["Benoît Canet" <benoit@irqsave.net>]

This patchset implement continous leaky bucket throttling.

It use two requests queue to enable to do silly unbalanced throttling like
block_set_io_throttle 0 0 0 0 6000 1

It use two timer to get the timer callbacks and the throttle.c code simple

   Drop Eric Reviwed by as patches have changed [Benoît]
   fix badly concatenated string [Fam]
   Add description of burst in header [Fam]
   Fix braces spacing [Fam]
   Fix qemu-options.hx bracket [Fam]
