More undeclared function fixes and add -Wimplicit-function-declaration.

If a function returns Lisp_Object it must be declared, otherwise on a 64-bit
system, it will return just 32 bits (int).

* configure.in: Use -Wimplicit-function-declaration if compiler supports it.

* src/keyboard.h (poll_for_input_1): Unconditionally declare.

* src/xterm.h (x_get_focus_frame): Declare.
