Replaced mutex in constellation logging by a reentrant mutex.
<!-- Please describe your changes on the following line: -->
The double-panic in #12553 may be caused by using a non-reentrant lock, which panics on reetry. This PR adds a reentrant lock type (slightly annoyingly, the implementation in std isn't exported) and uses it for logging. cc @jdm

stylo: Improve restyling performance
This commit adds hooks to the Servo style traversal to avoid traversing all the
DOM for every restyle. Additionally it changes the behavior of the dirty flag to
be propagated top down, to prevent extra overhead when an element is dirtied.
This commit doesn't aim to change the behavior on Servo just yet, since Servo does extra job when dirtying the node related with DOM revision counters that might be necessary.
CC @asajeffrey for the DOM revision counters stuff. When a node is dirty, do all its descendants really need to increment the revision counter, or is this an unintended effect? My intuition is that this is hurting performance quite a lot for servo.

This is what was making me hit the new test failures. So turns out that when the
DOMContentLoaded event is fired we fired no messages to the constellation, but
we fired the DOMLoad message from the DocumentProgressHandler, effectively after
having dispatched the Load message from script thread.
This also fixes the possibility of a subframe navigation not blocking the load
event of the parent document, for example.
Fix backward navigation
make use of history iterator
Add frame iterator
add different back logic
cleanup navigation_info
Add extra explanation for iter logic
Remove forward history on full frame tree
Rename navigation to traversal where appropriate
check full tree for can go back/forward
simplify frame iter logic
remove FrameIterator
cleanup history iter
reduce amount of vec allocations
removed extra parenthesis
Remove history iterator
cleanup after rebasing
avoid recursive vec allocation
remove full_frame_tree
remove_forward_history_in_frame_tree -> clear_joint_session_future
Removed panic channel, replaced by integrated logging and issue reporting
<!-- Please describe your changes on the following line: -->
Remove the previous ad hoc panic channel, replace it by an integrated logging and panicking mechanism, including crash reporting. All thread panics are now reported, not just content threads.

Implement non-visible pipeline and iframe visibility methods
This addresses #9566 and a good part of #9751, specifically:
* Pipeline has a notion of visibility
* IFrame setVisible/getVisible interface with IFrame's pipeline visibility
* IFrame mozbrowservisibilitychange responds to changes in visibility
* Pipeline visibility is used to limit animations (requestAnimationFrame does not tick animations when hidden) and to increase timer intervals (currently set to a minimum of 1 second while hidden)
Absent for now are any changes to the Document API and general implementation of the Page Visibility API, since the more interesting parts require knowledge of whether the user agent is minimized, OS screen locked, etc.
