Subject: Add InOsEmuPkg. Like UnixPkg and Nt32Pkg, but EFI code can be common
 and does not require including system include files. Currently only Unix
 64-bit is supported and it has only been tested on Mac OS X. Not all features
 are ported over, but GOP, via X11,  and access to local file systems are
 supported and you can boot to the shell.
