Brian Behlendorf 3b6425cb5b Fix atomic_sub_64() i386 assembly implementation 
The atomic_sub_64() should use sbbl instead of adcl.  In user
space these atomics are used for statistics tracking and aren't
critical which explain how this was overlooked.  The kernel
space implementation of these atomics are layered on the
architecture specific implementations provided by the kernel.

Etienne Dechamps 142e6dd100 Add atomic_sub_* functions to libspl. 
Both the SPL and the ZFS libspl export most of the atomic_* functions,
except atomic_sub_* functions which are only exported by the SPL, not by
libspl. This patch remedies that by implementing atomic_sub_* functions
in libspl.
