Support for DHCP options (like static routes, alternate DNS server, etc)

This is a desired feature for me, too. What I miss:

• Advertise search domain in DHCPv4 option 15, not only option 119. Some software expect that.
• Serve NTP server list with DHCPv4 and DHCPv6.
• (unrelated)Put current lease list somewhere in /tmp, like dnsmasq does

This feature would be very useful. Currently I'm using a few dhcp options with dnsmasq, and I would much prefer to use odhcpd wholly instead.

The options I'm currently using with dnsmasq are:

list dhcp_option '43,01:04:00:00:00:02' - disables NetBIOS
list dhcp_option '252,"\n"' - stops Windows asking for proxy information
list dhcp_option '15,lan' - search domain
list dhcp_option '6,10.10.10.254' - dns server (because dnsmasq is in parallel with unbound)

I implemented the "alternative default gateway", it's called router option in the RFC
alternative DNS servers as possible right now: use "dns" option :)

@mikejuni can you try/review https://github.com/mehlis/odhcpd/compare/implement-dhcp4-router-config?expand=1

I can try this with openwrt on 12th august, if new code is working I'll open a PR!

Patch looks good to me. Feel free to make a PR and I will merge it.

@mikejuni https://github.com/sbyx/odhcpd/pull/20 is merged, from my perspective odhcpd is a replacement for dnsmasq now

@sbyx this issue is addressed from my point of view

[mikejuni]

I've reviewed the relevant patches. Noted that it unfortunately still does not provide the configuration options that I've been using in DNSMASQ. I've a couple of DHCP clients (not all, only a few) that would actually be routed through an alternative router and assigned a different DNS. This means that in the configuration section "host" it should allow overriding default DNS and gateway, or better, allowing allocation of different static routes as well.

I understand that this is very complex but DNSMASQ for now works very well doing so, plus with an ipv6 enabled DNSMASQ it also allocates IPv6 address for my SIXXS tunnel as well.
