WIP: ethminer-ProgPoW rebase - spec v0.9.2

[hackmod]

WARNING: only cuda tested.
with https://github.com/EthersocialNetwork/go-ethereum/tree/progpow-v0.9.2
(modified version of the original work by Martin)

manually rebased on top of the current master branch. + additional OpenCL fix + cuda8 fix

/share/ProgPoW/build/ethminer/ethminer --noeval -v 3 --cuda-devices 0 -U -P http://127.0.0.1:8548

I'm not try to merge this PR. this is just a (manually) rebased code.
but we can test / study and use it as a reference work to merge ProgPoW into the ethminer codebase.

ChangeLog

• CPU verifier temporally enabled (12/14)

[ddobreff]

There are already 2 PRs for progpow
integration, can’t you just work on one?

[hackmod]

yes. There are already ProgPoW PR by @MariusVanDerWijden,
and this PR is just a rebase work on top of the latest master branch.

this PR could be regarded as a reference work

@ddobreff I've just closed my PR

@hackmod Can you fix these?

Just in case of accidental merge

[hackmod]

rebased. fixed travis error

[hackmod]

binaries are available at https://github.com/hackmod/ethminer/releases/tag/v0.9.2-progpow

• only CUDA supported
• you can test it locally with --noevel option like as follow
  ethminer --noeval -v 3 --cuda-devices 0 -U -P http://127.0.0.1:8545

Thank you for all the work!
However mining currently fails with

Unexpected error CUDA error in func compileKernel at line 396 calling cuModuleLoadDataEx(&m_module, ptx, 6, jitOpt, jitOptVal) failed with error CUDA_ERROR_INVALID_PTX on CUDA device 65:00.0

PS- sorry, didn't mean to close the PR

thankyou for your feedback~

did you download binary from my repo?

for some cases, cmake detect wrong libnvrtc*so path and link different version of the nvrtc and it makes some trouble with cuModuleLoadDataEx()

[hackmod]

fixed some mistakes / CPU verifier temporary enabled for testing

[hackmod]

now OpenCL supported!

• extract compileKernel()
• compileKernel every 50 blocks

https://github.com/hackmod/ethminer/releases/tag/v0.9.2-opencl-win-1218

• binaries snapshot for testing: temporary disabled CUDA, windows binaries only.

[hackmod]

fixed epoch change issue
https://github.com/hackmod/ethminer/releases/tag/v0.9.2-opencl-win-1219

• OpenCL: fixed setArg issue after epoch change
• CUDA: fixed manual rebase mistake. (fix incompatible driver context error after epoch change)
