Plumb network vif credit-based rate limiting thorugh xenbus
and xend into xm guest config files.

A new vif parameter 'rate' is supported, with an optional time window
paremeter for specifying granularity of credit replenishment. The default
window is 50ms. For example:

 'rate=10Mb/s'  'rate=250KB/s'  'rate=1MB/s@20ms'

Is this rate in+out or out only? Also, perhaps Chris could explain for us non-kernel hackers the purpose of specifying the credit replenishment granularity and how it can be beneficial to tune it under certain circumstances?

Thank you,
Matt Ayres
