a2f2f7a0dd Prevent IP fragment reassembly on packets without minimal IP header
The IP fragment reassembly process assumes a packet contains at least
the minimum IP header, but such a check did not previously occur,
resulting in a heap buffer over-read.  For example, a self-reported
IPv4 IHL field with a value less than minimum IPv4 header length of
20 bytes.  Such packets likely aren't routable on their own, but one
can create an artifical pcap like that or possibly encapsulate it
within another protocol to trigger this bug.

8f1b34b915 Add basic structure for fuzzing targets
General changes:

* Add -D/--deterministic command line option as
  convenience/alternative to -G/--load-seeds (i.e. no file needed, it just
  uses zero-initialized random seeds).  It also changes Broker data
  stores over to using deterministic timing rather than real time.

* Add option to make Reporter abort on runtime scripting errors

d53c1454c0 Remove 'using namespace std' from SerialTypes.h
This unfortunately cuases a ton of flow-down changes because a lot of other
code was depending on that definition existing. This has a fairly large chance
to break builds of external plugins, considering how many internal ones it broke.

b7dee712d5 GH-887: improve GRE/ERSPAN parsing of non-IPv4/IPv6 inner payload
This changes the decapsulation logic for GRE/ERSPAN payloads to re-use
existing Layer 2 parsing logic that already handles things like 802.1Q
tags correctly before going on to process the inner IPv4/IPv6 payload.

c6f7665953 Add ability for packet sources to flag a packet's l2 or l3 checksum as valid.
This lets packet source plugins implement handling of hardware checksum offloading, if available. Setting the flags will skip the internal checksumming for either layer 2 and/or layer 3.

c5748e4494 Give real variable names to SegmentProfiler objects when defining them (bugprone-unused-raii)
The reason behind this one is that without a real variable name, the profile objects are immediately desctructed and the profiling only happens for the small window when they were valid. If the intention is to profile the method where they were defined, this doesn't actually happen.

0db61f3094 include cleanup
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):
