Details: - Changed the way bli_type_defs.h defines integer types so that dim_t, inc_t, doff_t, etc. are all defined in terms of gint_t (general signed integer) or guint_t (general unsigned integer). - Renamed Fortran types fchar and fint to f77_char and f77_int. - Define f77_int as int64_t if a new configuration variable, BLIS_ENABLE_BLIS2BLAS_INT64, is defined, and int32_t otherwise. These types are defined in stdint.h, which is now included in blis.h. - Renamed "complex" type in f2c files to "singlecomplex" and typedef'ed in terms of scomplex. - Renamed "char" type in f2c files to "character" and typedef'ed in terms of char. - Updated bla_amax() wrappers so that the return type is defined directly as f77_int, rather than letting the prototype-generating macro decide the type. This was the only use of GENTFUNC2I/GENTPROT2I-related macros, so I removed them. Also, changed the body of the wrapper so that a gint_t is passed into abmaxv, which is THEN typecast to an f77_int before returning the value. - Updated f2c code that accessed .r and .i fields of complex and doublecomplex types so that they use .real and .imag instead (now that we are using scomplex and dcomplex).
