[PATCH v2 0/9] IPv6 Support

[Samuel Mendoza-Jonas]

This adds support for parsing and configuring IPv6 addresses in
Petitboot. Changes largely include updating the URL parsing and tracking
which has been configured.
This depends on updates to Busybox's udhcpc6 client which add DHCPv6
support, which are now upstream.

Changes in v2:
Use DHCPv4 and DHCPv6 simultaneously, drop petitboot,ipv6 parameter.
Improve network availability check in load_url_async().
Simplify field validation

Samuel Mendoza-Jonas (9):
  lib: Add support and helpers for IPv6 host addresses
  discover/sysinfo: Set IPv6 addresses
  lib/system: Add udhcpc6
  utils/pb-udhcpc: Recognise DHCPv6 parameters
  discover: Support IPv6 addresses
  discover/user-event: Use bootfile_url if available
  discover/pxe-parser: Parse simple iPXE scripts
  discover: Determine connectivity with getaddrinfo()
  ui/ncurses: Allow IPv6 addresses in address fields
