[Qemu-devel] [PATCH 2/2] qemu-ga: use state dir from CONFIG_QEMU_LOCALSTATEDIR

[Luiz Capitulino <lcapitulino@redhat.com>]

Has the side effect of changing the default directory used to
save the freeze status file from /tmp to ${prefix}/var/run.

This is a beneficial change for two reasons:

  1. FHS states that programs must not assume that files in /tmp will
     still exist between invocations of the program. This defeats
	 the purpose of the freeze status file

  2. FHS dictates that /var/run must be cleaned on boot, this
     ensures that a stale freeze status file will be removed on boot
