Closes#4173
This allows types to be used in expressions, but they can't be
reassigned. Note that this was meant to be a special "type expression" -
but that is unnecessary complexity.
Type expressions would allow access to the type without going through
its constant value, but the constant value is never changed, so it's
simply a few more checks if necessary when functionality gets expanded.
This way, ZAM and other code will not need updates, so the potential for
increased work in the future is probably not worth caring about.

* origin/topic/timw/merge-init-bare-sections:
Minor whitespace cleanup in init-bare.zeek
Add missing export blocks to init-bare.zeek
Merge some GLOBAL module sections in init-bare
Merge Tunnel module sections in init-bare
A command like this would segfault:
zeek -b test.zeek --debug
The issue was that `getopt_long` was using a null element to determine
what the end of the options array is. If it saw a non-null element after
`--debug` it would say it's the argument for optarg, even if it's beyond
`zeek_args.size()`. Instead, just make sure the array is
null-terminated.
* origin/topic/awelzel/lookup-connection-tweaks:
session/Manager: Emit explicit errors for FindConnection() with proto=65535
IPAddr/ConnKey: Protect from uninitialized conn_id
IPAddr/ConnKey: Promote transport to uint16_t
session/Manager: Header cleanup
We silently broke users constructing conn_id records manually and
subsequently using them with lookup_connection() or connection_exists().
This is an attempt to at least report a runtime error about the situation
so it doesn't go completely unnoticed.
Check if the non-default fields exist using HasField()
and use GetField() for proto such that it'll initialize
the default value which GetFieldAs<> doesn't do.
default
Instead of a separate bool field which is also stored in the session
table, promote the transport field to uint16_t and encode an invalid
ConnKey as transport 2**16-2
* origin/topic/johanna/gh-4061:
Update BiF-tracking, add is_event_handled
Address review comments and small updates for DNS warnings
Raise warnings when for DNS events that are not raised due to dns_skip_all_addl
If a plugin provides a write hook, the invocation for HookLogWrite() would
redo looking up the writer's name from the enum value and instantiating
a new std::string instance for every write. Avoid doing this.
There's two instances of WriterBackend::WriterInfo for a given
writer. One in Manager::WriterInfo that's accessible via
stream.writers and a copy within WriterFrontend.
Commit 78999d147d switched to use the
address of the frontend's info instance for HookLogWrite() invocations,
breaking users using the address for identification purposes.
