625a526b32 slirp: improve send_packet() callback
Use a more descriptive name for the callback.

Reuse the SlirpWriteCb type. Wrap it to check that all data has been written.

Return a ssize_t for potential error handling and data-loss reporting.

a9d8b3ec43 slirp: replace remaining qemu headers dependency
Except for the migration code which is gated by WITH_QEMU, only
include our own headers, so libslirp can be built standalone.

d846b927a6 slirp: use a callback structure to interface with qemu
This will bring slirp a bit forward to the state of an independent
project.

Let's make the slirp interface a bit more library-like.
Associate the slirp_output() with a Slirp context.

47335eeea8 slirp/ncsi: add checksum support
The checksum field of a NC-SI packet contains a value that may be
included in each command and response. The verification is optional
but the Linux driver does so when a non-zero value is provided. Let's
extend the model to compute the checksum value and exercise a little
more the Linux driver.

See section "8.2.2.3 - 2's Complement Checksum Compensation" in the
Network Controller Sideband Interface (NC-SI) Specification for more
details.

b2d1678fa1 slirp/ncsi: add a "Get Parameters" response
Command 0x17 'Get Parameters' is used to get configuration parameter
values currently in effect on the controller and it is mandatory in
the NS-CI specification.

Provide a minimum response to exercise the kernel.

47bb83cad4 slirp: add a fake NC-SI backend
NC-SI (Network Controller Sideband Interface) enables a BMC to manage
a set of NICs on a system. This model takes the simplest approach and
reverses the NC-SI packets to pretend a NIC is present and exercise
the Linux driver.

The NCSI header file <ncsi-pkt.h> comes from mainline Linux and was
untabified.
