da21e89daa Use nearest scaling for DRAW_ALPHA_BLEND since this is what win32 needs 
DrvAlphaBlend is the only current user of DRAW_ALPHA_BLEND, and its
defined to do nearest (COLORONCOLOR) scaling, not bilinear.

6664c12278 Fix up empty region checks in canvas operations 
We rely on not passing on empty rects to the drawing operations by
checking for empty regions and exiting early. However the checks
were wrongly using pixman_region32_n_rects(region) == 0, whereas
we should be using pixman_region32_not_empty().

440ac41cf1 New memory allocators that exit on OOM and handle multiplication overflow 
Every place that does a regular malloc/calloc and aborts on failure
should use spice_malloc/spice_mallo0 instead, which is leaner and cleaner.

Allocations of dynamically sized arrays can use g_malloc_n or g_new etc
which correctly handle multiplication overflow if some of the arguments
are not trusted.

e00bce8e25 Move most of the shared draw_xyz() methods from CairoCanvas to CanvasBase 
This adds a set of virtual methods for low-level operations. A subclass
can choose to implement those and let the default CanvasBase implementations
handle the highlevel stuff.

f8217d8b96 Move virtualization of canvas drawing into common/canvas_base 
Instead of having two virtualizations of the canvas we push the
virtualization into the canvas code itself. This not only avoids
the duplication of this code, it also makes the exposed API for the
canvas much smaller (in terms of exported API).

It also lets us use the virtualization to implement basic support
for operations in canvas_base which is then overridden by each canvas
implementation.

f7a77f9881 Make glz_decoder non-optional canvas_base in canvas constructors 
It can still be NULL, but we simplify the headers by always including it.
There is no practical performance difference here.

04b35fe7ff Fix colorkeying in pixman_utils.c 
We were masking out the alpha bit in the key color not int
the source pixel, so colorkeying didn't work when the high byte
was != 0. For instance in the shutdown dialog in XP.

98dde80ed3 Replace custom region implementation with pixman_region32_t 
pixman_region32_t is an efficient well tested region implementation (its
the one used in X) that we already depend on via pixman and use in
some places. No need to have a custom region implementation.

a7ceb98ea1 Add possibility to not invert bitmask in canvas_get_mask() 
This allows the pixman implementation to instead invert the (generally
smaller) region instead of duplicating the bitmap to invert it.

16780a7b81 Use pixman_image_t instead of cairo_surface_t as the generic pixman container 
This allows us to use the simpler dependency of pixman outside of the
cairo backend, and it later lets us move the cairo backend to using
pixman only.

0b0342ee7e Turn image and palette cache into c style dynamic interface 
Instead of passing a bunch of function pointer and an opaque
pointer we make a real type and add a vtable pointer to it.
This means we can simplify all the canvas constructors, etc.

79d8c5c6a4 Add pixman_image_t referencing the cairo_canvas bits

for drawing to the surface using direct pixman calls instead.
