In if_ndis.c:ndis_attach(), temporarily set the IFF_UP flag while

calling the haltfunc. If an interrupt is triggered by the init
or halt func, the IFF_UP flag must be set in order for us to be able
to service it.

In kern_ndis.c: implement a handler for NdisMSendResourcesAvailable()
(currently does nothing since we don't really need it).

In subr_ndis.c:
	- Correct ndis_init_string() and ndis_unicode_to_ansi(),
	  which were both horribly broken.
        - Implement NdisImmediateReadPciSlotInformation() and
	  NdisImmediateWritePciSlotInformation().
	- Implement NdisBufferLength().
	- Work around my first confirmed NDIS driver bug.
	  The SMC 9462 gigE driver (natsemi 83820-based copper)
	  incorrectly creates a spinlock in its DriverEntry()
	  routine and then destroys it in its MiniportHalt()
	  handler. This is wrong: spinlocks should be created
	  in MiniportInit(). In a Windows environment, this is
	  often not a problem because DriverEntry()/MiniportInit()
	  are called once when the system boots and MiniportHalt()
	  or the shutdown handler is called when the system halts.

With this stuff in place, this driver now seems to work:

ndis0: <SMC EZ Card 1000> port 0xe000-0xe0ff mem 0xda000000-0xda000fff irq 10 at device 9.0 on pci0
ndis0: assign PCI resources...
ndis_open_file("FLASH9.hex", 18446744073709551615)
ndis0: Ethernet address: 00:04:e2:0e:d3:f0
