Fixed in/it/on/otcopy names.

Added loop to build objects with different KERNEL defines.

This will generate obj files for SINGLE/DOUBLE/COMPLEX/DOUBLE COMPLEX.

It sets DBLAS_OBJS directly to save a bunch of list appending in the
CMakeLists.txt files.

Added some kernel/L3 objects.

Added some kernel and driver/others objects.

Allow to do gemv and ger buffer allocation on the stack

ger and gemv call blas_memory_alloc/free which in their turn
call blas_lock. blas_lock create thread contention when matrices
are small and the number of thread is high enough. We avoid
call blas_memory_alloc by replacing it with stack allocation.
This can be enabled with:
make -DMAX_STACK_ALLOC=2048
The given size (in byte) must be high enough to avoid thread contention
and small enough to avoid stack overflow.

Fix #478

Reported by Julia project. JuliaLang/julia#9084

Optimizations for APM's xgene-1 (aarch64).

1) general system updates to support armv8 better.  Make all did not work, one needed to supply TARGET=ARMV8.
2) sgem 4x4 kernel in assembler using SIMD, and configuration changes to use it.
3) strmm 4x4 kernel in C.  Since the sgem kernel does 4x4, the trmm kernel must also do 4xN.
