commit f1fe9671e
was supposed to make sure we use files.h
macros to avoid double close, but it didn't work.
Meanwhile, virCommand is vastly superior to system(), fork(),
and popen() (also to virExec, but we haven't completed that
conversion), so enforce that, too.
* cfg.mk (sc_prohibit_close): Fix typo that excluded close, and
add pclose.
(sc_prohibit_fork_wrappers): New rule, for fork, system, and popen.
* .x-sc_prohibit_close: More exemptions.
* .x-sc_prohibit_fork_wrappers: New file.
* Makefile.am (syntax_check_exceptions): Ship new file.
* src/datatypes.c (virReleaseConnect): Tweak comment to avoid
false positive.
* src/util/files.h (VIR_CLOSE): Likewise.
