This patch adds the functions needed to handle IPv6 packets. ICMPv6 and
NDP headers are implemented.
Slirp is now able to send NDP Router or Neighbor Advertisement when it
receives Router or Neighbor Solicitation. Using a 64bit-sized IPv6
prefix, the guest is now able to perform stateless autoconfiguration
(SLAAC) and to compute its IPv6 address.
This patch adds an ndp_table, mainly inspired by arp_table, to keep an
NDP cache and manage network address resolution.
Slirp regularly sends NDP Neighbor Advertisement, as recommended by the
RFC, to make the guest refresh its route.
This also adds ip6_cksum() to compute ICMPv6 checksums using IPv6
pseudo-header.
Some #define ETH_* are moved upper in slirp.h to make them accessible to
other slirp/*.h

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

Casting a pointer to an integer value must use uintptr_t or intptr_t
(not long) for portable code. MinGW-w64 requires this because
sizeof(long) != sizeof(void *) for w64 hosts, so casting to long
raises a compiler warning.
I use uintptr_t instead of intptr_t because changing the sign does not
matter here and casting pointers to unsigned values seems more
reasonable (the unsigned value is a non negative offset.

There is no need to have a second set of integral types.
Replace them by the standard types from stdint.h.

According to the FSF, the 4-clause BSD license, which slirp is covered under,
is not compatible with the GPL or LGPL[1].

There are three declared copyright holders in slirp that use the 4-clause
BSD license, the Regents of UC Berkley, Danny Gasparovski, and Kelly Price.
Below are the appropriate permissions to remove the advertise clause from slirp
from each party.
Special thanks go to Richard Fontana from Red Hat for contacting all of the
necessary authors to resolve this issue!

Hi Richard,
I have no objection to having Slirp code in QEMU be licensed under the
3-clause BSD license.
Thanks for taking the effort to consult me about this.

Subject: Re: Slirp license
Thanks for contacting me, Richard. I'm glad you were able to find
Dan, as I've been "keeping the light on" for Slirp. I have no use for
it now, and I have little time for it (now holding onto Keenspot's
Comic Genesis and having a regular US state government position). If
Dan would like to return to the project, I'd love to give it back to
him.
As for copyright, I don't own all of it. Dan does, so I will defer to
him. Any of my patches I will gladly license to the 3-part BSD
license. My interest in re-licensing was because we didn't have ready
info to contact Dan. If Dan would like to port Slirp back out of
QEMU, a lot of us 64-bit users would be grateful.
Feel free to share this email address with Dan. I will be glad to
effect a transfer of the project to him and Mr. Bellard of the QEMU
project.
