Re: [libvirt] [PATCH] hash: add common utility functions

I almost wrote a hash value free function that just called VIR_FREE, then realized I couldn't be the first person to do that. Sure enough, it was worth factoring into a common helper routine. Furthermore, in a few places we were passing raw free() as the cleanup function; whereas going through VIR_FREE() ensures that any (temporary) tracing or other memory stress testing that we add to viralloc.c will not be bypassed. * src/util/virhash.h (virHashValueFree): New function. * src/util/virhash.c (virHashValueFree): Implement it. * src/util/virobject.h (virObjectFreeHashData): New function. * src/libvirt_private.syms (virhash.h, virobject.h): Export them. * src/nwfilter/nwfilter_learnipaddr.c (virNWFilterLearnInit): Use common function. * src/qemu/qemu_capabilities.c (virQEMUCapsCacheNew): Likewise. * src/qemu/qemu_command.c (qemuDomainCCWAddressSetCreate): Likewise. * src/qemu/qemu_monitor.c (qemuMonitorGetBlockInfo): Likewise. * src/qemu/qemu_process.c (qemuProcessWaitForMonitor): Likewise. * src/util/virclosecallbacks.c (virCloseCallbacksNew): Likewise. * src/util/virkeyfile.c (virKeyFileParseGroup): Likewise. * tests/qemumonitorjsontest.c (testQemuMonitorJSONqemuMonitorJSONGetBlockInfo): Likewise.
