile to indicate that
	FileIdBothDirectoryInformation is not supported.
	Call path_conv::isgood_inode to recognize good inodes.
	* ntdll.h (STATUS_INVALID_INFO_CLASS): Define.
	* path.cc (fs_info::update): Rework file system recognition
	and set appropriate flags.
	* path.h (struct fs_info): Add is_ntfs, is_samba and is_nfs flags.
	Constify pure read accessors.
