Remove the real-time "appears to be up" message. I realized I shouldn't have

made such a big UI change with no discussion. Anyway, the message should have
gone within the ((hss->target->flags & HOST_UP) == 0) block so that the message
is printed only once per target.

...
Always update srtt, rttvar, and timeout for every response, even if we don't adjust congestion control or send delay variables.
Be more careful about checking gstats->sendOK when sending retransmits.
Previously, it was only checked once per traversal of the incomplete
hosts list, which meant that enough probes could be sent in a round to
exceed the congestion window. Explanatory pictures are at
http://www.bamsoftware.com/wiki/Nmap/PerformanceGraphs#retransmit-sendOK .
This needs some more testing to see what effect it has on scan times. My
instinct says it will slow them down, because retransmits will be sent
no faster than before, and retransmits will be more likely to be
responded to, leading to more drops. On the other hand, correctly
detecting a drop and marking a host up is better than blasting
retransmits faster than they can be responded to.

Look out, world, here comes the Nmap massping migration!
...
This is the merging of the code that was previously in
/nmap-exp/david/nmap-massping-migration. These are all the big changes
that get rid of massping in favor of doing host discovery using
ultra_scan.
For now, there is a toggle that turns these new changes off. Undefine
NEW_MASSPING in targets.cc to go back to the old code. All of that will
be deleted eventually.
There are likely a few more changes that will be made to this system in
the near future. Those will be made in
/nmap-exp/david/nmap-massping-migration and merged back.
Don't release this just yet, because I'm going to make a few more
commits real quick to remove some debugging stuff.
(Note to self: this merge back was from r5693 in
/nmap-exp/david/nmap-massping-migration.)

Adding Snprintf() and Vsnprintf() to nbase/nbase_str.c. This is because of Windows' stupid implementation where it doesn't write a NULL byte at the end of the buffer if the result is truncated. I would've just #defined snprintf and vsnprintf to some wrapper function for Windows, but this doesn't work as libdnet and libpcap (and libpcap includes under mswin32) define snprintf to _snprintf and vsnprintf to _vsnprintf like we do, and through the many defines they end up being available in the Nmap sources. Vsnprintf() uses vsnprintf() (and writes a NULL byte at the end if truncated), and Snprintf uses Vsnprintf().

Staying on the safe side when matching TCP flags on one part in scan_engine.cc. Instead of testing th_flags == TH_SYN|TH_ACK, it tests if (th_flags & TH_SYN|TH_ACK) == TH_SYN|TH_ACK. It's looks like it's done 'correctly' everywhere else. I can't really think of a real situation where we'd recieve any extra flags when doing a SYN scan, but we could (and it's better than having a false negative anyway).

Remove some duplication in get_pcap_result() in scan_engine.cc. probe->protocol() is all ready checked against ip2->ip_p earlier (the two I'm removing indirectly check against ip2->ip_p: look at the removed part and what ip2->ip_p is tested against in the surrounding if()s). Then a little lower in the function, that whole if() block can be removed because it's the same as what's done in that switch() block. The same error() and hdump() are used in the default case. I could've kept the if(), but this keeps is simple.

Fixed IPProto Scan on localhost when using --data-length to add at least 8 bytes of data. There is a check to see if the packet is at least 28 bytes long (IP header and 8 bytes of data), and if it's at least that big it's considered good. So if the protocol matches, it's considered open. The problem was we didn't check for our own probes, so if we scan localhost with --data-length >=8, everything was labeled open.

Use dnet headers for TCP and UDP. This allows us to remove netinet tcp.h and udp.h references, the udphdr_bsd stuff, and the TH_ECE/TH_CWR #defines in tcpip.h. That was easy, but we (Fyodor and I) came to the conclusion that IP and ICMP aren't worth the hassle to switch (I was testing TCP, UDP and IP in my branch). The struct icmp_hdr in dnet isn't setup anything like what we're using now. Then, struct ip_hdr uses ip_addr_t (typedef'd to uint32_t in that ip.h) instead of struct in_addr for the IP addresses, and that would require some dnet modifying to work right. We might be able to come up with some elegant solution for IP, but probably not for ICMP. For now, they're still left up to netinet (or tcpip.h).

Merging my UDP localhost patch. It fixes the UDP scan on localhost picking up it's own port. It also fixes the TCP one so that it doesn't print a message (with -d) about receiving a response with unexpected flags (like getting a SYN for a SYN scan because it's our port). The problem was that the IP ID wasn't ntohs()'d while checking for this, so we still saw our port on UDP. I simply copied this to the TCP part to avoid the message.

Merging my IGMP -sO patch. This adds build_igmp_raw() to easily build IGMP packets and uses it for -sO. Systems respond more when these packets are sent with an actual IGMP header. The RFC says they MUST verify the checksum, so that's most likely why I always got open|filtered instead of open. Since the different IGMP types all seem to have the checksum in the same place in the packet, it should at least tell us if it's supported or not even if the rest of the header is bogus (because the rest of the header has changed a little bit between the versions).
