update windoes compile guide

Point to new xmr-stak-dep precompiled binaries if CUDA9 is used.

fix windows compile documentation

fix broken windows compile with v140

- add copy of openssl libs to appvoyer CI tests
- update windows compile documentation

add microhttpd libs explicit to `xmr-stak-c`

Update docs

fix max work size shown to user

rename to make it clearer that this is a linux binary

handle OpenCL errors

fix OpenCL compatibility

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

Fix GPU result crash

Fix gpu result crash

fix wrong cuda binary arch detection

fix nvidia auto suggestion

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

fix aeon dev pool

- fix aeon dev pool settings

Fix cases where positive feedback was still occurring.

remove space indention with tabs

Remove whitespace lines

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

Network extensions

forbid PR to master branch

- forbid PR to master if not from our reposetory and named `dev` or `release-*`
- do not check forks

check gpu architecture 

AMD: increase memory pool

fix wrong memory detection

* 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()`
