OpenCl kernel using a larger work group size than configured by the
user to increase the occupancy. Depending on the algorithm and device
the size is limited.

This PR fixes that the user was able to select a invalid work group size.

OpencL: fix cn_gpu

fix missing algorithm name

CUDA. fix static in global kernel

If comp_mode is used the code will not compile.

- fix compile issue
- fix wrong conditions to handle `comp_mode`

During the implementation of `cryptonight_gpu` we missed to add the name
of the algorithm to jpsock.

- add function to translate an algorithm into a name.

Remove `static constexpr` within the global kernel. This is not
supported by all CUDA versions.

update version to 2.8.0

update documentation

coin cleanup

- remove driver warning
- add link to supported card y the ROCm driver

OpenCL: fix Blake hashing

- rename `Intense` to `Lethean`
- remove `masari` and `stellite`, both hase forked to a currently
unsupported algorithm

Windows driver creates wrong code if unroll is used.

OpenCL: fix work size message

CUDA: optimze cn_gpu auto suggestion

OpenCL: use algorithm names instead of number

add ryo algorithm fork

cuda: optimize cn-gpu

Fix message with the maximal allowed worksize if cryptonight_gpu is
used.

optimize the algorithm for cryptonight_gpu autosuggestion

switch with block 6 to cryptonigh_gpu

 - use precomuted indicies within the loop
 - `cn_explode_gpu` use all threads to load the state

Use the algorithm names from `cryptonight.hpp` instead if number within the OpenCL kernel.

fix cuda 10

- fix race condition during shared memory access
- optimize memory access

Implement CN-GPU Proof-of-Work Algo

- fix broken trutle coin
- fix non cn_gpu algorithms

refactor POW selection algorithm

Avoid that we do multiple lookups to `std::map` to find the OpenCL
kernel binaries.

- add helper method `GetAllAlgorithms()` to get all active POW
algorithms
- select max scratchpad memory size based on the dev pool and user
algorithms

In the current implementation the POW algorithm in dev pool section of a
currency will not be taken into account during the binary creation.
This PR changes the behavior and allow to create binaries for more than two POW algorihms.
