solaris implementation volatile qualifier removal

Remove volatile qualifiers and issue memory barriers where appropriate to
prevent reordering. The solaris atomic man page says:

"The membar_consumer() function arranges for all loads issued before this point

in the code to be completed before any subsequent loads."

and

"The membar_producer() function arranges for all stores issued before this
point
in the code to reach global visibility before any stores that follow."

TODO: the other function may still need explicit memory barriers.
