Support intrinsic values for height, min-height and max-height

As specified in http://dev.w3.org/csswg/css-sizing/

The changes here fall in three categories:
- Change RenderBox to pass the content height through to
  computeLogicalHeight and related functions, which needs it to resolve
  max-content, et. al.
- Make the callers pass the content height to this function. Some
  callers pass logicalHeight() (adjusted for border/padding) - this
  works because if logicalHeight is not the content height, then it is
  the height we ended up using, so the constrain* functions will just
  constrain to that value again
- Changes to CSS parsing to accept the values for heights, not just
  widths.
