Since QEMU 7.1 we don't support Ubuntu 18.04 anymore, so the last big
important Linux distro that did not have a pre-packaged libslirp has
been dismissed. All other major distros seem to have a libslirp package
in their distribution already - according to repology.org:
Fedora 35: 4.6.1
CentOS 8 (RHEL-8): 4.4.0
Debian 11: 4.4.0
OpenSUSE Leap 15.3: 4.3.1
Ubuntu LTS 20.04: 4.1.0
FreeBSD Ports: 4.7.0
NetBSD pkgsrc: 4.7.0
Homebrew: 4.7.0
MSYS2 mingw: 4.7.0
The only one that was still missing a libslirp package is OpenBSD - but
the next version (OpenBSD 7.2 which will be shipped in October) is going
to include a libslirp package. Since QEMU 7.2 will be published after
OpenBSD 7.2, we should be fine there, too.
So there is no real urgent need for keeping the slirp submodule in
the QEMU tree anymore. Thus let's drop the slirp submodule now and
rely on the libslirp packages from the distributions instead.

Version 4.7 of slirp provides a new timer API that works better with CFI,
together with several other improvements:
* Allow disabling the internal DHCP server !22
* Support Unix sockets in hostfwd !103
* IPv6 DNS proxying support !110
* bootp: add support for UEFI HTTP boot !111
and bugfixes.
The submodule update also includes 2 commits to fix warnings in the
Win32 build.

An out-of-bounds access issue was found in the SLIRP user networking
implementation of QEMU. It could occur while processing ARP/NCSI
packets, if the packet length was shorter than required to accommodate
respective protocol headers and payload. A privileged guest user may use
this flaw to potentially leak host information bytes.

Various ipv6 structs in the slirp headers are marked QEMU_PACKED,
but they are actually naturally aligned and will have no padding
in them. Instead of marking them with the 'packed' attribute,
assert at compile time that they are the size we expect. This
allows us to take the address of fields within the structs
without risking undefined behaviour, and suppresses clang
-Waddress-of-packed-member warnings.

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
