--- (vhost-user-gpu) g->dmabuf[m->scanout_id] needs to be set to NULL

All that the registration does is record the existence of the backend

Jazz Jackrabbit has a very unusual VGA setup, where it uses odd/even mode
with 256-color graphics. Probably, it wants to use fast VRAM-to-VRAM
copies without having to store 4 copies of the sprites as needed in mode
X, one for each mod-4 alignment; odd/even mode simplifies the code a
lot if it's okay to place on a 160-pixels horizontal grid.
At the same time, because it wants to use double buffering (a la "mode X")
it uses byte mode, not word mode as is the case in text modes. In order
to implement the combination of odd/even mode (plane number comes from
bit 0 of the address) and byte mode (use all bytes of VRAM, whereas word
mode only uses bytes 0, 2, 4,... on each of the four planes), we need
to separate the effect on the plane number from the effect on the address.
Implementing the modes properly is a mess in QEMU, because it would
change the layout of VRAM and break migration. As an approximation,
shift right when the CPU accesses memory instead of shifting left when
the CRT controller reads it. A hack is needed in order to write font data
properly (see comment in the code), but it works well enough for the game.
Because doubleword and chain4 modes are now independent, chain4 does not
assert anymore that the address is in range. Instead it just returns
all ones and discards writes, like other modes.

Jazz Jackrabbit uses odd/even mode with 256-color graphics. This is
probably so that it can do very fast blitting with a decent resolution
(two pixels, compared to four pixels for "regular" mode X).
Accesses still use all planes (reads go to the latches and the game uses
read mode 1 so that the CPU always gets 0xFF; writes use the plane mask
register because the game sets bit 2 of the sequencer's memory mode
register). For this to work, QEMU needs to use the code for latched
memory accesses in odd/even mode. The only difference between odd/even
mode and "regular" planar mode is how the plane is computed in read mode
0, and how the planes are masked if the aforementioned bit 2 is reset.
It is almost enough to fix the game. You also need to honor byte/word
mode selection, which is done in the next patch.

This implements smooth scrolling, as used for example by Commander Keen
and Second Reality.
Unfortunately, this is not enough to avoid tearing in Commander Keen,
because sometimes the wrong start address is used for a frame.
On real EGA, the panning register is sampled on every line, while
the display start is latched for the next frame at the start of the
vertical retrace. On real VGA, the panning register is also latched,
but at the end of the vertical retrace. It looks like Keen exploits
this by only waiting for horizontal retrace when setting the display
start, but implementing it breaks the 256-color Keen games...
