Subject: [PATCH] clean up wxEvtHandler::m_eventsLocker weirdness: there is no
 need to allocate it dynamically (as it's always done anyhow), this removes
 the need for ClearEventLocker() and OS/2 #ifdefs

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@51027 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
