Details: - Converted most C preprocessor macros in bli_param_macro_defs.h and bli_obj_macro_defs.h to static functions. - Reshuffled some functions/macros to bli_misc_macro_defs.h and also between bli_param_macro_defs.h and bli_obj_macro_defs.h. - Changed obj_t-initializing macros in bli_type_defs.h to static functions. - Removed some old references to BLIS_TWO and BLIS_MINUS_TWO from bli_constants.h. - Whitespace changes in select files (four spaces to single tab).
