Add generic_page_range() -- generic page table operation.
Linux has several instances of repeated code to do updates to a range
of PTEs. Mapping memory between domains in Xen also tends to need to
do this quite frequently, to ensure page tables have been constructed
and to look up PTE addresses when making mapping-related hypercalls.
This patch adds a generic PTE walk-and-fill operation that takes a
function pointer to call on leaf entries. direct_remap_area_pages()
is updated to use the new call, ass are abuses of
__direct_remap_area_pages.
This patch also introduces two new helper functions for working with
page tables when mapping memory between domains:
create_lookup_pte_addr() returns the machine address of a PTE,
allocating intermediate page tables as necessary. touch_pte_range()
ensures that page tables exist for a virtual address range.
Many of the existing linux page table operations (e.g. zap/remap/etc)
could be modified to use this interface, which would potentially
shorten up mm/memory.c a bit.

Allow use of grant tables for netdev tx+rx rings. Code is kinda
ugly due at least in part to the fact that we still have separate
_TX and _RX grant config options - expect this to be unified soon.

New 'network-bridge' script that uses ifdown/ifup to configure the interface rather than trying to transfer addresses and routes. (Suggested by Gerd Knorr)
Although Li Ge has had problems with this script he had trouble with the previous too. I think this new one should work for more people, particularly those using DHCP on their primary dom0 interface.
Debugging is currently enabled ("sh -x") so a log of the script's execution is output to /var/log/xend.log
