memory: switch loop condition around in blas_memory_free
...
Before this commit, the "position < NUM_BUFFERS" loop condition from
blas_memory_free will be completely optimized away by GCC. This is
because the condition can only be false after undefined behavior has
already been invoked (reading past the end of an array). As a
consequence of this bug, GCC also removes the subsequent if statement
and all the code after the error label because all of it is dead.
This commit switches the loop condition around so it works as intended.

The problem is the mutex we used in blas_server. Thus, we must clear

Avoid failure on qemu guests declaring an Athlon CPU without 3dnow!
...
The present patch verifies that, on machines declaring an Athlon CPU model and
family, the 3dnow and 3dnowext feature flags are indeed present. If they are
not, it fallbacks on the most generic x86 kernel. This prevents crashes due to
illegal instruction on qemu guests with a weird configuration.

Refs #221 #246 . Fixed the overflowing stack bug in mutlithreading BLAS3.
...
When NUM_THREADS(MAX_CPU_NUNBERS) is very large ,e.g. 256.
typedef struct {
volatile BLASLONG working[MAX_CPU_NUMBER][CACHE_LINE_SIZE * DIVIDE_RATE];
} job_t;
job_t job[MAX_CPU_NUMBER];
The job array is equal 8MB.
Thus, We use malloc instead of stack allocation.

Instead of using thread 0 buffer, each thread uses its own sb buffer.
Thus, it can avoid overflowing thread 0 buffer.

add a sanity check on the detected cpu type
...
if we have 64 bit pointers we can't have a 32 bit cpu, so fall back to
the 64bit cpu fallback (prescott)
E.g. the cpu detection fails in amd qemu64 emulation (family 6 model 2)
causing it to use the uninitialized gotoblas_ATHLON

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;
}
