Bug 1457590 - Strengthen the contract around recycling HitTestingTreeNodes. r=botond This patch makes three related changes: - A non-functional change that factors a IsRecyclable function on HitTestingTreeNode. - A non-functional change that sprinkles proof-of-tree-lock arguments to a few HitTestingTreeNode functions, to ensure at compile-time that they can only be called while holding the tree lock. - A functional change that stops clearing mLayersId in HitTestingTreeNode::Destroy, so that if a node is non-recyclable, and it gets Destroy()'d while other code still has a RefPtr to it, that other code can still read the layers id off in a safe manner. These changes provide a stronger set of checks around node recycling, and allows for a safe mechanism to use a HitTestingTreeNode on the controller thread without having to lock the entire APZ tree. The mechanism is effectively a per-node lock, which will be added in the next patch. MozReview-Commit-ID: DBIjFDZJwhE

# Read the user's .mozconfig script.  We can't do this in

# expanded from configure.in, and we need to get the configure options
