b02f22a667 Change SSL and X.509 logging format
This commit changes the SSL and X.509 logging formats to something that,
hopefully, slowly approaches what they will look like in the future.

X.509 log is not yet deduplicated; this will come in the future.

This commit introduces two new options, which determine if certificate
issuers and subjects are still logged in ssl.log. The default is to have
the host subject/issuer logged, but to remove client-certificate
information. Client-certificates are not a typically used feature
nowadays.

64ab1bbd47 Enable OCSP logging by default.
In the past I thought that this is not super interesting. However, it
turns out that this can actually contain a slew of interresting
information - like operating systems querying for the revocation of
software signing certificates, e.g.

So - let's just enable this as a default log for the future.

011ac442a1 Remove the Stepping Stone analyzer
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.

This patch adds the ability to decap Geneve packets to process the inner
payload. The structure of the analyzer borrows heavily from the VXLAN
analyzer.

4ce3bf3cd2 Remove deprecated log filter predicates for 4.1
Update the logging framework tests: since hooks operate
by name, they cannot be anonymous. I'm also dropping the &optional
attribute from the status field, since here know that the values are
actually defined, and access to an optional status field should
normally be guarded by the existence test operator.

Also includes baseline update for plugins.hooks, which picks up the
fact that the pred record field is now gone.

05cf511f18 GH-1119: add base/protcols/conn/removal-hooks.zeek
This adds two new functions: `Conn::register_removal_hook()` and
`Conn::unregister_removal_hook()` for registering a hook function to be
called back during `connection_state_remove`.  The benefit of using hook
callback approach is better scalability: the overhead of unrelated
protocols having to dispatch no-op `connection_state_remove` handlers is
avoided.

613b27eec7 GH-1080: Rename conflicting NetControl::DROP enum definitions
``NetControl::DROP`` had 3 conflicting definitions that could potentially
be used incorrectly without any warnings or type-checking errors.
Such enum redefinition conflicts are now caught and treated as errors,
so the ``NetControl::DROP`` enums had to be renamed:

* The use as enum of type ``Log::ID`` is renamed to ``NetControl::DROP_LOG``

* The use as enum of type ``NetControl::CatchReleaseInfo`` is renamed to
  ``NetControl::DROP_REQUESTED``

* The use as enum of type ``NetControl::RuleType`` is unchanged and still
  named ``NetControl::DROP``

a06ef66edc Add Log::rotation_format_func and Log::default_rotation_dir options
These may be redefined to customize log rotation path prefixes,
including use of a directory.  File extensions are still up to
individual log writers to add themselves during the actual rotation.

These new also allow for some simplication to the default
ASCII postprocessor function: it eliminates the need for it doing an
extra/awkward rename() operation that only changes the timestamp format.

This also teaches the supervisor framework to use these new options
to rotate ascii logs into a log-queue/ directory with a specific
file name format (intended for an external archiver process to
monitor separately).

5b4313b593 Deprecate Val(double, TypeTag) ctor, add TimeVal/DoubleVal subclasses
This also updates all usages of the deprecated Val ctor to use
either IntervalVal, TimeVal, or DoubleVal ctors.  The reason for
doing away with the old constructor is that using it with TYPE_INTERVAL
isn't strictly correct since there exists a more specific subclass,
IntervalVal, with overriden ValDescribe() method that ought to be used
to print such values in a more descriptive way.

3bce313b12 Switch file UID hashing from md5 to highwayhash.
This commit switches UID hashing from md5 to a highway hash. It also
moves the salt value out of the file plugin - and makes it
installation-specific instead - it is moved to the global namespace.

There now are digest hash functions to make "static"
installation-specific hashes that are stable over workers available to
everyone; hashes can be 64, 128 or 256 bits in size.

Due to the fact that we switch the file hashing algorithm, all file
hashes change.

The underlyigng algorithm that is used for hashing is highwayhash-128,
which is significantly faster than md5.

bc546634d1 Switch most internal md5 calls to digest calls.
The places that used md5 basically already used it as a digest
algorithm. Switching to a digest just means that the internal values
used to not change between runs - which is actually wanted in these
cases.

This commit also removes our special cmake subdirectory. We don't expose
highwayhash in headers anymore - so we can just treat it as an internal
implementation choice that is not directly exposed to plugins.

5032993b94 GH-854: provide access to original HTTP/MIME header names
The "http_header" event now has an "original_name" parameter that allows
access to the original header name (the "name" parameter reamins the
same as before: it's the uppercased header name).

The "mime_header_rec" record type now also includes an "original_name"
field to similarly provide access to original header name in the
following events: "http_all_headers", "mime_one_header", and
"mime_all_headers".
