Roughly 2.5 years ago all events taking the ``icmp_conn`` parameter were
removed with 44ad614094 and the NetVar.cc
type not populated anymore.
Remove the left-overs in script land, too.
This commit removes the stepping stone analyzer. It has been deactivated
by default since at least Zeek 2.0, is dysfunctional in cluster settings
and has a bunch of other issued.
Relates to GH-1573
Clang automatically disables deprecation warnings for types used within
already-deprecated contexts, such as if you use a deprecated type inside
of a method that's beeen marked as deprecated. GCC doesn't have this
feature so it spews a lot more warnings. These functions are now wrapped
in pragmas that disable the warnings for the usage.
This controls whether ports given by "udp_content_delivery_ports_orig" and
"udp_content_delivery_ports_orig" are in terms of the UDP packet's
destination port or by the Connection's "responder" port (the former is
the unchanged default behavior).
The Zeek code base has very inconsistent #includes. Many sources
included a few headers, and those headers included other headers, and
in the end, nearly everything is included everywhere, so missing
#includes were never noticed. Another side effect was a lot of header
bloat which slows down the build.
First step to fix it: in each source file, its own header should be
included first to verify that each header's includes are correct, and
none is missing.
After adding the missing #includes, I replaced lots of #includes
inside headers with class forward declarations. In most headers,
object pointers are never referenced, so declaring the function
prototypes with forward-declared classes is just fine.
This patch speeds up the build by 19%, because each compilation unit
gets smaller. Here are the "time" numbers for a fresh build (with a
warm page cache but without ccache):

If dpd_match_only_beginning is disabled, matches of protocol signatures
can be handeld using protocol_late_match. To prevent further matching in
this case, dpd_late_match_stop may be activated.
