Added --event-poll option to select the method for polling events. The available methods are "select" and "epoll". "epoll" is available on Linux only. The earlier release has the compile option to choose from these methods. * configure.ac * src/RequestGroupMan.cc * src/OptionHandlerFactory.cc * src/EpollEventPoll.h * src/StreamFileAllocationEntry.cc * src/a2io.h * src/SelectEventPoll.h * src/option_processing.cc * src/prefs.h * src/EpollEventPoll.cc * src/EventPoll.h * src/SocketCore.h * src/Makefile.am * src/main.cc * src/DownloadEngine.h * src/SelectEventPoll.cc * src/DownloadEngine.cc * src/SocketCore.cc * src/DownloadEngineFactory.cc * src/Makefile.in * src/prefs.cc * src/usage_text.h
