- Enable manager to associate analyzers with a MIME type. With that,
one can now say enable all analyzers for, e.g., "image/gif". This is
exposed to script-land as
Files::add_analyzers_for_mime_type(f: fa_file, mtype: string)
For MIME types identified via libmagic, this happens automatically
(via the file_new() handler in files/main.bro).
- Extend the analyzer API to better match that of protocol analyzers:
- Adding unique analyzer IDs so that we can refer to instances
from script-land.
- Adding subtypes to Components so that a single analyzer
implementation can support different types of analyzers
internally.
- Add an analyzer method SetTag() that allows to set the tag after
construction.
- Adding Init() and Done() methods for consistency with what other
classes offer.
- Add debug logging to the file_analysis stream.
TODO: test cases missing for the new script-land functionality.
Made some class templates for code that seemed duplicated between
file/protocol tags and managers. Seems like it helps a bit and
hopefully can be also be used to transition other things that have
enum value "tags" (e.g. logging writers, input readers) to the
plugin system.
