sched/debug: Add a new sched_trace_*() helper functions
The new functions allow modules to access internal data structures of
unexported struct cfs_rq and struct rq to extract important information
from the tracepoints to be introduced in later patches.
While at it fix alphabetical order of struct declarations in sched.h
