- ppc fixes (s/stw/stwx/, s/lwz/lwzx) - missing early clobbers added for x86, sparc*, armv6, ppc*, alpha

- fastlock: optimizations (in general a "nicer" spin on the lock for the other cpus) and cleanups for sparc, sparc64, armv6 (nosmp for now), ppc*, mips* - fastlock: alpha: replace the cond. jump backward with a cond. jump forward and then jump backward (because a cond. jump with a negative relative offset is always predicted as taken and we want it to be predicted as not taken) - fastlock: sparc (32) smp support - lock_ops.h: introduced lock_try and lock_set_try (non-blocking lock_*_get versions, returns -1 if it failed to get the lock and 0 if it succeeds), for all the supported locking methods (fast_lock, pthread_mutex, posix_sem, sysv_sems) - updated locking doc.

- membar_write on x86_64 is by default empty (since on amd64 stores are always ordered)

- lock optimizations: use the lock specific membar only if the lock_get operation succeeded (this means don't use it while spinning) => move the membar call in get_lock or try_lock

- added atomic ops & mem. barriers support for: - arm - arm v6 (untested, but it compiles ok) - alpha (untested. but it compiles ok) - fastlock: minor fixes - Makefile.defs: support for mip64 and armv6; various minor fixes

- added mb_atomic_* ops, equivalent to membar(); atomic_*, but more optimized (e.g. on x86 most atomic ops act also as memory barriers so mb_atomic_* will be equiv. to atomic_* )

- experimental ppc locking tweaks (not tested) - ppc64 enabled (the same ppc code should work)
