Each of the graphical frontends #include a .c file, for keymap code
resulting in duplicated definitions & duplicated compiled code. A
couple of small changes allowed this to be sanitized, so instead of
doing a #include "keymaps.c", duplicating all code, we can have a
shared keymaps.h file, and only compile code once. This allows the
next patch to move the VncState struct out into a header file without
causing clashing definitions.
