Add capability for 3c59x driver to use memory-mapped PCI I/O resources.
This may improve performance for those devices so equipped.  This will be
the default behaviour for IS_CYCLONE and IS_TORNADO devices.  Additionally,
it can be enabled/disabled individually for up to MAX_UNITS number of
devices via the use_mmio module option or for all units via the
global_use_mmio option.  The use_mmio option overrides the global_use_mmio
option for those devices specified.

This patch adds some missing pci-related calls to the suspend and resume
routines of the 3c59x driver.  It also makes the driver free/request IRQ on
suspend/resume, in accordance with the proposal at:

Many drivers use skb->tail unnecessarily.

In these situations, the code roughly looks like:

	dev = dev_alloc_skb(...);

	[optional] skb_reserve(skb, ...);

	... skb->tail ...

But even if the skb_reserve() happens, skb->data equals
skb->tail.  So it doesn't make any sense to use anything
other than skb->data in these cases.

Another case was the s2io.c driver directly mucking with
the skb->data and skb->tail pointers.  It really just wanted
to do an skb_reserve(), so that's what the code was changed
to do instead.

Another reason I'm making this change as it allows some SKB
cleanups I have planned simpler to merge.  In those cleanups,
skb->head, skb->tail, and skb->end pointers are removed, and
replaced with skb->head_room and skb->tail_room integers.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
