* general code cleanup
* optimized DSDOT implementation
* improved thread distribution for GEMM
* corrected IMATCOPY/OMATCOPY implementation
* fixed out-of-bounds accesses in the multithreaded xBMV/xPMV and SYMV implementations
* cmake build improvements
* pkgconfig file now contains build options
* openblas_get_config() now reports USE_OPENMP and NUM_THREADS settings used for the build
* corrections and improvements for systems with more than 64 cpus
* LAPACK code updated to 3.8.0 including later fixes
* added ReLAPACK, a recursive implementation of several LAPACK functions
* Rewrote ROTMG to handle cases that the netlib code failed to address
* Disabled (broken) multithreading code for xTRMV
