Upgrade jboss remoting to v2.2.2.SP8 (from v2.2.2.SP5)

EAP 4.2/4.3 are currently shipping with Remoting 2.2.2.SP7 and testing with 2.2.2.SP8 for the next CP releases. We could just update to 2.2.2.SP7, but I think JBREM-949 in 2.2.2.SP8 is important to JBossMessaging.

Many of the other bug reports arose in support cases: JBREM-962, JBREM-965, JBREM-981

Reported by Galder: JBREM-954, JBREM-960

Reported by Ovidiu: JBREM-972, JBREM-973
