- Removed "binary" and "octet-stream" mime type detections. They don't
provide any more information than an uninitialized mime_type field
which implicitly means no magic signature matches and so the media
type is unknown to Bro.
- Slight change to "text/plain" signature. It's still not the most
accurate, which is reflected in its -20 strength value.
- The logic for adding file ids to {orig,resp}_fuids fields of
the http.log incorrectly depended on the state of
{orig,resp}_mime_types fields, so sometimes not all file ids
associated w/ the session were logged.
- Recorrected the module name to Files.
- Added Files::analyzer_name to get a more readable name for a
file analyzer.
- Improved and just overall better handled multipart mime
transfers in HTTP and SMTP. HTTP now has orig_fuids and resp_fuids
log fields since multiple "files" can be transferred with
multipart mime in a single request/response pair. SMTP has
an fuids field which has file unique IDs for all parts
transferred. FTP and IRC have a log field named fuid added
because only a single file can be transferred per irc and ftp
log line.
