5c8b0f2cc7 can_emu: Delete macros for non-existing typedef
CanBusClass doesn't exist.  This will break when we automatically
convert the code to use OBJECT_DEFINE_TYPE().  Delete the macros
that reference the non-existing typedef.

it errors out with:
 -numa hmat-cache,node-id=0,size=16K,level=2,associativity=direct,policy=write-back,line=5:
        Invalid size=16384, the size of level=2 should be less than the size(8192) of level=1

which doesn't look right as one would expect that L1 < L2 < L3 ...
Fix it by sawpping relevant size checks.

2f8cd51547 hw/display/artist: Fix invalidation of lines near screen border
If parts of the invalidated screen lines are outside of the VRAM buffer,
the code skips the whole invalidate. This is incorrect when only parts
of the buffer are invisble - which is the case when the mouse cursor is
located near the screen border.

Commit 5d971f9e67 ("memory: Revert "memory: accept mismatching sizes
in memory_region_access_valid") broke the artist driver in a way that
the dtwm window manager on HP-UX rendered wrong.

a501bfc917 hw/display/artist: Prevent out of VRAM buffer accesses
Simplify various bounds checks by changing parameters like row and column
numbers to become unsigned instead of signed.
With that we can check if the calculated offset is bigger than the size of the
VRAM region and bail out if not.

84a7b7741a hw/display/artist: Refactor artist_rop8() to avoid buffer over-run
Invalid I/O writes can craft an offset out of the vram_buffer range.
Instead of passing an unsafe pointer to artist_rop8(), pass the vram_buffer and
the offset. We can now check if the offset is in range before accessing it.

We avoid:

NetBSD initializes the LASI IMR value with 0xffffffff to disable all LASI
interrupts. This triggered an assert() and stopped the emulation.  By replacing
the check with a warning in the guest log we now allow NetBSD to boot again.
