Fix "malloc/calloc return values need explicit casts" C++ errors

There are a number of places in pixman code which are using
functions malloc/calloc/pixman_malloc_ab/pixman_malloc_abc:

pixman-access.c:    argb8_pixels = pixman_malloc_ab (width, sizeof(uint32_t));
pixman-bits-image.c:	if ((alpha = malloc (width * sizeof (uint32_t))))
pixman-bits-image.c:	if ((alpha = malloc (width * sizeof (argb_t))))
pixman-bits-image.c:	return malloc (buf_size);
pixman.c:        boxes = pixman_malloc_ab (sizeof (pixman_box32_t), n_rects);
pixman-filter.c:    p = params = malloc (*width * n_phases * sizeof (pixman_fixed_t));
pixman-filter.c:    params = malloc (*n_values * sizeof (pixman_fixed_t));
pixman-general.c:	scanline_buffer = pixman_malloc_abc (width, 3, Bpp);
pixman-glyph.c:    if (!(cache = malloc (sizeof *cache)))
pixman-glyph.c:    if (!(glyph = malloc (sizeof *glyph)))
pixman-image.c:	pixman_malloc_ab (n_stops + 2, sizeof (pixman_gradient_stop_t));
pixman-image.c:    pixman_image_t *image = malloc (sizeof (pixman_image_t));
pixman-image.c:	common->transform = malloc (sizeof (pixman_transform_t));
pixman-image.c:	new_params = pixman_malloc_ab (n_params, sizeof (pixman_fixed_t));
pixman-implementation.c:    if ((imp = malloc (sizeof (pixman_implementation_t))))
pixman-region.c:    return malloc (sz);
pixman-region.c:                rit = malloc (data_size);
pixman-trap.c:    traps = pixman_malloc_ab (n_tris, 2 * sizeof (pixman_trapezoid_t));
pixman-utils.c:    return malloc (a * b);
pixman-utils.c:	return malloc (a * b * c);
pixman-utils.c:    boxes16 = pixman_malloc_ab (n_boxes, sizeof (pixman_box16_t));
pixman-utils.c:	boxes32 = pixman_malloc_ab (n_boxes, sizeof (pixman_box32_t));
pixman-bits-image.c:	return calloc (buf_size, 1);
pixman-compiler.h:        type *value = calloc (1, sizeof (type));
pixman-compiler.h:	type *value = calloc (1, sizeof (type));

Unfortunately they fail to compile in C++ mode because the compiler wants
explicit type casts for the returned pointers:

This patch tries to solve the problem in a less invasive way by
adding some compatibility wrappers which allow compiling such
C code without modifications.
