ab518eea9c mount: create loop devices with LO_FLAGS_AUTOCLEAR flag 
The "autolooped" mount (mount [-oloop] IMAGE /DIR/DIR)
always creates AUTOCLEARed loopdevs, so that umounting
drops them (and this does not require any code in the
umount userspace).
This happens since circa linux-2.6.25:
	commit 96c5865559cee0f9cbc5173f3c949f6ce3525581
	Date:    Wed Feb 6 01:36:27 2008 -0800
	Subject: Allow auto-destruction of loop devices
IOW: in this case, umount does not have to use -d
to drop the loopdev.

The explicit loop mount (mount /dev/loopN /DIR/DIR)
does not do this. In this case, umount without -d
should not drop loopdev.
Unfortunately, bbox umount currently always implies -d,
this probably needs fixing.

f560422fa0 Big cleanup in config help and description 
Redundant help texts (one which only repeats the description)
are deleted.

Descriptions and help texts are trimmed.

Some config options are moved, even across menus.

No config option _names_ are changed.

b09ab448b8 mount: for cifs, dont insert "ip=ADDR" option if user gave it explicitly 
This makes it possible to use scoped IPv6 addresses:

301fe50ca2 mount: ignore unknown mount options when remounting NFS mounts 
Don't fail on unknown nfs mount options. The kernel automatically
adds a few mount options that we don't currently handle, like:

	sec=null|sys|krb5..
	mountaddr=<ip>
	mountproto=tcp|udp
	local_lock=none|all|flock|posix

Which causes a simple mount -o remount,rw <mountpoint> to fail.

When mounting a filesystem without any additional options (data parameter
to the mount(2) syscall), pass NULL instead of an empty string like GNU
mount does. This fixes, for example mounting cgroup fs with bbox mount.
