Add async support for tomcat8

[GoogleCodeExporter]

What steps will reproduce the problem?

1.On adding memcached session manager in tomcat8 or 7, long polling stopped 
working. Without memcached it works perfectly fine.

2.I am getting following errors in tomcat logs:
java.lang.IllegalStateException: Not supported.

What version of the product are you using? On what operating system?
memcached-session-manager-1.8.1 on ubuntu, this issue is also coming on windows 
machine

Please provide any additional information below.
I am using atmosphere framework for long-polling and websockets. websockets 
works fine, but long polling fails.

Async should be basically supported, at least with reading from the session, 
see issue #75 and this commit:

Have you tried using tomcat7? Perhaps this is missing for tomcat8.

Cheers,
Martin
