[PATCH installer 0/8] add IPv6 SLAAC and v6-only support

[Christoph Heiss <c.heiss@proxmox.com>]

Most glaringly, neither the GUI nor TUI handled IPv6-only setups
correctly, in that the pre-filled values for the networking setup simply
defaulted to the IPv4 defaults.

Patch #1-#4 rework the GUI side of things.

Patch #5 enables support for /127 and /128 IPv6 CIDRs, which we do
support elsewhere.

Finally, patch #8 enables sending router solicitations when the
installer starts, such than any IPv6 (SLAAC) configuration is retrieved.

Patches #5-#8 are independent and can be applied individually as such,
if desired.

Christoph Heiss (8):
  install: drop trivial fromjs() wrapper and use JSON::from_json()
  install: move network subroutines to Proxmox::Sys::Net
  gui: use run_env->{network} instead of old run_env->{ipconf}
  sys: net: drop the now-unused `ipconf` runtime environment
    configuration
  sys: net: allow up to /128 netmask for IPv6
  sys: net: ignore ipv6 nameservers with zone identifiers
  common: options: rework network address setup to handle ipv6-only
  unconfigured: try to retrieve IPv6 SLAAC addresses on startup
