/** @file
Support routines for memory allocation routines based
on boot services for Dxe phase drivers using OS malloc.
OS malloc is used so OS based malloc debugging tools can be used.
If a single driver links against this lib protocols from other
drivers, or EFI boot services can return a buffer that needs to
freed using the EFI scheme. This is why the gEmuThunk->Free ()
can detect if the memory rang is for EFI so the right free can be
called.
