96b5d3aa91 Actually populate the file field 
Thankfully, it turns out that HTTPBoot carries the same flexibility
as PXE with respect to no-ip answer being merged with an IP answer.

As a bonus, it actually is simpler than PXE, allowing skipping of udp
port 4011.  Of course, we still want to support PXE boot, so that will
need to be implemented.

f0e5572b05 Remove filename from DHCP reply 
filename is ignored if pxeclient anyway.  This will provide a
consistent approach for boot file for dhcp-elsewhere and
fixed ip clients alike.

Also add some TODO about how to enable DHCPREQUEST
processing when the time comes, as today the code skipping
option parsing for DISCOVER packets trips up the ability
to continue.  We must make sure we don't call discovery
handler again for REQUEST after doing so for DISCOVER.

fcd73399fa Add IP and UDP header to OFFER attempt 
It d oesn't quite work, but it looks convincing.  UDP checksum may
need to be added, and beyond that explore changes to the payload since
it is likely not enough DHCP was provided.

b7d85b2166 Switch to ctypes for sendto 
First, IP level sendto doesn't give the freedom to send 25.255.255.255
out of the interface desired.  So have to go link layer.

Second, while python can do sendto, we have the interface index number
from recvmsg (which was ctypes).  python expects the name instead
(wwhich it promptly turns... back into the index we start with).  I
could have added code to get the name using some syscalls which would
have been work and produced more system calls, or added the code to
directly use sendto, which would also be efficient at runtime.

So I chose to use ctypes for both recvmsg and sendto here.

6ade0952c7 Workaround incorrect TLS clients 
Standards compliant TLS clients require
that IP addresses be compared against
IP type SAN fields.

However, some firmware ignores IP fields and only checks DNS fields.

Workaround and provide compatibility
by duplicating the IP as DNS and IP fields.

Also, clean up the temporary config file when done.

49b8e12a01 Update TODO 
We have now done IP_PKTINFO, but there is a potential TODO
if wanting to properly honor unicast request.

For now, will just do always-broadcast as the options to do unicast
are more complex to do (either construct the packets or inject neigh
entry manually)
