Details: - Textually replaced nearly all non-comment instances of bool_t with the C99 bool type. A few remaining instances, such as those in the files bli_herk_x_ker_var2.c, bli_trmm_xx_ker_var2.c, and bli_trsm_xx_ker_var2.c, were promoted to dim_t since they were being used not for boolean purposes but to index into an array. - This commit constitutes the third phase of a transition toward using C99's bool instead of bool_t, which was raised in issue #420. The first phase, which cleaned up various typecasts in preparation for using bool as the basis for bool_t (instead of gint_t), was implemented by commita69a4d7. The second phase, which redefined the bool_t typedef in terms of bool (from gint_t), was implemented by commit2c554c2.
