- While updating, I did some further work on the branch. - New function in the base/utils/files for extracting filenames from content-dispositions. - New script for entity excerpt extraction if you aren't interested in full extraction. The data goes a log field too. - Some renaming and reorganization of types. - Updated tests to work with new code. * origin/topic/jsiwek/smtp-refactor: Make the doc.coverage test happy. SMTP script refactor. (addresses #509) Conflicts: doc/scripts/DocSourcesList.cmake policy/protocols/smtp/__load__.bro policy/protocols/smtp/base/__load__.bro
