Added pxe_netdev; a slight hack for now, but will need to be done properly for the PXE UNDI API anyway.

Derive xid dynamically from the netdev, so that we can call create_dhcp_packet() from pxe_preboot.c, after the dhcp_session is long gone.

Remove unused attribute from __table macros; the tables are no longer static since otherwise gcc4 optimises them away completely. Also, it really *is* an error if the table start and end are unused, so they certainly shouldn't be marked with attribute unused.

Split DHCP packet creation into two parts: creating the basic packet structure, and populating it with options. This should allow us to use the same basic options list for both DHCPDISCOVER and DHCPREQUEST, plus making it much easier to set the non-constant parameters (e.g. requested IP address) in request packets.
