This patchset takes the original patch from Maxim,
https://www.mail-archive.com/qemu-devel@nongnu.org/msg569573.html
and updates it.

Option hostfwd is extended to support ipv6 addresses.
Commands hostfwd_add, hostfwd_remove are extended as well.

The libslirp part of the patch has been committed upstream,
and is now in qemu. See patch 1/5.

Changes from v4:

1/5 slirp: Advance libslirp submodule to add ipv6 host-forward support
NOTE TO REVIEWERS: I need some hand-holding to know what The Right
way to submit this particular patch is.

- no change

2/5 util/qemu-sockets.c: Split host:port parsing out of inet_parse

- move recognition of "[]:port" to separate patch
- allow passing NULL for ip_v6
- fix some formatting issues

3/5 inet_parse_host_and_addr: Recognize []:port (empty ipv6 address)

- new in this patchset revision

4/5 net/slirp.c: Refactor address parsing

- was 3/4 in v4
- fix some formatting issues

5/5 net: Extend host forwarding to support IPv6

- was 4/4 in v4
- fix some formatting issues

Changes from v3:

1/4 slirp: Advance libslirp submodule to add ipv6 host-forward support

- pick up latest libslirp patch to reject ipv6 addr-any for guest address
  - libslirp currently only provides a stateless DHCPv6 server, which means
    it can't know in advance what the guest's IP address is, and thus
    cannot do the "addr-any -> guest ip address" translation that is done
    for ipv4

2/4 util/qemu-sockets.c: Split host:port parsing out of inet_parse

- this patch is new in v4
  - provides new utility: inet_parse_host_and_port, updates inet_parse
    to use it

3/4 net/slirp.c: Refactor address parsing

- this patch renamed from 2/3 to 3/4
- call inet_parse_host_and_port from util/qemu-sockets.c
- added tests/acceptance/hostfwd.py

4/4 net: Extend host forwarding to support IPv6

- this patch renamed from 3/3 to 4/4
- ipv6 support added to existing hostfwd option, commands
  - instead of creating new ipv6 option, commands
- added tests to tests/acceptance/hostfwd.py

Changes from v2:
- split out libslirp commit
- clarify spelling of ipv6 addresses in docs
- tighten parsing of ipv6 addresses

Change from v1:
- libslirp part is now upstream
- net/slirp.c changes split into two pieces (refactor, add ipv6)
- added docs
