lvresize: Allow approximation with +%FREE.

Browse Source 
Make lvresize -l+%FREE support approximate allocation.

Move existing "Reducing/Extending' message to verbose level
and change it to say 'up to' if approximate allocation is being used.

Replace it with a new message that gives the actual old and new size or
says 'unchanged'.
