- There was redundance between the macro BLIS_MAX_NUM_ERR_MSGS (=200) and
the enum BLIS_ERROR_CODE_MAX (-170), while they both mean the same thing:
the maximal number of error codes/messages.
- The previous initialization of error messages at compile time ignored that
the 'bli_error_string' array still occupies useless memory due to 2D char[][]
declaration. Instead, it should be just an array of pointers, pointing at
strings in .rodata section.
- This commit does the two modifications:
* retired macros BLIS_MAX_NUM_ERR_MSGS and BLIS_MAX_ERR_MSG_LENGTH everywhere
* switch bli_error_string from char[][] to char *[] to reduce its footprint
from 40KB (200*200) to 1.3KB (170*sizeof(char*)).
(No problem to use the enum BLIS_ERROR_CODE_MAX at compile-time,
since compiler is smart enough to determine its value is 170.)
