ed4927fcd0 quark/x11: set signed int hashPosition vars to off_t 
groestl (and keccak?) seems faster with 64bit vars (off_t or int64_t)...

0224d4705e skein: fix wrong hashes seen on x11 with cuda 7 
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.

38e6672d70 Allow test of SM 2.1/3.0 binaries on newer cards 
Implementation based on klausT work.. a bit different

This code must be placed in a common .cu file,
cuda.cpp is not compiled with nvcc and doesnt allow cuda code...

2585e10814 keccak uint2 optimisation for SM>3.0 (x11 +40KH/s) 
based on djm34 keccak 256-bit changes, and keep SM3.0 compat

affect most other algos too (quark, nist5, x13...)

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...
