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.
Details:
- Renamed sandbox/c99 to sandbox/ref99. I wanted to name the sandbox so
that it would be thought of as a "reference" sandbox. I kept the "99"
to differientiate it from future reference sandboxes that may be
written in another language (such as C++).
- Updates to sandbox/ref99/README.md.
