When gcc atomic intrinsics are not available (such as on RHEL 5

/home/dummy/l,ibvirt/src/util/viratomoic.h:404: multiple definition of

./.libs/libvirt_util.a(libvirt_util_la-viratomic.o):/home/dummy/libvirt/src/util/viratomic.h:404:
first defined here
Solve this by conditionally marking the functions static (the
condition avoids falling foul of gcc warnings about unused
static function declarations).
* src/util/viratomic.h: When not using gcc intrinsics, use static
functions to avoid linker errors on duplicate functions.

Pushing under the build-breaker rule. Tested on both RHEL 5
and modern gcc of F17.
Oh, and I just noticed my indentation is off, while preparing
this email; I'll squash in the whitespace fix before pushing.

ACK, this looks good to me.
