Look like a stream synch problem, not related to cuda 7 headers or cudart
The threadfence() added doesnt changes performances, and could also
be related to the random cpu validation errors... so keep it for all.
Note: the 80-bytes variant used in skein2 doesn't seems affected.
Since linux driver 346.72, nvidia-smi allow to query gpu/mem clocks
Tested ok on the Asus Strix 970, but fails on the Gigabyte 750 Ti
system could require first persistence mode and app clock unlock :
nvidia-smi -pm 1
nvidia-smi -acp 0
supported values are displayed by
nvidia-smi -q -d SUPPORTED_CLOCKS

also add scantime per pool config option and do some pool cleanup..

do not try to restart threads from threads
Start inconditionally the stratum and longpoll threads,
these threads are just waiting a tq_push() if unused...
so add some checks to know if vars are set for the right pool

multi-pools: prepare storage/switch of credentials
for the moment:
- allow the storage of multiple -o params (and user/pass)
- allow a failover pool on connection failed
- switch to the next pool with the "seturl" api remote command
- longpoll to stratum switch (reverse to check...)
todo: mix stratum/getwork, new api commands, json config...

multipool: increase stability, but not 100% perfect
several problems fixed:
- submit to the pool set in work (source pool)
- longpoll curl timeout could be too high and could lock the switch
- mutexes cant be copied on windows (stratum global var to fully remove later)
I linked the -T timeout option to curl and tried to remove all fixed timeout values

was only made on the wallets with getmininginfo
Todo: double check for all algos/pools
tested ok on x11, lyra2, skein, skein2, zr5 stratum/longpoll
Scrypt-Jane pool net diff seems incorrect, disabled
Neoscrypt could be different also (untested, disabled)...
add params --max-temp 75, --max-rate 112.5M and --max-diff 5.0 (best for solo mining)
Note: not all the wallets are reporting the network mining difficulty and hashrate
Should give same or better than SP and klaus versions
Keep old code for older devices and skein2 compat
Linux perf: 750Ti 78MH/s and GTX 970 260MH/s
