This patch changes how preemptions of jobs without
budget work. Instead of requeuing them, they are now
only added if they are not subject to budget enforcement
or if they have non-zero budget. This allows us to process
job completions that race with preemptions.
This appears to fix a BUG in budget.c:65 reported by Giovani Gracioli.

litmus.h is accumulating too many things. Since
we already have budget.h, let's stick all budget-related
inline functions there as well.
This patch is merely cosmetic; it does not change
how budget enforcement works.

Simple logic: if a task requires precise enforcement, then program a
hr-timer to fire when the task must be descheduled. When the timer
fires, simply activate the scheduler. When we switch to a different
task, either reprogram the timer or cancel it.
