Replace the 4k fixed sized jumbo mbuf clusters with PAGE_SIZE sized
jumbo mbuf clusters. To make the variable size clear they are named
MJUMPAGESIZE.
Having jumbo clusters with the native PAGE_SIZE is more useful than
a fixed 4k size according the device driver writers using this API.
The 9k and 16k jumbo mbuf clusters remain unchanged.
