- fix cuda9.1 compile (remove includ eof device_functions.hpp/ removed with cuda9.1)
- remove NVIDIA Volta gpus for MAC OSX

handle all error codes from the cuda api calls.

Makes casting more explicit.

When compiled with VS2017, the negative applied to the uint wait
time is ignored. Fixed by casting first.

- fix indention

Be more conservative with the auto suggestion.

- increase bfactor if `smx <= 6`
- limit memory for pascal < GTX1070 to 2GiB
- limt memory for pascal <= GTX1080 to 4GiB

- add macro `CUDA_CHECK_MSG_KERNEL` and `CUDA_CHECK_MSG`
- add suggestion of typicle errors can be solved

Fix nonce allocation

The "low_power_mode" option in config.txt can be set to numeral values
between 1 and 5. A value of 5 seems optimal on certain processors
with large L4 cache.

Make k unsigned.

Clean up the x-mas tree

unroll AES round by hand to help the compiler to optimize the command queue

Change the default for strided index. Th euser feedback shows that strided_index = true will give a view hashes more per second.

Allow to change the indexing used to address the hash scratchpad memory.

- add option `strided_index` for each gpu

- add option `sync_mode`
- update auto suggestion and jconf

fix #191

lauch bounds must be placed before the return type but after the template paramater

Fix for AMD GPU detection on MacOS X
On MacOS X the platform is reported as Apple, and the vendor is reported as AMD.

Fixing the compile error on MacOS X

Increase bfactor for all devices with lesser than 6 multi processors.

The max work size shown to the user was the hardware maximum but not take in account thet some kernel spwning 8 times more threads per work group than configured by the user.

- handle opencl errors to avoid unexpected behaviors
- remove code duplicatio nwithin the some method

- enforce that only host side OpenCl 1.2 functions are used if the miner is compiled with `XMR-STAK_COMPILE=generic`
- update documentation
- add CMake option `XMR-STAK_COMPILE` to windows

The lmem is still incalculably and crash the miner very often.
Increase the potential lmem usage to 16kiB to respect lmem alignments, ...

fix wrong arch comparsion

Remove whitespace lines

- removed all space indention in `*.hpp` and `*.cpp` files

* CONF_NO_TLS fix

* gpu error fix + always return to sched after pin

- check if the gpu architecture is supported by the compiled miner binary
- remove not supported gpus from the auto suggestion
- disallow the selection of a not supported gpu by hand tuning the config

Free and total memory is only evaluated on the first device.
To detect the gpu memory the gpu must be selected.

- create context on the gpu before the memory is checked
- add smx to the auto detection
- change the result code of `cuda_get_deviceinfo()`

Pass threadno up the food chain

change getName to static lc string (sorry psc)

- add type of the backend to each backend-plugin
- add `gteName` to `iBackend` to get the name of the backend

* Multi-pool first draft

* Fix wspace from new IDE

* Better TLS error message

* Fix TLS bug

* Don't put dev pool on stats + pool change-back

* bug fixes

* Error message work

* fix win build

* add per-pool nicehash setting

* Fix bugs

* rm debug msg

* Multipool guided setup

* Support TLS and Nicehash in config

* prelim jconf changes

* final multipool changes

* increase default retry_time to 30, fix mac erro

* rm debug dev pool settings

* Fix another source of connect runaway

- avoid creation of a config with zero threads or blocks
- WINDOWS: reduce the used memory for the auto suggestion by the amount of already used memory

- search for plugin in
  - working directory
  - binary directory
  - let linux search the plugins (libraries)

use `.dylib` as dynamic library file extension
