remove IPv4 csum offloading for xennet(4) - it's not complete, and even
if it was, it doesn't work with Linux Dom0 as it expects the IPv4 csum present

actually in data_validated case, there is no need to inspect the data for Rx,
simply set the supported csum offload flags to skip the software csum
verification

Changes since 1.6: +41 -15 lines
Diff to previous 1.6 (colored)

use NET[RT]XF_data_validated flag to mark when Tx packet has valid
checksum; this is used to skip software checksum validation on
xennet Rx side when configured for Rx offloading

in Dom0 assume that checksum is valid when the Tx mbuf has no offload flags
- in that case either it's local packet where checksum has just been
computed in software, or forwarded external packet already
verified when received on Dom0

practical offshot of this is that DomU doesn't re-verify checksum of
packets forwarded from external hosts, e.g. via bridge(4)

drop the disabled M_EXT_ROMAP mbuf code, convert xennet_checksum_fill()
to use in_undefer_cksum() instead of custom code to compute the checksum
for Rx packets, and set csum_data appropriately for eventual hw offloading

make it possible to skip the sw checksum computation by appropriate Rx
flag similarily as we do for Tx

XXX for now, the Rx flag is mostly for testing as it only works for
dom0<->domu, need some further network stack changes to arrange for
the checksum to be eventually computed when packets goes outside xen

Prepare for xenamd64:
- kill xen/i386/identcpu.c, use i386/i386/identcpu.c instead (with a few
  #ifndef XEN)
- move some files that can be shared between i386 and amd64 from
  xen/i386 to xen/x86 (or to xen/xen for non-cpu-specific code)
- split assembly out of xen/include/hypervisor.h to xen/include/hypercalls.h
- use <xen/...> instead of <machine/...> for cpu-independant include files.

more work needed here, i386-specific files should got out of arch/xen to
arch/xeni386, and more code shared with arch/i386.
