Details: - Removed four trailing spaces after "BLIS" that occurs in most files' commented-out license headers. - Added UT copyright lines to some files. (These files previously had only AMD copyright lines but were contributed to by both UT and AMD.) - In some files' copyright lines, expanded 'The University of Texas' to 'The University of Texas at Austin'. - Fixed various typos/misspellings in some license headers.
