Borrow the eject code for OSX from xine-lib-1.2-macos branch, as contributed

Browse Source 
by Matt Messier. This allows to eject disks on Mac OS X without having to
call an external utility.

Incidentally this fixes libcdio eject function on Mac OS X 10.4 and later, as
hditool was moved from /usr/sbin to /usr/bin.

Eject media . Return DRIVER_OP_SUCCESS if successful.
The only way to cleanly unmount the disc under MacOS X is to use the
'disktool' command line utility. It uses the non-public Disk
Arbitration API, which can not be used by Cocoa or Carbon
applications.
The only way to cleanly unmount the disc under MacOS X (before
Tiger) is to use the 'disktool' command line utility. It uses the
non-public DiskArbitration API, which can not be used by Cocoa or
Carbon applications.
Since Tiger (MacOS X 10.4), DiskArbitration is a public framework
and we can use it as needed.
