Joachim WibergandTobias Waldekranz 228891935d dhcp-client: allow setting hostname, and update /etc/hosts
This should be the last outstanding issue to fix #278.  Please note,
it is undefined what happens if you have two DHCP clients that request
hostname, and changing hostname from NETCONF at runtime will overwrite
any hostname set by the DHCP client.

If we don't get subnet, then just set the IP address.

Joachim WibergandMattias Walström 2fa5dcfea0 board/common: major refactor of udhcpc script
- New log() function replaces stdout logging
 - New set_dhcp_routes() and clr_dhcp_routes() functions
   - Set all option 121 routes with same metric
   - Set all option 3 routers with increasing metric (this is what the
     reference udhcpc scripts do, and RFC says the routers should be
     listed in order of preference ...)
   - Clearing routes must, like IP addresses, be done both by interface
     and protocol.  This refactor makes sure to delete any DHCP routes
     set on the given interface (in case options change)
 - Use resolvconf per-interface search+nameserver
 - Cache IP lease so we can ask for it back later
 - On deconfig|leasefail|nak, make sure to clean up anything that might
   be lingering from this interface.  E.g., we can get leasefail when a
   server denies our request to prolong a lease.
 - On renew|bound, refresh routes, and set search+dns + NTP servers

Richard AlpeandJoachim Wiberg 59c02bd7f3 udhcpc: flush dhcp addresses in default.script
Flush addresses during shutdown and renewal with new address.
This is kind of a hack and needs further testing.

Richard AlpeandJoachim Wiberg f75053c931 udhcpc: convert default.script to use ip not ifconfig
This fixes one bug in Infix, namely that dhcp removes all other
statically configured addresses. However it introduces a new one
where dhcp renewals with new ip addresses are added as "duplicates",
we fix this in a later commit in this patchset.
