Subject: [PATCH] [ticket/16141] plupload chunk_size when 'unlimited' is
 involved.

Change get_chunk_size() calculation to correctly calculate limits without
letting a zero "unlimited" value always win.  Also ensure get_chunk_size()
can only return zero if all of the limits were in fact set to unlimited.
