	src/sys/uvm: uvm_swap.c

Log Message:
switch swap space allocation code to use blist instead of extent(9).
fix "warning: resource shortage: %d pages of swap lost".

extent(9) has some undesirable characteristics for swap allocation:
	- it involves alloc-to-free.
	- its operational cost is O(n*n) where n is number of entries.
