	calling fstat_by_handle.  Always unlock node before returning.
	Use fhandler's unique id to create lf_id for BSD flock locks.
	Rely on node lock from inode_t::get.  Call del_lock_obj on removed
	locks here to allow explicit unlocking.  Delete node if no lock exists
	on the file anymore.
	(lf_setlock): Get file handle as additional parameter.  Handle the fact
	that lf_getblock now always opens the attached event object.  Reactivate
	erroneously applied patch which deactivates setting thread priority.
	Additionally handle blocking on BSD flock locks.
	(lf_clearlock): Get file handle as additional parameter.
	(lf_getlock): Close event handle opened by lf_getblock.
	(lf_getblock): Open potentially blocking event object here and check
	its signal state if it's a BSD flock lock.
	(lf_wakelock): Get file handle as additional parameter.

	* fhandler.h (get_dev): New method.
	* fhandler_disk_file.cc (fhandler_base::fstat_by_handle): Drop call to
	NtQueryVolumeInformationFile(FileFsVolumeInformation).  Just use
	get_dev() method.

	to generate fifo name.
