Change the way input is read

Before rp used xgrabkeyboard to read a key. Instead, the keyboard is
frozen when a top level key is read. Then when rp reads a key it first
sets the input focus to a suitable location such as key_window or
input_window, then thaws the keyboard and waits for a keypress. When a
key is pressed the keyboard is frozen again and the process repeats
until ratpoison is done reading input. At that point the keyboard is
thawed in a way that future keystrokes do not refreeze the keyboard.
