Refs #174 . Fixed the overflowing buffer bug of multithreading hbmv and sbmv.
Instead of using thread 0 buffer, each thread uses its own sb buffer.
Thus, it can avoid overflowing thread 0 buffer.

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]
