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

Uninitialized memory access is UB in C/C++, fix it.

Add windows exit

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

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 settings

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()`

Print motd on console and web ui

Pass threadno up the food chain

change getName to static lc string (sorry psc)

- update usage.md
- hpdate help output

Change attribution

Added long version as a separate option

Add version to web and json

- generate define `BACKEND_TYPE` type in CMake
- fix comile because `GIT_COMMIT_HASH` is no string

Split hashrate report into backends

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

Versioning final version

Define GIT_COMMIT_HASH via cmake or git archive

* 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

Added the option to forcefully flush STDOUT, which may be useful when running the miner through a pipe instead than a shell.
If STDOUT is a shell, it's unbuffered by default.
If STDOUT is a pipe, it's buffered by default.
