Subject: [RFC v5 PATCH 1/8] sched: Rename struct rt_bandwidth to
	sched_bandwidth

sched: Rename struct rt_bandwidth to sched_bandwidth

From: Dhaval Giani <dhaval@...ux.vnet.ibm.com>

Rename struct rt_bandwidth to sched_bandwidth and rename some of the
routines to generic names (s/rt_/sched_) so that they can be used
by CFS hard limits code in the subsequent patches.

No functionality change by this patch.
