Marvin Drees 3c1f0e0281 Handle IA_NA/IA_PD requests and config options in DHCPv6 (#147)
* feat(dhcpv6): handle IA_NA/IA_PD requests and config options

Adds the DHCPv6 client request exchange with IA_NA/IA_PD handling,
reconfigure-renew (RFC 8415), DNS server and domain search options
(RFC 3646) and NTP server suboptions (RFC 5908).

* fix(dhcpv6): bound server-supplied option counts to prevent OOM

A DHCPv6 server may place arbitrarily many DNS servers, search domains,
NTP entries and delegated prefixes in a single message (RFC 8415). The
client appended every entry into growable slices with no upper bound, so
a malicious or misconfigured server could drive unbounded allocation.

Add a configurable Limits to RequestConfig (with safe defaults) capping
each repeated option. The backing arrays are sized to their caps once in
BeginRequest and reused across resets, so parsing a server message now
performs no allocation and stored entries stay bounded.

Add tests asserting the caps are enforced against a flooded Reply and that
option parsing is allocation-free after BeginRequest.

Ron Evans fa609ea54f fix: two fixes for dhcp/ap (#136)
* feature: ipv4 broadcast support

* stackip4 method receiver varname

* Incorporate strict test timing for TestStackGoTCPDialRetriesPendingControl (#135)

* rewrite tinygo failing test to be more real-time

* use channels to scheduler stack

* fix flakiness by increasing timeout and move implementation to top of file

* fix(dhcp): use chaddr as lookup key and patch Ethernet dst on Offer/Ack

- Client lookup in Demux() now keys on chaddr when no OptClientIdentifier
  is present. It previously used ciaddr which is 0.0.0.0 during initial lease
  acquisition, causing MsgRequest to fail to match any client (RFC 2131 §4.3.1)
- In Encapsulate(), overwrite Ethernet dst with client.hwaddr when packet is
  embedded in an IP frame (offsetToIP >= 14), per RFC 2131 §4.1. It previously
  sent to gwmac which clients without an ARP entry could not receive

* fix: accept 255.255.255.255 aka bradcast dst in demux4

This fixes a problem with accept 255.255.255.255 dst in demux4 which previously dropped when stack had a static IP.
