net: remove implicit peer from offload API

The virtio_net offload APIs are used on the NIC's peer (i.e. the tap
device). The API was defined to implicitly use nc->peer, saving the
caller the trouble.

This wasn't ideal because:
1. There are callers who have the peer but not the NIC. Currently they...

net: extend NetClientInfo for offloading

Some new callbacks have been added to generalize the operations done
by virtio-net and vmxnet3 frontends to manipulate TAP offloadings.

net: make tap offloading callbacks static

Since TAP offloadings are manipulated through a new API, it's
not necessary to export them in include/net/tap.h anymore.

net: change vnet-hdr TAP prototypes

The tap_has_vnet_hdr() and tap_has_vnet_hdr_len() functions used
to return int, even though they only return true/false values.
This patch changes the prototypes to return bool.

net: declare struct iovec in checksum.h to fix compiler warning

The checksum calculation header exports a function that refers to
struct iov defined in iov.h. Without including the former, build
fails like this:

net: disallow to specify multicast MAC address

[Assigning a multicast MAC address to a NIC leads to confusing behavior.
Reject multicast MAC addresses so users are alerted to their error
straight away.

The "net/eth.h" in6_addr rename prevents a name collision with...

net: Rename send_queue to incoming_queue

Each networking client has a queue for packets that could not yet be
delivered to that client. Calling this queue "send_queue" is highly
confusing as it has nothing to to with packets send from this client but
to it. Avoid this confusing by renaming it to "incoming_queue"....

net: add support of mac-programming over macvtap in QEMU side

Currently macvtap based macvlan device is working in promiscuous
mode, we want to implement mac-programming over macvtap through
Libvirt for better performance.

Design:
QEMU notifies Libvirt when rx-filter config is changed in guest,...

hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....

net: increase buffer size to accommodate Jumbo frame pkts

Socket buffer sizes were hard-coded to 4K for VDE and socket netdevs. Bump this
up to 68K (ala tap netdev) to handle maximum GSO packet size (64k) plus plenty
of room for the ethernet and virtio_net headers....
