Set timeout(9) to refill the receive ring descriptors if the amount of
descriptors runs below the low watermark.

The em(4) firmware seems not to work properly with just a few descriptors in
the receive ring.  Thus, we use the low water mark as an indicator instead of
zero descriptors, which causes deadlocks.

add if_rxr_livelocked so rxr users can request backpressure themselves.

right now the rx ring moderation code makes a decision globally
that a machine is livelocked, and uses that to apply backpressure
on all the rx rings. we're moving toward having the network stack
run on multiple cpus, and fed from multiple rx rings. if_rxr_livelocked
lets a driver apply backpressure explicitely if something tells it
that whatever is consuming previous packets cannot keep up.

while here expose the current ring watermark with if_rxr_cwm.

wrap some long lines for function prototypes with .Fo, .Fa, and .Fc.

no functional change, ie, the output is the same

Remove useless quoting from .Fo and .Fn function names, to prevent
development of a cargo cult in case people look at existing files
for examples.  This achieves a consistent .Fo and .Fn quoting style
across the whole tree.

introduce the if_rxr api. it is intended to pull the rx ring accounting
out of the mbuf layer, and break the assumption that an interface will
only have a single ring per mbuf cluster size.

mpi@ is ok with moving this forward
