This commit removed functions/events that have been deprecated in Bro
2.6. It also removes the detection code that checks if the old
communication framework is used (since all the functions that are
checked were removed).
Addresses parts of GH-243
Base64Converter now uses a connection directly, instead of an analyzer
redirecting to the underlying connection for reporting to Weird. The new
built-in functions en-/decode_base64_intern make use of this to send
encoding-errors to Weird instead of Reporter.
According to the documentation, using the empty string as alphabet in
the built-in functions, will use the default alphabet. Therefore the
built-in functions can now use default arguments and
en-/decode_base64_custom is deprecated.
The tests have been updated accordingly.
