b5d30b390d Fix build issues with bfloat16 
This patch fixes compilation errors due to recent renaming from SH to SB
with BUILD_BFLOAT16.

deaeb6c5b8 Add bfloat16 based dot and conversion with single/double 
1. Added bfloat16 based dot as new API: shdot
2. Implemented generic kernel and cooperlake-specific (AVX512-BF16) kernel for shdot
3. Added 4 conversion APIs for bfloat16 data type <=> single/double: shstobf16 shdtobf16 sbf16tos dbf16tod
     shstobf16 -- convert single float array to bfloat16 array
     shdtobf16 -- convert double float array to bfloat16 array
     sbf16tos  -- convert bfloat16 array to single float array
     dbf16tod  -- convert bfloat16 array to double float array
4. Implemented generic kernels for all 4 conversion APIs, and cooperlake-specific kernel for shstobf16 and shdtobf16
5. Update level1 thread facilitate functions and macros to support multi-threading for these new APIs
6. Fix Cooperlake platform detection/specify issue when under dynamic-arch building
7. Change the typedef of bfloat16 from unsigned short to more strict uint16_t

875d520ccf Refs #193. cblas: move #include out of extern "C" block. 
Standard headers may contain C++ templates which are not permitted inside an
extern "C" block. This might be the case when we include <complex.h>.

200e4acf15 cblas: typedef enums for improved compatibility with Intel MKL. 
Netlib style:
    enum CBLAS_XYZ {X=1, Y=2, Z=3};

Intel MKL style:
    typedef enum {X=1, Y=2, Z=3} CBLAS_XYZ;

With this hybrid style, code written in the latter form won't need any
modifications to be built with OpenBLAS.  This change should not affect existing
code, although a warning may be emitted for C code which does the following
(does not occur with C++):
    typedef enum CBLAS_XYZ CBLAS_XYZ;
    warning: redefinition of typedef 'CBLAS_XYZ' [-pedantic]

bdf8d9411e Refs #163. Obtain the build configure on runtime. 
openblas_get_config function returns the configure string.
So far, it supports USE64BITINT, NO_CBLAS, NO_LAPACK, NO_LAPACKE,
DYNAMIC_ARCH, NO_AFFINITY.

Example:
 #include <stdio.h>
extern char * openblas_get_config();
void main()
{
  printf("%s\n",openblas_get_config());
  return;
}
