Fixed reference to wrong field name.
Added documentation of a function arg.
Added a couple references to other parts of the documentation.
Explained how not specifying extraction filename results in automatic
filename generation.
Several other minor clarifications.
This cleans up internals of how analyzer instances get identified by the
tag plus any args given to it and doesn't change script code a user
would write.
- Fix examples/references in the file analysis how-to/usage doc.
- Add Broxygen-generated docs for file analyzer plugins.
- Break FTP::Info type declaration out in to its own file to get
rid of some circular dependencies (between s/b/p/ftp/main and
s/b/p/ftp/utils).
- Several places were just using old variable names or not loading
scripts correctly after they'd been renamed/moved.
- Revert/adjust a change in how HTTP file handles are generated that
broke partial content responses.
- Turn some libmagic builtin checks back on; seems some are actually
useful (e.g. text detection seems to be a builtin). The rule going
forward probably will be only to turn off a builtin if we confirm it
causes issues.
- Removed some tests that are redundant or not necessary anymore because
the generic file analysis tests cover them.
- A couple FTP tests still fail that I think need an actual solution via
script changes.
- 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.
