build: use correct type for pid and similar types No thanks to 64-bit windows, with 64-bit pid_t, we have to avoid constructs like 'int pid'. Our API in libvirt-qemu cannot be changed without breaking ABI; but then again, libvirt-qemu can only be used on systems that support UNIX sockets, which rules out Windows (even if qemu could be compiled there) - so for all points on the call chain that interact with this API decision, we require a different variable name to make it clear that we audited the use for safety. Adding a syntax-check rule only solves half the battle; anywhere that uses printf on a pid_t still needs to be converted, but that will be a separate patch. * cfg.mk (sc_correct_id_types): New syntax check. * src/libvirt-qemu.c (virDomainQemuAttach): Document why we didn't use pid_t for pid, and validate for overflow. * include/libvirt/libvirt-qemu.h (virDomainQemuAttach): Tweak name for syntax check. * src/vmware/vmware_conf.c (vmwareExtractPid): Likewise. * src/driver.h (virDrvDomainQemuAttach): Likewise. * tools/virsh.c (cmdQemuAttach): Likewise. * src/remote/qemu_protocol.x (qemu_domain_attach_args): Likewise. * src/qemu_protocol-structs (qemu_domain_attach_args): Likewise. * src/util/cgroup.c (virCgroupPidCode, virCgroupKillInternal): Likewise. * src/qemu/qemu_command.c(qemuParseProcFileStrings): Likewise.
