  1. Read and write unlinked files with open handles (#1) 

    This allows files that have open handles, but have been unlinked after the handle was opened to still be read and written to without errors. To make this possible, the following changes are made:

* If the user-space daemon implements fgetattr, it will now be called for any unlinked files that have an open handle.
* If a read call comes in, the kext will allow it to proceed if it realizes the vnode is in use (aka there's at least one open handle).
* Same thing for a write call.
