2014-01-13migration: Fix rate limitMatthew Garrett1-1/+1
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.

2014-01-12ui/cocoa: Draw black rectangle if we have no data yetPeter Maydell1-1/+6
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.

2014-01-12ui/cocoa: Redraw at correct size when switching surfacePeter Maydell1-7/+17
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.

2014-01-12ui/cocoa: Pass command key through to guest when VM has mousegrabPeter Maydell1-7/+18
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.
