Automatically find name exceptions for functions, methods and classes in Twisted.

Detail:
1. Find patterns like 'getattr(something, "state_%s" % foo)' and 'getattr(something, "state_" + foo)' and generate a list of these patterns (end with underscore).
2. modify regex that verifies function, method and class name in NameChecker, to ignore these patterns.

Currently found patterns in Twisted:
telnet_, sync_, _fromString_, auth_, perspective_, handleStatus_, Record_, _parseSVNEntries_, get_, xmlrpc_, state_, iac_, macro_, handle_, start_, _process_, ctcpReply_, parse_, dcc_, _toString_, observe_, func_, async_, spew_, soap_, _stat_, convert_, channel_, ftp_, global_, packet_, removeTrigger_, ext_, class_, opt_, do_, request_, render_, ssh_, _unjelly_, response_, agentc_, cmd_, key_, ctcpQuery_, generate_, view_, ssh_USERAUTH_PK_OK_, end_, oscar_, type_, irc_, search_, remote_, linemode_, decode_, visitNode_a_, login_, visitNode_

Invalid names remain in Twisted:
check_, dont_, esmtpState_, inotify_, inotify_, on_, packRequest_, parseRequest_, smtpState_, testAddingBadProtos_, will_, wont_, testAlreadyCalledDebug_, testAlreadyCalled_
