Start using Availability.h over AvailabilityMacros.h on Mac OS

The former was introduced with Mac OS 10.6 and can also be used
for checking iOS versions, so it's preferable. We still include
the old availability header, and use it in various places in Qt,
and so does the Mac OS frameworks, so there's no need to phase
it out, but for new platform checks we want to use the updated
macros of the form:

  #if __MAC_OS_X_VERSION_MAX_ALLOWED > __MAC_10_7

Ideally you should not use the named version macro, and use 1070
instead, in case you build against an SDK that does not define
the named version yet, but we take care of defining these
in qsystemdetection.h for convenience.
