Added f2c'ed Givens rotation wrappers.

Browse Source 
Details:
- Retired (for now) existing ?rot*() BLAS compatibility wrappers to 'attic'
  along with other wrappers for which no BLIS implementation exists.
- Added f2c-generated codes for applicable datatype flavors of rot, rotg,
  rotm, and rotmg operations.
