import and keep my code for older archs, like skein 64
reduce the gap between our versions...
+150kH x11 GTX 960 / +30kH 750Ti
+900kH quark GTX 960 / +230kH 750Ti
Quark and S3 are now a bit faster (+1 %)
x11 get +0.6 % (+20kH/s on a 750ti, +30kH on a 960)
80 bytes implementation to do/test ... (skein/skein2)
but keep my previous version for older devices...
reduce "false" warnings, and ignore unrelated/small ones <= 1 MB
On windows the gpu memory can be allocated by other processes
+ some cleanup in algos... (free/gpulog)
Added to most algos, checkhash function scans a big range
and can find multiple nonces at once if the difficulty is low.
Stop ignoring them, submit second one if found...
Clean the draft code for rc=2 implemented for blake and pentablake
btw... fix the reduced displayed hashrate when a nonce is found...

Tested on x11 which find sometimes 3 nonces in one call,
actually they are ignored because only the biggest was kept...
This commit doesnt fix that, but will allow to enhance shares rate later...
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
Sample with -i 18.5
Adding 131072 threads to intensity 18, 393216 cuda threads
And with -i 19.5
Adding 262144 threads to intensity 19, 786432 cuda threads
Small echo rewrite. +10KHASH on the 650(compute 3.0)
tpruvot: add Linux Makefile - Force to 80 registers (else -30KH/s)
Note : the hashrate seems more constant with this change
Was maybe my fault, but the benchmark mode was
always recomputing from nonce 0.
Also fix blake if -d 1 is used (one thread but second gpu)
stats: do not use thread id as key, prefer gpu id...
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
Project was updated for VS2013 and CUDA SDK 6.5
add also a --cputest function to dump cpu hash results
TODO: x15 is not fully functional, but first loop seems ok
