[w3m-dev 03929] clear image
* image.c (syncImage): added
(drawImage): rewrite using syncImage()
(clearImage): use clear image command (6)
* w3mimgdisplay.c: change protocol
2 => terminate drawing
6 => clear image
(main): '2' calls TermImage()
'6' calls ClearImage()
TermImage() when exit
(TermImage): renamed from ClearImage
(ClearImage): rewritten to call w_op->clear()
* w3mimg.h/w3mimg.h (w3mimg_op): add clear()
* w3mimg/fb/fb.c (fb_clear): added
* w3mimg/fb/fb.h (fb_clear): added
* w3mimg/fb/fb_img.c (fb_image_clear): added
* w3mimg/fb/fb_w3mimg.c (w3mfb_clear): added
(w3mimg_fbopen): initialize wop->clear
* w3mimg/x11/x11_w3mimg.c (x11_clear): added
(w3mimg_x11open): initialize wop->clear
