5bf1f98200 various fixes for SM 2.1 and the benchmark 
X11+ algos and quark are not compatible for the moment

but these ones are :

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)

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

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...

ab5cc7162e refactor: create bench.cpp and algos.h 
Also enhance multi-thread benchmark synchro. with pthread barriers
