Move all the frontend struct and methods to a seperate unit. This avoids accidentally mixing backend and frontend calls, and helps with readabilty. Make qemu_chr_replay() a macro shared by both char and char-fe. Export qemu_chr_write(), and use a macro for qemu_chr_write_all() (nb: yes, CharBackend is for char frontend :) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
