* cfg.mk (sc_prohibit_close): New syntax-check rule.
* src/util/pci.c (pciWaitForDeviceCleanup): Fix violation.
* .x-sc_prohibit_close: New exceptions.
* Makefile.am (EXTRA_DIST): Distribute new file.

As promised, here's my followup to Stefan's recent close() cleanups,
which will help us avoid further regressions.
