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)

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

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

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

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...

c3bdb623e8 Check and submit multiple nonces in one loop 
Added to most algos, checkhash function scans a big range
and can find multiple nonces at once if the difficulty is low.

Stop ignoring them, submit second one if found...

Clean the draft code for rc=2 implemented for blake and pentablake

btw... fix the reduced displayed hashrate when a nonce is found...

f0d91ab8a6 Luffa and simd merged to one kernal.

tpruvot: add Linux Makefile - Force to 80 registers (else -30KH/s)

438308b3a2 Rework benchmark mode and min/max range 
Was maybe my fault, but the benchmark mode was
always recomputing from nonce 0.

Also fix blake if -d 1 is used (one thread but second gpu)

stats: do not use thread id as key, prefer gpu id...
