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.

+  )

+/*++

+

+Routine Description:

+

+  The WaitForTick() function waits for the number of ticks specified by

+  TickNumber from a known time source in the platform.  If TickNumber of

+  ticks are detected, then EFI_SUCCESS is returned.  The actual time passed

+  between entry of this function and the first tick is between 0 and

+  TickPeriod 100 nS units.  If you want to guarantee that at least TickPeriod

+  time has elapsed, wait for two ticks.  This function waits for a hardware

+  event to determine when a tick occurs.  It is possible for interrupt

+  processing, or exception processing to interrupt the execution of the

+  WaitForTick() function.  Depending on the hardware source for the ticks, it

+  is possible for a tick to be missed.  This function cannot guarantee that

+  ticks will not be missed.  If a timeout occurs waiting for the specified

+  number of ticks, then EFI_TIMEOUT is returned.

+

+Arguments:

+

+  This       - The EFI_METRONOME_ARCH_PROTOCOL instance.

+  TickNumber - Number of ticks to wait.

+

+Returns:

+

+  EFI_SUCCESS - The wait for the number of ticks specified by TickNumber

+                succeeded.
