Log Message:
-----------
linux-gen: queue: remove extra checks
Remove unnecessary checks from critical sections of scheduled
queue enqueue and dequeue operations. Parallelism improves when
the number of instructions and (potential) cache misses decreases
when holding the lock.

linux-gen: sched: clean up local data struct
Move stash variables into a struct. Use only 16 bits for thread id,
which is enough for 64k threads.

Log Message:
-----------
linux-gen: sched: single variable for sync context status
Use single thread local variable to keep track if
a synchronization context is held and the type of the context
(atomic or ordered). Performance is improved as sync context
status is located on single (the first) cache line of
sched_local_t.

linux-gen: sched: remove queue_destroy_finalize callback
Scheduled queue dequeue function calls directly the scheduler
queue destroy callback. Sched_queue_deq() usage is simpler
when the extra round of callbacks is removed.

-----------
linux-gen: ring: change ring_deq return value
Return number of data values dequeued (0 or 1) instead of
the data value. This improves error tolerance as there's no
data value reserved to indicate empty ring. Also CPU may
speculate further before the actual data value is actually
needed.
