Let each platform typedef the new __cpu_simple_lock_t, which should
...
be the most efficient type used for the atomic operations in the
simplelock structure, and should also be __volatile.

Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file
...
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.
These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

provide an __ELF__ version of _C_FUNC and _C_LABEL, convert the assembly

#defines in asm.h to use them, and convert code which needs to use C labels
to use _C_LABEL as well. (I can't see any reason why the label vs. function
differentiation shouldn't be GC'd; i only added uses of _C_LABEL.) This
should help if this port is converted to use ELF, and was checked by
compiling all kernels in arm32/conf (with some driver removals and some
MI header fixups re: common blocks) with an arm-linux ELF toolchain.

Change the semantics of splsoftclock() to be like other spl*() functions,
...
that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.
This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).
XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.
