Bosko Milekic 9ed346bab0 Change and clean the mutex lock interface. 
mtx_enter(lock, type) becomes:

mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks)
mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized)

similarily, for releasing a lock, we now have:

mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN.
We change the caller interface for the two different types of locks
because the semantics are entirely different for each case, and this
makes it explicitly clear and, at the same time, it rids us of the
extra `type' argument.

The enter->lock and exit->unlock change has been made with the idea
that we're "locking data" and not "entering locked code" in mind.

Further, remove all additional "flags" previously passed to the
lock acquire/release routines with the exception of two:

MTX_QUIET and MTX_NOSWITCH

The functionality of these flags is preserved and they can be passed
to the lock/unlock routines by calling the corresponding wrappers:

mtx_{lock, unlock}_flags(lock, flag(s)) and
mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN
locks, respectively.

Re-inline some lock acq/rel code; in the sleep lock case, we only
inline the _obtain_lock()s in order to ensure that the inlined code
fits into a cache line. In the spin lock case, we inline recursion and
actually only perform a function call if we need to spin. This change
has been made with the idea that we generally tend to avoid spin locks
and that also the spin locks that we do have and are heavily used
(i.e. sched_lock) do recurse, and therefore in an effort to reduce
function call overhead for some architectures (such as alpha), we
inline recursion for this case.

Create a new malloc type for the witness code and retire from using
the M_DEV type. The new type is called M_WITNESS and is only declared
if WITNESS is enabled.

Begin cleaning up some machdep/mutex.h code - specifically updated the
"optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN
and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently
need those.

Finally, caught up to the interface changes in all sys code.

* Compute offset of port-specific register. Since there are two

* DMA queues, two sets of FIFO control registers, etc...). Normally,
* the block for port 0 is at offset 0x0 and the block for port 1 is
* at offset 0x80 (i.e. the next page over). However for the transmit
* BMUs and RAMbuffers, there are two blocks for each port: one for
* the sync transmit queue and one for the async queue (which we don't
* use). However instead of ordering them like this:
* TX sync 1 / TX sync 2 / TX async 1 / TX async 2
* SysKonnect has instead ordered them like this:
* TX sync 1 / TX async 1 / TX sync 2 / TX async 2
* This means that when referencing the TX BMU and RAMbuffer registers,
* we have to double the block offset (0x80 * 2) in order to reach the
* second queue. This prevents us from using the same formula
* (sk_port * 0x80) to compute the offsets for all of the port-specific
* blocks: we need an extra offset for the BMU and RAMbuffer registers.
* The simplest thing is to provide an extra argument to these macros:
* the 'skip' parameter. The 'skip' value is the number of extra pages
* for skip when computing the port0/port1 offsets. For most registers,
* the skip value is 0; for the BMU and RAMbuffer registers, it's 1.
