Merge minidumps from amd64 where they were originally developed.

Major differences:
 * since there is no direct map region, there is no custom uma memory
   allocator to modify to include its pages in the dumps.
 * Various data entries are reduced from 64 bit to 32 bit to match the
   native size.

dump_add_page() and dump_drop_page() are still present in case one wants to
arrange for arbitary pages to be dumped.  This is of marginal use though
because libkvm+kgdb cannot address physical memory that isn't mapped into
kvm.
