[spp] [PATCH 1/5] Add SO_REUSEADDR option

[ogawa.yasufumi at lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi at lab.ntt.co.jp>

spp.py cannot be launched if it is terminated for unexpected error
and try to restart because of 'port is already used'.
This patch is for avoiding the situation by releasing port
immediately when spp.py is treminated.
