Rewrite virAtomic APIs using GLib's atomic ops code There are a few issues with the current virAtomic APIs - They require use of a virAtomicInt struct instead of a plain int type - Several of the methods do not implement memory barriers - The methods do not implement compiler re-ordering barriers - There is no Win32 native impl The GLib library has a nice LGPLv2+ licensed impl of atomic ops that works with GCC, Win32, or pthreads.h that addresses all these problems. The main downside to their code is that the pthreads impl uses a single global mutex, instead of a per-variable mutex. Given that it does have a Win32 impl though, we don't expect anyone to seriously use the pthread.h impl, so this downside is not significant. * .gitignore: Ignore test case * configure.ac: Check for which atomic ops impl to use * src/Makefile.am: Add viratomic.c * src/nwfilter/nwfilter_dhcpsnoop.c: Switch to new atomic ops APIs and plain int datatype * src/util/viratomic.h: inline impls of all atomic ops for GCC, Win32 and pthreads * src/util/viratomic.c: Global pthreads mutex for atomic ops * tests/viratomictest.c: Test validate to validate safety of atomic ops.

maint: check all symfiles for sorting On FreeBSD, I got a 'make check' failure: GEN check-symsorting Symbol block at ./libvirt_atomic.syms:4: viratomic.h not found * src/Makefile.am (SYM_FILES): New define. (check-symsorting): Check on all symfiles, even when not used. * src/libvirt_atomic.syms: Fix offender. 2013-02-22 23:46:25 +00:00			`# util/viratomic.h`
