conn->local_port is now network-endian; do not swap when comparing
...
against value in header.
Temporarily disable RX checksumming; it's broken and is holding up
work on higher-layer protocols
.

Reserve space for lower-layer headers when allocating packet buffer.
...
Use pkb_available() rather than pkb_len() (which will always return 0
on a freshly allocated buffer).
udp_send() should assume that the buffer has already been allocated.

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.

Move some static inlines that are likely to be used frequently into
dhcpopts.c as normal functions, to save space.

Add sketch code to reassemble a DHCP packet from our internal "everything
...
is a DHCP option" data structures.
We need this code in order to be able to return a DHCP packet to a PXE NBP
which reflects options from our multiple sources (e.g. NVS and DHCP
server). This is expensive, but necessary. Having paid this cost, we may
as well try to use the same code to generate our DHCP request packets,
since the process is similar.
