[PATCH 1/8] log error if virConnectCacheOnceInit() fails

This may be pointless, but I noticed it and it was bugging me. virGetConnectNetwork() calls virGetConnectGeneric(), which calls virConnecCacheInitialize(), which is actually a call (only once) to virConnectCacheOnceInit() which calls virThreadLocalInit() several times, which calls pthread_key_create() If pthread_key_create() fails, it (of course) doesn't log an error (because it's not a part of libvirt), nor does any other function on the call chain all the way up to virGetConnectNetwork(). But none of the callers of virGetConnectNetwork() log an error either, so it is possible that an API could fail due to virGetConnectNetwork() failing, but would only log "an error was encountered, but the cause is unknown. Deal with it." (paraphrasing). In all likelyhood, virConnectCacheOnceInit() is going to be called at some earlier time, and almost certainly pthread_key_create() will never fail (and if it does, the user will have *much* bigger problems than an obtuse error message from libvirt). So I don't know if there's any value at all in pushing this. Just throwing it out there...
