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.

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...

Enhance stale work detection + throughput fixes

seems to resolve solo mining lock on share.
export also computed solo work diff in api (not perfect)

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.
