- started factoring VipsArea out into area.[hc]

see vips_bandjoin() .. ugly!

/* im_gbandjoin -- bandwise join of a set of images
*
* Copyright: 1991, N. Dessipris, modification of im_bandjoin()
*
* Author: N. Dessipris
* Written on: 17/04/1991
* Modified on :
* 16/3/94 JC
* - rewritten for partials
* - now in ANSI C
* - now works for any number of input images, except zero
* 7/10/94 JC
* - new IM_NEW()
* 16/4/07
* - fall back to im_copy() for 1 input image
* 17/1/09
* - cleanups
* - gtk-doc
* - im_bandjoin() just calls this
* - works for RAD coding too
* 27/1/10
* - formatalike inputs
* 17/5/11
* - sizealike inputs
