The software driver must set inuse field in Parallels header to
0x746F6E59 when the image is opened in read-write mode. The presence of
this magic in the header on open forces image consistency check.
There is an unfortunate trick here. We can not check for inuse in
parallels_check as this will happen too late. It is possible to do
that for simple check, but during the fix this would always report
an error as the image was opened in BDRV_O_RDWR mode. Thus we save
the flag in BDRVParallelsState for this.
On the other hand, nothing should be done to clear inuse in
parallels_check. Generic close will do the job right.

The check is very simple at the moment. It calculates necessary stats
and fix only the following errors:
- space leak at the end of the image. This would happens due to
preallocation
- clusters outside the image are zeroed. Nothing else could be done here

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

Put the number of serial ports into a local variable in

Now pci->ports always holds the number of successfully

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.

The code that tries to test at both compiletime and 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.)
