When auto-dumping a domain on crash events, or autostarting a domain with managed save state, let the user configure whether to imply the bypass cache flag. * src/qemu/qemu.conf (auto_dump_bypass_cache, auto_start_bypass_cache): Document new variables. * src/qemu/libvirtd_qemu.aug (vnc_entry): Let augeas parse them. * src/qemu/qemu_conf.h (qemud_driver): Store new preferences. * src/qemu/qemu_conf.c (qemudLoadDriverConfig): Parse them. * src/qemu/qemu_driver.c (processWatchdogEvent, qemuAutostartDomain): Honor them.
