f68edb1611 Actually fall back from yiaddr to ciaddr.
The initial implementation of toDhcpResults attempted to get the
leased IP address from ciaddr if yiaddr was 0.0.0.0, but it never
actually did so because a) it used == instead of equals(), and b)
the parsing code never populated mClientIp for a DhcpOfferPacket
or DhcpAckPacket.

Fix this and add a test for it.. Technically DHCP does not use
ciaddr (only bootp uses it), but in 5.0 we would use ciaddr if
yiaddr was 0.0.0.0 and a bit more compatibility shouldn't hurt.

3e979321a5 Set the secs field in the BOOTP header.
We mostly follow RFC 2131, which says that secs is the number of
seconds "since client began address acquisition or renewal
process", and thus set secs to zero on renew. This is different
from our current behaviour, which keeps on counting without
resetting secs to zero on renew.

c8a0f49fee DHCP: Minor cleanups to the packet code.
1. Delete the DhcpStateMachine, since we don't plan to use it.
2. Make all InetAddresses Inet4Addresses, since that's what they
   are.  In order to do this, define INADDR_ANY and
   INADDR_BROADCAST, constants, since Inet4Address.{ANY,ALL} are
   not Inet4Addresses but InetAddresses.

c95a87f30d DHCP: Move the packet code to frameworks/base/services.
There's no need for it to be in frameworks/base/core, since it
will only be used by services.
