Add OS layer ACPI mutex and threading support. - Temporary fix a bug of Intel ACPI CA core code. - Add OS layer ACPI mutex support. This can be disabled by specifying option ACPI_NO_SEMAPHORES. - Add ACPI threading support. Now that we have a dedicate taskqueue for ACPI tasks and more ACPI task threads can be created by specifying option ACPI_MAX_THREADS. - Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given caller's buffer unless AE_BUFFER_OVERFLOW occurs. Also CM battery's evaluations were changed to use acpi_EvaluateIntoBuffer(). - Add new utility function acpi_ConvertBufferToInteger(). - Add simple locking for CM battery and temperature updating. - Fix a minor problem on EC locking. - Make the thermal zone polling rate to be changeable. - Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case, entering Debugger is easier to investigate the problem rather than panic.

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.

Turn off semaphores. Nobody else implements them, and there is lots of AML out there which does totally absurd things with them, meaning that if we try to do the right thing we are guaranteed to fail.
