Instead of sending ICMP ECHO or UDP packets, this mode opens a TCP
connection to the port of choice (80 by default) and sets IP_TTL
or IPV6_UNICAST_HOPS to control the TTL of the outgoing SYN packet.
Instead of using ICMP ECHO sequence or UDP destination port, the
source port number is used to track how many hops away a router is.
For getting the final hop, sockets are left open until a timeout
is reached (10 seconds default) and a write is attempted as soon
as the socket becomes available for writing. Anything other than
a succesful write or a "Connection refused" error is ignored.

Use format +git:XXXXXXXX
The colon is kinder to Debian than a dash and seems stylistically
better. The dash feels as though it introduces another version level,
e.g. -rc1-alpha2. We could just do +gitXXXXXXXX but as git commit
hashes are in lowercase hexadecimal the result can be something really
ugly like +giteaf0cb71. It's also easier to select the commit hash
for a copy/paste operation when there is something to separate it.

Add git version handling to build system
When building from a git tree, the version number built into the
binary will be appended with +git-XXXXXXXX.
The base version number is stored in-tree in configure.in and is that
of the last tagged release. Presumably the git version is later than
the last tag, so we use '+git' rather than '-git' to produce the
correct the lexical sort order -- though of course the sort order
between any two git revisions can only be determined from the git tree
rather than from a lexical sort.

Add -z / --show-ip support
This new option displays both the hostname and the IP address of a
host in the path. This is particularly important when the hostname
determined by a reverse lookup has no corresponding forward record.
This is similar to the -b (both) option in tracepath, but -b was
already taken in mtr for --bitpattern.
Using this option also implies -w / --report-wide as this option isn't
terribly useful without it in report mode.
In general we endeavor to only show the IP address once per line, but
in the split view we consistently add a separate field for IP address
to the output.
