Move the dirty queues inside the per-domain structure.  This resolves a bug
where we had not hit global dirty limits but a single queue was starved
for space by dirty buffers.  A single buf_daemon is maintained for now.

Add a bd_speedup() when we are low on bufspace.  This can happen due to SUJ
keeping many bufs locked until a cg block is written.  Document this with
a comment.

Fix sysctls to work with per-domain variables.  Add more ddb debugging.
