The basic idea here is as follows:
* Rule nodes are reference-counted, but releasing them adds them to a linked
list rather than freeing them. This allows for the reuse that motivated the
original GC scheme.
* We get rid of the marking, and instead rely on the reference count.
* Sweeping no longer requires a complicated traversal. We just pop items
off the free list until it's empty. When a child is destroyed, its parent
may go onto the free list.
* We remove special handling for the root node, and use a regular reference-counted
edge from the style set.
* The free list automatically asserts that it's empty (meaning all nodes have been
freed) in its destructor, which runs when the style set is destroyed.
* We get rid of the list of style context roots on the style set. We still need
a count though, because of the HasCachedStyleData check.
disableglobalhistory is an attribute that we support on <xul:browser> that
can be used to signal to the underlying DocShell whether or not it should
record visits in global history.
This patch adds support for this attribute by detecting it at the time
that the TabParent is bound to the browser, and then sending the presence
of the attribute to the TabChild, which then sets the state in its DocShell.

The command helpfully downloads a docker image created by a taskcluster task,
which can be helpful when trying to replicate subtle bugs that only occur
in-tree.
This also fixes a bug in hashing Dockerfile directories, where the full
pathname was taken into account. While this pathname is consistent from
decision task to decision task, it is not consistent with developers' home
directories. This change omits the directory prefix, which will cause a
one-time shift in all directory hashes.

Also, remove no longer used code and update comments to properly reflect the current algorithms used.

20MB appears to work, but just to be safe until we get confirmation from YouTube on what is a safe value to use.
