9e057c0b09 vga: Start cutting out non-32bpp conversion support
Nowadays, we either share a surface with the host, or we create
a 32bpp ARGB console surface.

So we only need to draw/convert to 32bpp, enabling us to remove
all but one instance of vga_template.h inclusion (to be further
cleaned up), rgb_to_pixel_* etc...

blitter, stippler and hardware cursor.

* Solaris and NetBSD 6.x use all the hardware acceleration features

30f1e661b6 console: stop using PixelFormat
With this patch the qemu console core stops using PixelFormat and pixman
format codes side-by-side, pixman format code is the primary way to
specify the DisplaySurface format:

 * DisplaySurface stops carrying a PixelFormat field.
 * qemu_create_displaysurface_from() expects a pixman format now.

Functions to convert PixelFormat to pixman_format_code_t (and back)
exist for those who still use PixelFormat.   As PixelFormat allows
easy access to masks and shifts it will probably continue to exist.

c1b886c45d vbe: rework sanity checks
Plug a bunch of holes in the bochs dispi interface parameter checking.
Add a function doing verification on all registers.  Call that
unconditionally on every register write.  That way we should catch
everything, even changing one register affecting the valid range of
another register.

Some of the holes have been added by commit
e9c6149f6a.  Before that commit the
maximum possible framebuffer (VBE_DISPI_MAX_XRES * VBE_DISPI_MAX_YRES *
32 bpp) has been smaller than the qemu vga memory (8MB) and the checking
for VBE_DISPI_MAX_XRES + VBE_DISPI_MAX_YRES + VBE_DISPI_MAX_BPP was ok.

Some of the holes have been there forever, such as
VBE_DISPI_INDEX_X_OFFSET and VBE_DISPI_INDEX_Y_OFFSET register writes
lacking any verification.

Security impact:

(1) Guest can make the ui (gtk/vnc/...) use memory rages outside the vga
frame buffer as source  ->  host memory leak.  Memory isn't leaked to
the guest but to the vnc client though.

(2) Qemu will segfault in case the memory range happens to include
unmapped areas  ->  Guest can DoS itself.

The guest can not modify host memory, so I don't think this can be used
by the guest to escape.

54a85d4624 vbe: make bochs dispi interface return the correct memory size with qxl
VgaState->vram_size is the size of the pci bar.  In case of qxl not the
whole pci bar can be used as vga framebuffer.  Add a new variable
vbe_size to handle that case.  By default (if unset) it equals
vram_size, but qxl can set vbe_size to something else.

This makes sure VBE_DISPI_INDEX_VIDEO_MEMORY_64K returns correct results
and sanity checks are done with the correct size too.

d16136d22a cirrus: Fix host CPU blits
Commit b2eb849d4b
"CVE-2007-1320 - Cirrus LGD-54XX "bitblt" heap overflow" broke
cpu to video blits.

When the ROP function is called from cirrus_bitblt_cputovideo_next(),
we pass 0 for the pitch but only operate on one line at a time. The
added test was tripping because after the initial substraction, the
pitch becomes negative. Make the test only trip when the height is
larger than one (ie. the pitch is actually used).

This fixes HW cursor support in Windows NT4.0 (which otherwise was
a white rectangle) and general display of icons in that OS when using
8bpp mode.

Change all the combinations to:

The case statements in the CG3 read and write register routines have a maximum
value of CG3_REG_SIZE, so if a value were written to this offset then it
would overflow the register array.

Currently this cannot be exploited since the MemoryRegion restricts accesses

future review and/or static analysis.

0983979b3a hw: use ld_p/st_p instead of ld_raw/st_raw
The ld_raw and st_raw definitions are only needed in code that
must compile for both user-mode and softmmu emulation.  Device
models can use the equivalent ld_p/st_p which are simple
pointer accessors.

fc37b7a0b0 hw/display/pxa2xx_lcd: Fix 16bpp+alpha and 18bpp+alpha palette formats
The pxa2xx palette entry "16bpp plus transparency" format is
xxxxxxxTRRRRR000GGGGGG00BBBBB000, and "18bpp plus transparency" is
xxxxxxxTRRRRRR00GGGGGG00BBBBBB00.

Correct errors in the code for reading these and converting
them to the internal format. In particular, the buggy code
was attempting to mask out bit 24 of a uint16_t, which
Coverity spotted as an error.

After previous Peter patch, they are redundant.  This way we don't
assign them except when needed.  Once there, there were lots of case
where the ".fields" indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

ead7a57df3 ssd0323: fix buffer overun on invalid state load
CVE-2013-4538

s->cmd_len used as index in ssd0323_transfer() to store 32-bit field.
Possible this field might then be supplied by guest to overwrite a
return addr somewhere. Same for row/col fields, which are indicies into
framebuffer array.

To fix validate after load.

Additionally, validate that the row/col_start/end are within bounds;
otherwise the guest can provoke an overrun by either setting the _end
field so large that the row++ increments just walk off the end of the
array, or by setting the _start value to something bogus and then
letting the "we hit end of row" logic reset row to row_start.

For completeness, validate mode as well.

848696bf35 PortioList: Store PortioList in device state
PortioList is an abstraction used for construction of MemoryRegionPortioList
from MemoryRegionPortio. It can be used later to unmap created memory regions.
It also requires proper cleanup because some of the memory inside is allocated
dynamically.

By moving PortioList ot device state we make it possible to cleanup later and
avoid leaking memory.

This change spans several target platforms.  The following testcases cover all
changed lines:
  qemu-system-ppc -M prep
  qemu-system-i386 -vga qxl
  qemu-system-i386 -M isapc -soundhw adlib -device ib700,id=watchdog0,bus=isa.0
