Ping #19116

We can't set whatever key_bin points to when key_bin is NULL.
Fail and return -1 on a null key_bin earlier, warning if assertions
are enabled because this is a programming error.

Remove init of proto, header field, expert info and subtree variables.
This will reduces the binary size by approximate 1266320 bytes due to
using .bss to zero-initialize the fields.
The conversion is done using the tools/convert-proto-init.py script.

If the short_length field is set and we know the length,
call set_actual_length so that the FCS calculation is done
in the previous ethertype dissector and thus over the entire
frame (and in the normal field). This helps when FCS detection
is by heuristic; before the FCS was just placed in a macsec
padding field (as still happens with non short length MACsec
frames.)
Also add the ICV as appendix to the MACsec proto tree.

Changes several calls of `create_dissector_handle()` to instead call
`register_dissector()` with a name for the dissector.
This should handle all dissectors in `epan/` from `packet-j*` to
`packet-o*`.
This change allows affected dissectors to be findable by calls to
`find_dissector()`. In turn, this opens up more command-line use for
these protocols, including fuzzshark and rawshark, as well as lua use
via `Dissector.get()`.
Where needed, move the call from the protocol handoff function to the
protocol register function, save the result in a static variable,
and use that variable in the handoff function.
There were some calls to `create_dissector_handle()` or
`register_dissector()` which passed `-1` as the protocol argument. When
I saw those I corrected them to pass the actual `proto_foo` identifier
instead.
Partially addresses #5612

This patch fixes some bugs that occur with padded Ethernet frames and
frames, when a Ethernet FCS is present. In the past that lead to wrong
detection of the ICV by the Ethernet dissector (trailer).
Such errors did occur for example with frames that were padded and
MACsec was added later; thus, being bigger than expected for the
heuristics in the packet-eth.c: "pinfo->fd->pkt_len >= 60 ..."

The static arrays are supposed to be arrays of const pointers to int,
not arrays of non-const pointers to const int.
Fixing that means some bugs (scribbling on what's *supposed* to be a
const array) will be caught (see packet-ieee80211-radiotap.c for
examples, the first of which inspired this change and the second of
which was discovered while testing compiles with this change), and
removes the need for some annoying casts.
Also make some of those arrays static while we're at it.
Update documentation and dissector-generator tools.

This saves many dissectors the need to find the data dissector and store a handle to it.
There were also some that were finding it, but not using it.
For others this was the only reason for their handoff function, so it could be eliminated.

Some of the ASN.1 dissectors still generate a new_create_dissector_handle from the tool itself, so leave those for now.

Specifically:
- Set packet.h to be the first wireshark #include after
config.h and "system" #includes.
packet.h added as an #include in some cases when missing.
- Remove some #includes included (directly/indirectly) in
packet.h. E.g., glib.h.
(Done only for those files including packet.h).
- As needed, move "system" #includes to be after config.h and
before wireshark #includes.
- Rework various #include file specifications for consistency.
- Misc.
