* logging/Manager: Also pass non-null vector and set (Arne Welzel, Corelight)
Primarily to align with strings and also to keep the plugin
API the same.
* logging/Manager: Non-null strings for empty strings (Arne Welzel, Corelight)
After #4724, empty strings would result in nullptrs being stored in the
threading::Value's string_val.data field instead of a valid pointer to
an empty strings. This upsets UBSAN's nonnull check for memcpy()
[01:29:45.807] ../../src/SerializationFormat.cc:80:33: runtime error: null pointer passed as argument 2, which is declared to never be null
[01:29:45.807] /usr/include/string.h:44:28: note: nonnull attribute specified here
[01:29:45.807] #0 0x5b2e9c933a3f in zeek::detail::SerializationFormat::WriteData(void const*, unsigned long) /zeek/build/src/../../src/SerializationFormat.cc:80:5
[01:29:45.807] #1 0x5b2e9c935184 in zeek::detail::BinarySerializationFormat::Write(char const*, int, char const*) /zeek/build/src/../../src/SerializationFormat.cc:371:40
Continue to allocate the empty string for now as a fix.
* CI: Ubuntu 24.10 is eol, add Ubuntu 25.04 (Johanna Amann, Corelight)

* Add a missing header for the broker cluster serializer (Tim Wojtulewicz, Corelight)
