Also calculate TCP checksums.

Fenner got this inverted through a misunderstanding between us.

dbee325068 Actually use gen_prep() and gen_check(), instead of udp_prep() and 
udp_check(), for unknown protocols.

eac66622a0 Allocate and clear the correct number of bytes for a 
struct fd_set that should be able to hold sock + 1 bits.
Before, it was apparently assumed that an fd_mask has
the same size as type char.

a918f16a94 Defining usage() "__dead" is just ridiculous. It also won't compile with 
a June 2000 GCC 2.96 snapshot.

255065aa3b Add a min TTL flag to go along with the max TTL flag. That is, this flag 
allows you to start tracing at a hop number other than 1.

f5004fb09b Add the capability for traceroute(8) to send packets of any IP protocol 
instead of just UDP; an alternate protocol is specified by '-P proto'.
This is useful for finding routers that are blocking packets based on
IP protocol.  New handlers can be added fairly easily to do protocol-
specific things.

5ade368c37 If the user provided a large enough argument to the -w option, the sum 
would overflow and you'd end up doing select() with a negative timeout.

b223204418 Paul objected to my previous change. This adds the same functionality 
(implemented better, admittedly) with a new option, '-S'.  If the
maintainers of traceroute (Van?) add a -S option, we will then be in
conflict.

Also added a too-brief description of the option in the man page.  Someone
with a better command of English than I at the moment should probably look
over it and rephrase it.
