a43205a84f decred: multiple nonces code cleanup 
The double loop is not useful, and prefer the __thread attribute
to enhance the code readability (remove the 2D host arrays).

squashed: return to host 2D array to allow the free

9eead77027 diff: show by default, rework shares diff storage 
This will allow later more gpu candidates.

Note: This is an unfinished work, we keep the previous behavior for now
To finish this, all algos solutions should be migrated and submitted nonces attributes stored.
Its required to handle the different share diff per nonce and fix the possible solved count error (if 1/2 nonces is solved).

c643b3b900 decred: and even faster implementation by Alexis 
optimized for the 9xx and more recent, same results on the 750 Ti
+ restore second nonce support not present in nicehash published version

Better on linux at least...

61ff92b5b4 never interrupt global benchmark with found nonces 
fix some algo weird hashrates (like blake)
and reset device between algos, for better accuracy

but this reset doesnt seems enough to bench all algos correctly...

to test on linux, could be a driver issue...

heavy: fix first alloc and indent with tabs...

4868c412b0 windows: add support for SM 2.1, drop SM 3.5 (x86) 
Mostly to do compatibilty tests, SM 2.1 support is very limited

SM 3.0 code should run on SM 3.5 (only a few cards use this arch)

As i can't test SM 3.5, its best to let users do their own tests...

c2214091ae benchmark: free last memory leaks on algo switch 
remains my original lyra2 implementation to fix... (cuda_lyra2.cu)

I guess some kind of memory overflow force the driver to allocate
memory... but was unable to free it without device reset.

4e1e03b891 benchmark: store all algos results + cuda fixes 
Note: lyra2, lyra2v2 and script seems to have problems
to coexist with other algos... to run after some of them...

moved lyra2 first and skip scrypt/jane for the moment...

Only stored in memory for now.. to display a table after the bench

ccminer -a auto --benchmark

Results may be exported later to a json file...
