This resolves some problems in the endpoint disable
patch I sent recently:

  - wasn't un-halting some endpoints
  - was clobbering ep0 setup in some cases.

The calling task must have a valid reclaim_state when running page
reclaim.  But I had forgotten about shrink_all_memory().

Move the PCI core to start using these, enabling proper reference counting
on struct pci_dev.

Adjusts the IPTables targets to handle non-linear packets.
ipt_ULOG untested.

Adjusts the IPTables matches to handle non-linear packets.
Untested: ipt_ah and ipt_esp.

Adjusts the IPTables core to handle non-linear packets.  Extensions
done separately in next patch.  Also, comments about when to set
"me" field in struct ipt_match, ipt_table and ipt_target are
corrected.

Main points:
- receive buffers are decoupled from urbs, so an urb can be
resubmitted with a new buffer before the old buffer is processed.
- the packet reconstruction code is much simpler.
- locking is simplified by the fact that only the tasklet launches
receive urbs
