Merge branch 'bulldozer' into develop
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.
Fixed the overflowing bug in single thread cholesky factorization.
Refs #174. Return sb pointer when OpenMP or Windows.
In OpenMP threading, preallocate the thread buffer instead of allocating the buffer every time. This patch improved the performance slightly.
Improved the print when OS don't support AVX.
Updated the doc for 0.2.6 version.
