clarify how old code may use the new error_table[] array

Browse Source 
Code that used the old array error_table[] of error message strings
such as:

    #include "calcerr.h"

    char *msg;	/* calc computation error message */

    msg = error_table[errnum - E__BASE];

where errnum is the calc computation error code
E__BASE <= errnum <= E__HIGHEST, may now use:

    #include "errtbl.h"
    #include "errsym.h"

    char *msg;	/* calc computation error message */

    msg = error_table[errnum - E__BASE].errmsg;
