[Intent to Close Bugzilla Component] Toolkit::Security

After consulting with dveditz, we're moving the bugzilla.mozilla.org
component Toolkit::Security to Toolkit::Graveyard. That means no more bugs
will be able be filed against the component.

We're going to fast-track closing this out because there are unresolved
bugs in it, and it never represented a feature or specific code part of the
product where closing the bug component implies abandoning the code itself.

Toolkit::Security was a magnet for misfiled bugs that were actually
'security flaws in toolkit' that should have been filed against the
specific Toolkit feature with the flaw. That kept bugs away from
developers who weren't aware of them unless there was additional triage.

Again, since there are no open bugs, and no explicitly associated code,
we'll move this tomorrow, Wednesday the 29th.

Thank you,

Emma Humphries
