Details: - Fixed a bug that broke the use of 1m for dcomplex when the single- precision real and double-precision real ukernels had opposing I/O preferences (row-preferential sgemm ukernel + column-preferential dgemm ukernel, or vice versa). The fix involved adjusting the API to bli_cntx_set_ind_blkszs() so that the induced method context init function (e.g., bli_cntx_init_<subconfig>_ind()) could call that function for only one datatype at a time. This allowed the blocksize scaling (which varies depending on whether we're doing 1m_r or 1m_c) to happen on a per-datatype basis. This fixes issue #557. Thanks to Devin Matthews and RuQing Xu for helping discover and report this bug. - The aforementioned 1m fix required moving the 1m_r/1m_c logic from bli_cntx_ref.c into a new function, bli_l3_set_schemas(), which is called from each level-3 _front() function. The pack_t schemas in the cntx_t were also removed entirely, along with the associated accessor functions. This in turn required updating the trsm1m-related virtual ukernels to read the pack schema for B from the auxinfo_t struct rather than the context. This also required slight tweaks to bli_gemm_md.c. - Repositioned the logic for transposing the operation to accommodate the microkernel IO preference. This mostly only affects gemm. Thanks to Devin Matthews for his help with this. - Updated dpackm pack ukernels in the 'armsve' kernel set to avoid querying pack_t schemas from the context. - Removed the num_t dt argument from the ind_cntx_init_ft type defined in bli_gks.c. The context initialization functions for induced methods were previously passed a dt argument, but I can no longer figure out *why* they were passed this value. To reduce confusion, I've removed the dt argument (including also from the function defintion + prototype). - Commented out setting of cntx_t schemas in bli_cntx_ind_stage.c. This breaks high-leve implementations of 3m and 4m, but this is okay since those implementations will be removed very soon. - Removed some older blocks of preprocessor-disabled code. - Comment update to test_libblis.c.
