Bug 300030: Move intrinsic width computation out of nsIFrame::Reflow and into its own methods on nsIFrame. Replace reflow reasons, types, and commands with dirty bits/notifications. Thanks to bzbarsky for almost all of the HTML form controls (mozilla/layout/forms) changes, and many others for help testing and patching. For detailed commit logs, see REFLOW_YYYYMMDD_BRANCH, where YYYYMMDD is one of 20061031, 20060830, 20060603, 20060302, 20060119, 20051011, 20050804, 20050429, 20050315, 20050111, and 20041213.
