This patch provides some of the groundwork for column spans greater than 1. It implements the column-span CSS property as well as the corresponding colspan attribute; although the former is not well-specified outside of CSS multi-column layout, INTRINSIC refers to it. Although width is distributed to spanning columns, they do not yet contribute minimum and preferred widths; this will be implemented in a follow-up. The parsing for the legacy bgcolor and border attributes is implemented according to the WHATWG HTML specification. Additionally, this patch cleans up some miscellaneous formatting issues, refactors layout/css somewhat to eliminate needless levels of indirection, and cleans up the handling of table rowgroups.
