John Baldwin b36cfff75d Add a simple API to manage scatter/gather lists of phyiscal addresses. 
Each list describes a logical memory object that is backed by one or more
physical address ranges.  To minimize locking, the sglist objects
themselves are immutable once they are shared.

These objects may be used in the future to facilitate I/O requests using
physically-addressed buffers.  For the immediate future I plan to use them
to implement a new type of VM object and pager.
