catch messages that occur during VAP startup (before you can possibly invoke 80211debug). Support for shared debug flags where they take effect across all devices (i.e. shared flags in athdebug), and when they take effect across all VAPs (i.e. shared flags in 80211debug). Some additional debugging flags, including some in preparation for more leak detection code to be merged shortly as well as some from madwifi-dfs. git-svn-id: http://madwifi-project.org/svn/madwifi/trunk@2888 0192ed92-7a03-0410-a25b-9323aeb14dbd
