Do not even care to create WithoutFreeSpace image, it is obsolete.
Always create WithouFreSpacExt one.

The code also does not spend a lot of efforts to fill cylinders and
heads fields, they are not used actually in a real life neither in
QEMU nor in Parallels products.

Switch the .bdrv_read method implementation from using bdrv_pread() to
bdrv_read() on the underlying file, since the latter is subject to i/o

Besides, since bdrv_read() operates in sectors rather than bytes, adjust

Put the number of serial ports into a local variable in
multi_serial_pci_realize, then increment the port count
(pci->ports) as we initialize the serial port cores.

Now pci->ports always holds the number of successfully
initialized ports and we can use multi_serial_pci_exit
to properly cleanup the already initialized bits in case
of a init failure.

In OSX 10.10, the NSOKButton and NSCancelButton constants are deprecated
and provoke compiler warnings. Avoid them by using the
NSFileHandlingPanelCancelButton and NSFileHandlingPanelOKButton constants
instead. These are the documented correct constants for the 10.6-and-up
beginSheetModalForWindow API we use. We also use the same method for
the pre-10.6 compatibility code path, but conveniently the constant
values are the same and the constant names have been present since 10.0.
Preferring the constant names that match the non-legacy API makes more
sense anyway.

Our class QemuCocoaAppController implements the NSApplicationDelegate
interface, and we pass an object of this class to [NSApp setDelegate].
However, we weren't declaring in the class definition that we implemented
this interface; in OSX 10.10 this provokes the following (slighly
misleading) warning:
ui/cocoa.m:1031:24: warning: sending 'QemuCocoaAppController *' to parameter of
      incompatible type 'id<NSFileManagerDelegate>'
    [NSApp setDelegate:appController];
                       ^~~~~~~~~~~~~
/System/Library/Frameworks/Foundation.framework/Headers/NSFileManager.h:109:47:

@property (assign) id <NSFileManagerDelegate> delegate NS_AVAILABLE(10_5,
2_0);
                                              ^

Annoyingly, this interface wasn't formally defined until OSX 10.6, so we
have to surround the relevant part of the @interface line with an ifdef.

The code that tries to test at both compiletime and runtime
for whether CGImageCreateWithImageInRect is supported provokes
a compile warning on OSX 10.3:

ui/cocoa.m:378:13: warning: comparison of function 'CGImageCreateWithImageInRect'
      equal to a null pointer is always false[-Wtautological-pointer-compare]
        if (CGImageCreateWithImageInRect == NULL) { // test if "CGImageCreateWithImageInRect" is
supported on host at runtime
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~    ~~~~

The simplest way to deal with this is just to drop this code,
since we don't in practice support OSX 10.4 anyway. (10.5 was
released in 2007 and is the last PPC version, so is the earliest
we really need to continue to support at all.)
