355b835ae0 benchmark: enhance the mem leak detection 
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)

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...

fc84c719e9 lyra2: improve cuda implementation (part 1, SM5+) 
based on the new djm34 method, 2x faster than first version

cleaned and tuned for the GTX 750/960 (linux / cuda 6.5)

d195f2e8a2 intensity: do not reduce throughput before init 
Else the memory allocated could be less than required later

btw, use the new "cuda" function to apply intensity/throughput

c6dcc5e5cf benchmark: show mem and default throughput in results 
and prepare a new function to get the default intensity

also, take care of multiple threads per gpu...

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...

49a73971c4 Enhance stale work detection + throughput fixes 
seems to resolve solo mining lock on share.
export also computed solo work diff in api (not perfect)

In high rate algos, throughput should be unsigned...
This fixes keccak, blake and doom problems

And change terminal color of debug lines, to be selectable in putty,
color code is not supported in windows but selection is ok there.

Only usable on the test pool until 16 december 2014!
