slirp: Drop dead code
After all its years inside the qemu tree, there is no point in keeping the dead code paths of slirp. This patch is a first round of removing usually commented out code parts. More cleanups need to follow (and maybe finally a proper reindention). Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
