kernel - Refactor buffer cache code in preparation for vm_page repurposing
* Keep buffer_map but no longer use vm_map_findspace/vm_map_delete to manage
buffer sizes. Instead, reserve MAXBSIZE of unallocated KVM for each
buffer.
* Refactor the buffer cache management code. bufspace exhaustion now has
hysteresis, bufcount works just about the same.
* Start work on the repurposing code (currently disabled).
