Change API: spinlock_t -> raw_spinlock_t

Adapt to new schema for spinlock:
(tglx 20091217)
spinlock - the weakest one, which might sleep in RT
raw_spinlock - spinlock which always spins even on RT
arch_spinlock - the hardware level architecture dependent implementation

----

Planning for future porting on PreemptRT, probably all of the
spinlock changed in this patch should true spinning lock (raw_spinlock).

There are a couple of spinlock that the kernel still defines as
spinlock_t (therefore no changes reported in this commit) that might cause
problems to us:
- wait_queue_t lock is defined as spinlock_t; it is used in:
  * fmlp.c -- sem->wait.lock
  * sync.c -- ts_release.wait.lock
- rwlock_t used in fifo implementation in sched_trace.c
  * this need probably to be changed to something always spinning in RT
    at the expense of increased locking time.
