e50556b637 various changes, cleanup for the release 
small fixes to handle better the multi thread per gpu

explicitly report than quark is not compatible with SM 2.1 (compact shuffle)

d3e2088398 basic pool algo switch (without free barrier) 
not really proper but should works for 2 "small" algos.

just put the "algo" param in each pools config

113e22de2e blake: prevent empty scan ranges with multiple gpus 
in some cases, an empty scan range was possible in benchmark..

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...

e12d666d36 pool switch: add thr_id param to handle a future barrier 
Switching to a pool with a different algo will require a barrier
to free ressources, like what was made in the global benchmark.

add also the algo in pool structure...

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...

9dfa757dc7 warn on cuda errors + various small changes 
The full benchmark can now be launched with "ccminer --benchmark"

add a new helper function which log a warning with last cuda error
(not shown with the quiet option) : CUDA_LOG_ERROR();
it can be used where miner.h is included (.c/.cpp/.cu)

fix x14 (in ccminer.cpp), a break was missing in switch..case

8fbfe2cfda add gpulog() function helper, simple and multi-threads 
when using multiple cpu threads per gpu, use the T prefix, ex:

[2015-10-11 09:52:49] GPU #0: app clocks set to P0 (3600/1228)
 vs
[2015-10-11 09:52:51] GPU T0: MSI GTX 960, 5953.35 kH/s

Only thr_id is required, the function take care of the dev id

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

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...
