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.

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.

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.

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)

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.

Add support for FCVT between half, single and double precision.

This patch adds support for those instructions in the "Floating-point
data-processing (1 source)" group which are simple 32-bit-to-32-bit
or 64-bit-to-64-bit operations (ie everything except FCVT between
single/double/half precision).
We put the new round-to-int helpers in helper.c because they will
also be used by the new ARMv8 A32/T32 rounding instructions.

Add support for the AArch64 floating-point <-> integer conversion
instructions to disas_fpintconv. In the process we can rearrange
and simplify the detection of unallocated encodings a little.
We also correct a typo in the instruction encoding diagram for this
instruction group: bit 21 is 1, not 0.

This patch adds emulation for the instruction group labeled
"Floating-point <-> fixed-point conversions" in the ARM ARM.
Namely this includes the instructions SCVTF, UCVTF, FCVTZS, FCVTZU
(scalar, fixed-point).

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.

The VFP conversion helpers for A32 round to zero as this is the only
rounding mode supported. Rename these helpers to make it clear that
they round to zero and are not suitable for use in the AArch64 code.
