datapath: Fix compilation on newer old-style Xen kernels.
		
Some ports of Xen (such as Debian Lenny's) use the old style
Xen checksumming fields on newer kernels.  Normally the code that
deals with those fields isn't used at all on newer kernels.  This
updates the checksumming pointer code with some changes from Lenny
Xen since it is cleaner and works well with our existing compatibility
layer.

datapath: Support CHECKSUM_PARTIAL on older kernels.
		
On older kernels we would not correctly update partial checksums
because it was difficult to determine the type of checksum.  This
uses some hints to infer the correct type of checksum so that it
can be updated.  It also allows us to correctly define
CHECKSUM_PARTIAL, which is important for other components.

datapath: Transport port is not part of psuedoheader.
		
While updating the checksum after changing the transport port,
we indicated that this was a change to the psuedoheader.  Since
this is not the case, it could produce an incorrect checksum.
