Revert6a1f5f568f. Now that libvirt_iohelper takes fds by inheritance rather than by open() (commit1eb66479), there is no longer a race where the parent can unlink() a file prior to the iohelper open()ing the same file. From there, it makes more sense to have the callers both create and unlink, rather than the caller create and the stream unlink, since the latter was only needed when iohelper had to do the unlink. * src/fdstream.h (virFDStreamOpenFile, virFDStreamCreateFile): Callers are responsible for deletion. * src/fdstream.c (virFDStreamOpenFileInternal): Don't leak created file on failure. (virFDStreamOpenFile, virFDStreamCreateFile): Drop parameter. * src/lxc/lxc_driver.c (lxcDomainOpenConsole): Update callers. * src/qemu/qemu_driver.c (qemuDomainScreenshot) (qemuDomainOpenConsole): Likewise. * src/storage/storage_driver.c (storageVolumeDownload) (storageVolumeUpload): Likewise. * src/uml/uml_driver.c (umlDomainOpenConsole): Likewise. * src/vbox/vbox_tmpl.c (vboxDomainScreenshot): Likewise. * src/xen/xen_driver.c (xenUnifiedDomainOpenConsole): Likewise.
