[libvirt] [PATCH v3] bye to close(), welcome to VIR_(FORCE_)CLOSE()

Now that 0.8.5 is out, here is another posting of this big cleanup patch. If there are some dubious hunks in it, please let me know and I'd rather cut them out and we fix them with in separate patches... There were some problems with Eric's suggested cfg.mk extension (showing contents of error messages with 'close' as text), so I could not add the 'sc_avoid_close' to it. I again put the diff of tree+v3 against tree+v1 to the end of the patch. I forward-ported V1 for that. V3: - reaction to Daniel's comments on V2 V2: - forgot to convert close ( occurrences (with whitespace) - following Eric's and Laine's comments Using automated replacement with sed and editing I have now replaced all occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of course. Some replacements were straight forward, others I needed to pay attention. I hope I payed attention in all the right places... Please have a look. This should have at least solved one more double-close error.
