Replace the swap extent(9) usage by a blist data structure.
It makes uvm_swap_free() faster: extents have a cost of O(n*n) which doesn't
really scale with gigabytes of swap.
Based on initial work from mpi@
The blist implementation comes from DragonFlyBSD.
The diff adds also a ddb(4) 'show swap' command to show the blist and help
debugging, and fix some off-by-one in size printed during hibernate.
