And switch Zeek's base scripts over to using it in place of
"connection_state_remove". The difference between the two is
that "connection_state_remove" is raised for all events while
"successful_connection_remove" excludes TCP connections that were never
established (just SYN packets). There can be performance benefits
to this change for some use-cases.
There's also a new event called ``connection_successful`` and a new
``connection`` record field named "successful" to help indicate this new
property of connections.
Some Zeek script statement descriptions were exceeding the hardcoded
maximum length and also could contain tab characters which were
supposed to be reserved for use as a delimiter in the file format.
Or more generally, signatures would not work correctly for any case
where the first TCP packet seen contained payload data, regardless of
its TCP flags.

GH-654: allow table() in function &default expressions
GH-654: allow table() in record &default expressions
Fixes GH-654
* origin/topic/seth/624:
Support whitespace at end of line for config reader.
This merge fixes a failing test; it also sprinkles a few more spaces
into another test file.
The main change is that this now also works with configuration lines
that don't have a value.
This is a convenience function to make it easier to print literal byte
sequences to stdout without additional escaping like what may be added
by the default `print` statement behavior.
For example, related to GH-596, `print` currently escapes even valid
UTF-8 byte sequences and makes it difficult to output valid JSON strings
containing such.

Update COPYING.3rdparty
Use json::emplace to avoid some extra calls to operator[]
Use tessil/unordered-map instead of nlohmann/fifo-map to mitigate performance issues when logging JSON
No need to create a record introspection table each time when all
the required information can be obtained directly in the RecordVal
and RecordType objects. Besides the additional overhead, using such
a table will re-order the fields arbitrarily instead of using the
order in which they're defined.
When encrypted data was bundled within the same segment as the NewKeys
message, it wasn't not reported via a ssh_encrypted_package event as
it should have been.
- Fixed the context list padding to only be used for dialect 0x0311.
The new test case includes an example where parsing the optional
padding would fail for another dialect.
