also known as "Thor's Riddle"... yes sure ;)
Credits to ocminer who found and "implemented" it.
Note: tested "ok" on x64 and CUDA 6.5 x86, not on 7.5 and 8.0 x86
PS: Don't have the time for a more proper CUDA implementation of Streebog
made for linux and require libpci-dev (optional)
if libpci is not installed, card's vendor names are not handled...
Note: only a few vendor names were added, common GeForce vendors.

Since linux driver 346.72, nvidia-smi allow to query gpu/mem clocks
Tested ok on the Asus Strix 970, but fails on the Gigabyte 750 Ti
system could require first persistence mode and app clock unlock :
nvidia-smi -pm 1
nvidia-smi -acp 0
supported values are displayed by
nvidia-smi -q -d SUPPORTED_CLOCKS

only allowed if --api-remote parameter or config key is set
and fix possible problem with urls containing user:password@

heavy: reduce by 256 threads default intensity to all -i 20
cuda: put static thread init bools outside the code (made once)
api: fix nvml header to build without
There was a different behavior on linux and visual studio
That was making it hard to link functions correctly
That remove some ifdef / extern "C" requirements
note about x86 releases, x86 nvml.dll is not installed on Windows x64!
Based on mwhite73 <marvin.white@gmail.com> implementation
Linked to the api system
Also fix Makefile to support standard c++ files
This prevent nvcc use without device code

Unlike other hash algos, blake256 compute the hash
with blocks of 64 bytes.
We can do the first part on the cpu, only the 4 last int32
are computed on gpu (including the tested nonce)
Previous method was also using this kind of cache with a crc.
Blake Hash Speed: +5%
based on klaus commits, will increase a bit speed of most algos
PS: main increase is due to the register count tuning in Makefile
and for skein512 on linux, its the ROTL64
but almost no changes on X11 : 2648MH/s vs 2630 before
