Begin the first phase of trying to add IRP support (and ultimately

USB device support):

- Convert all of my locally chosen function names to their actual
  Windows equivalents, where applicable. This is a big no-op change
  since it doesn't affect functionality, but it helps avoid a bit
  of confusion (it's now a lot easier to see which functions are
  emulated Windows API routines and which are just locally defined).

- Turn ndis_buffer into an mdl, like it should have been. The structure
  is the same, but now it belongs to the subr_ntoskrnl module.

- Implement a bunch of MDL handling macros from Windows and use them where
  applicable.

- Correct the implementation of IoFreeMdl().

- Properly implement IoAllocateMdl() and MmBuildMdlForNonPagedPool().

- Add the definitions for struct irp and struct driver_object.

- Add IMPORT_FUNC() and IMPORT_FUNC_MAP() macros to make formatting
  the module function tables a little cleaner. (Should also help
  with AMD64 support later on.)

- Fix if_ndis.c to use KeRaiseIrql() and KeLowerIrql() instead of
  the previous calls to hal_raise_irql() and hal_lower_irql() which
  have been renamed.

The function renaming generated a lot of churn here, but there should
be very little operational effect.
