[w3m-dev 04096] w3m-img gtk2

* acinclude.m4 (AC_W3M_IMAGE): add USE_GTK2
	add --with-imagelib=gtk2
* aclocal.m4 config.guess config.sub configure: regen
* config.h.in: add USE_GTK2
* w3mimg/fb/fb_gdkpixbuf.c: support USE_GTK2
* w3mimg/fb/fb_img.h: add fb_image_init()
* w3mimg/fb/fb_imlib2.h: fb_image_init() stub
* w3mimg/fb/fb_w3mimg.c: call fb_image_init()
* w3mimg/x11/x11_w3mimg.c: support USE_GTK2
