These are no longer loaded by default due to the performance impact they
cause simply by being loaded (they have event handlers for commonly
generated events) and they aren't generally useful enough to justify it.
- 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.
- Moved the Notice::notice event and Notice::policy table to both be hooks.
- Renamed the old Notice::policy to Notice::policy_table and documented it as deprecated.
- The table tracking notice suppressions is now done with a table
attribute instead of "manually" with scheduled events.
- The $suppress_for field can be set within PolicyItem's now too to
affect the suppression interval through the notice policy.
- The test needed to append the second notice the event queue so that
the notice would be suppressed correctly.
- Setting $suppress_for manually in apply_policy since it doesn't pick
up the &default when directly creating the record inside the NOTICE call.
