I've got this working. The tricky part was a driver/application can mix malloc forms. If the driver links against this library all the allocations come from the OS service, but if a protocol or EFI boot service return an allocated buffer it will still use the EFI allocation. The gasket code can detect this and do the right thing, as the emulator is passing up the memory map to EFI.
You can now use the OS based malloc debugging tools in an EFI driver or appliaction. On OS X this is libgmalloc, also called guard malloc.

This is a fix for XCODE/XCLANG. I'm still seeing an issue, but the stat info for the filesystem is now correct.

Added OS malloc and free so we can make MemoryAllocationLib instance that uses OS guard malloc. This will allow all the debug support built into the OS for finding malloc bugs to be used with a driver in the emulator.

For IA32 builds, if /lib32 and /usr/lib32 exist,
they will be used instead of /lib and /usr/lib.
For X64 builds, if /lib64 and /usr/lib64 exist,
they will be used instead of /lib and /usr/lib.

Start using MdeModulePkg MetronomeDxe driver. Add PEI and DXE_CORE TimerLibs that just call back to the emulator. Add a DXE/UEFI TimerLib that also does a gBS->WaitForEvent() if the stall is for a long period of time. Change the Thunk API for Sleep to nanoseconds.

This implementation only covers a few BaseMemoryLib functions.

This gIdleLoopEventGuid event signals the Cpu that it should go into
the idle state waiting for any events.
CpuSleep() is used in this implementation to make the Cpu wait for
the next interrupt (WFI instruction).

Previously the CPU driver had a dependency on the GIC driver.
But by design is should be the opposite. The CPU driver installs the
CPU protocol that exposes the exception registration function.
And then, the interrupt controller registers its IRQ handler through
this interface.

At this point IA-32 emulator boots the shell with an X11 GOP window. Block IO seems to have an issue that needs to be debugged.

There are still issues with the IA-32 gasket code. Mostly having to do with yank put bugs not accounting for UINT64 returns and arguments. Currently the IA-32 build crashes in the timer callback since it is UINT64, function ptr but the gasket is UINTN UINTN.

Added a CpuSleep () API to the Emulator Thunk. We needed to do this as the Stall() works hard to not get broken by the timer tic (POSIX signal). nanosleep() gets interrupted by the timer signal so it is a good emulator of a CpuSleep(); I was also able to remove some stalls in the X11 keyboard and mouse checking events, now that the gIdleLoopEventGuid was added.

Devices get the block size via ioctl, but for a file the block size needs to be set. Default to 512, but optionally allow other values, like 2048/0x800 for ISO CD-ROM images. Also updated the comments in .DSC and .DEC files.

When the MdeModulePkg gCoreEventIdleGuid event is signaled,
CpuSleep is called. This will cause the CPU to sleep until
the next interrupt occurs.
