2d72f00ccf Have ContentBox(es)Queries consult the flow tree 
Instead of looking at the display tree, have ContentBox(es)Query consult
the flow tree. This allow optimizing away parts of the display tree
later. To do this we need to be more careful about how we send reflow
requests, only querying the flow tree when possible.

Fixes #3790.

a208463b62 layout: Employ a persistent list data structure to avoid copying floats 
all the time.

Improves performance on the maze solver significantly since this was
basically O(n^2) before.

08fc7c2795 layout: Make incremental reflow more fine-grained by introducing "reflow

f5ad89f927 auto merge of #3747 : mrobinson/servo/validate-display-list, r=pcwalton 
When this option is enabled, the layout task will print an error when
display list items draw outside their owning Flow's position rect. This
will make it easier to detect layout errors before they break rendering.

This is a command-line option for the moment, because we violate this
rule quite a bit still. Once all bugs causing this are fixed, we can be
more aggressive about enabling the option.

If we start collecting too many debugging options in the servo
executable we could opt to organize them into a single option.
