Simplify completer handling by isolating readline-specific logic more....

Simplify completer handling by isolating readline-specific logic more. Also, I removed a hack we were using of storing the completer globally inside sys. This was used for the rare case of embedding ipython-inside-ipython, something which is more of a party trick. If we ever want to support that well, we can write a cleaner solution than polluting sys with 'ipcompleter'. But for now, I'm trying to simplify our completer machinery and remove buggy and/or error-prone hacks. Note that the normal use of embedded ipython inside of user's programs isn't affected by this.

      """Utilities to enable code objects to be pickled.

      Any process that import this module will be able to pickle code objects.  This

      includes the func_code attribute of any function.  Once unpickled, new 

      functions can be built using new.function(code, globals()).  Eventually

      we need to automate all of this so that functions themselves can be pickled.
