a076a3dcbf hw/display: fix tab indentation
The TABs should be replaced with spaces, to make sure that we have a
consistent coding style with an indentation of 4 spaces everywhere.

e03b56863d Replace config-time define HOST_WORDS_BIGENDIAN
Replace a config-time define with a compile time condition
define (compatible with clang and gcc) that must be declared prior to
its usage. This avoids having a global configure time define, but also
prevents from bad usage, if the config header wasn't included before.

This can help to make some code independent from qemu too.

gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

b21e238037 Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).

Patch created mechanically with:

    $ spatch --in-place --sp-file scripts/coccinelle/use-g_new-etc.cocci \

d645427057 Include migration/vmstate.h less
In my "build everything" tree, changing migration/vmstate.h triggers a
recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

hw/hw.h supposedly includes it for convenience.  Several other headers
include it just to get VMStateDescription.  The previous commit made
that unnecessary.

Include migration/vmstate.h only where it's still needed.  Touching it
now recompiles only some 1600 objects.

58f6d82fc4 arm: explicitly mark device loads as little-endian
Behaviour of emulated devices should not depend on the endianness
of the CPU, so avoid using the endian-dependent load and store
functions in the PXA2xx and OMAP display devices. These devices
are little endian when they do DMA access.

(Since ARM softmmu is always compiled as little endian, this means
that the endian-dependent load and store functions are always little
endian, so this commit makes no functionally visible change.)

c1076c3e13 framebuffer: set DIRTY_MEMORY_VGA on RAM that is used for the framebuffer
The MemoryRegionSection contains enough information to access the
RAM region underlying the framebuffer, and can be cached inside the
display device.

By doing this, the new framebuffer_update_memory_section function can
enable dirty memory logging on the relevant RAM region.  The function
must be called whenever the stride or base of the framebuffer changes;
a simple way to cover these cases is to call it on every full frame
invalidation, which is a rare case.

framebuffer_update_display now works entirely on a MemoryRegionSection,
without going through cpu_physical_memory_map/unmap.

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.

8f1e884b38 savevm: Remove all the unneeded version_minimum_id_old (arm)
After commit 767adce2d, they are redundant.  This way we don't assign them
except when needed.  Once there, there were lots of cases where the ".fields"
indentation was wrong:

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

Change all the combinations to:

     .fields = (VMStateField[]){

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

2c62f08ddb console: simplify screendump
Screendumps are alot simpler as we can update non-active
QemuConsoles now.  So we only need to update the QemuConsole
we want write out, then dump the DisplaySurface content into
a ppm file.  Done.

No console switching needed.  No special support code in the
gfx card emulation needed.  Zap it all.  Also move ppm_save
out of the vga code and next to the qmp_screendump function.

For now screen dumping is limited to console #0 (like it used
to be), even though it is dead simple to extend it to other
consoles.  I wanna finish the console cleanup before setting
new qapi interfaces into stone.
