Summary: The IOHandler class source file is currently around 4600 LOC. However only 200 of these lines are concerned with the actual IOHandler class and the rest are the implementations for Editline, IOHandlerConfirm and the Curses interface. All these large features also cause that the IOHandler (which is in Core) has a large set of dependencies on other parts of LLDB. This patch splits out the code for the curses interface into its own file. This way the simple IOHandler code is no longer buried in-between much larger functionalities. Next up is splitting out the other IOHandlers into their own files and then move them to more appropriate parts of LLDB.
