Fix --without-x build and pacify --enable-gcc-warnings.

Problems reported in Bug#18122 and Bug#18124.
* frame.c (get_frame_param): Define even if !HAVE_WINDOW_SYSTEM.
(frame_windows_min_size): Now static.
* frame.h (FRAME_HAS_HORIZONTAL_SCROLL_BARS) [!HAVE_WINDOW_SYSTEM]:
Define as no-op.
(adjust_frame_size): Always declare prototype.
