9c22687ea8 bitmap: use long as index
Move index and size fields from int to long.  We need that for
migration.  long is 64 bits on sane architectures, and 32bits should
be enough on all the 32bits architectures.

40596834c0 migration: Fix rate limit
The migration thread appears to want to allow writeout to occur at full
speed rather than being rate limited during completion of state saving,
but sets the limit to INT_MAX when xfer_limit is INT64_MAX. This causes
problems if there's more than 2GB of state left to save at this point. It
probably ought to just be INT64_MAX instead.

7d270b1c21 ui/cocoa: Draw black rectangle if we have no data yet
If our redraw method is called before we have any data from the guest,
then draw a black rectangle rather than leaving the window empty.
This mostly only matters when the guest machine has no framebuffer
device, but it is more in line with the behaviour of other QEMU UIs.

d3345a0484 ui/cocoa: Redraw at correct size when switching surface
If the surface switch involved a resize, we were doing the redraw
at the old size rather than the new, because the update of
screen.width and screen.height was being done after the setFrame
method calls which triggered a redraw. Normally this isn't very
noticeable because typically after the guest triggers the window
resize it also draws something to it, which will in turn cause
us to redraw. However, the combination of a guest which never
draws to the display and a command line setting of a screen size
larger than the default can reveal odd effects.

Move most of the handling of resizes to the top of the method,
and guard it with a check that the surface size actually changed,
to avoid unnecessary operations (including some user visible ones
like "recenter the window on the screen") if the surface is the
same size as the old one.

98db429d2c ui/cocoa: Fix code for starting QEMU via image file load dialog
Fix a number of bugs in the code for starting QEMU via the image
file load dialog:
 * use the actual argv[0] rather than "qemu": this avoids failures to
   find BIOS image files caused by not looking in the correct directory
   relative to the executable path
 * allocate a large enough argv array to NULL terminate it
 * use g_strdup(X) rather than g_strdup_printf("%s", X) or
   g_strdup_printf(X)
 * disable the printing of the simulated command line argument
   (which is presumably intended for debug only)

8895919a04 ui/cocoa: Pass command key through to guest when VM has mousegrab
The guest might want to be able to use the command key for its won
purposes (as command if it is MacOS X, or for the Windows key if
it is a PC guest, for instance). In line with other UI frontends,
pass it through if the guest has mousegrab, and only use it for UI
menu accelerators if not grabbed.

Thanks to John Arbuckle for reporting this problem, helping
us work through what the best solution would be and providing
a patch which was the initial inspiration for this one.

abe66f702c target-arm: Ignore most exceptions from scalbn when doing fixpoint conversion
The VFP fixed point conversion helpers first call float_scalbn and
then convert the result to an integer. This scalbn operation may
set floating point exception flags for:
 * overflow & inexact (if it overflows to infinity)
 * input denormal squashed to zero
 * output denormal squashed to zero
Of these, we only care about the input-denormal flag, since
the output of the whole scale-and-convert operation will be
an integer (so squashed-output-denormal and overflow don't
apply). Suppress the others by saving the pre-scalb exception
flags and only copying across a potential input-denormal flag.

8ed697e88b target-arm: Prepare VFP_CONV_FIX helpers for A64 uses
Make the VFP_CONV_FIX helpers a little more flexible in
preparation for the A64 uses. This requires two changes:
 * use the correct softfloat conversion function based on itype
   rather than always the int32 one; this is possible now that
   softfloat provides int16 versions and necessary for the
   future conversion-to-int64 A64 variants. This also allows
   us to drop the awkward 'sign' macro argument.
 * split the 'fsz' argument which currently controls both
   width of the input float type and width of the output
   integer type into two; this will allow us to specify the
   A64 64-bit-int-to-single conversion function, where the
   two widths are different.

We can also drop the (itype##_t) cast now that softfloat
guarantees that all the itype##_to_float* functions take
an integer argument of exactly the correct type.

f9288a76f1 softfloat: Add support for ties-away rounding
IEEE754-2008 specifies a new rounding mode:

"roundTiesToAway: the floating-point number nearest to the infinitely
precise result shall be delivered; if the two nearest floating-point
numbers bracketing an unrepresentable infinitely precise result are
equally near, the one with larger magnitude shall be delivered."

Implement this new mode (it is needed for ARM). The general principle
is that the required code is exactly like the ties-to-even code,
except that we do not need to do the "in case of exact tie clear LSB
to round-to-even", because the rounding operation naturally causes
the exact tie to round up in magnitude.
