Strided index 1 is not allowed for cryptonight_v8 and monero.
In the case the dev pool is set to monero and the user tuned there settings for
an other currency the miner will crash if strided index or memChunk is not
fitting the requirement to mine monero.
This PR detects wrong configurations and will set strided index and memChunk to a valid
value but only for cryptonight_v8. The user pool settings will only be changed if monero or
cryptonight_v8 is selected.

With rocm we fighted very long with invalid shares. This is now solved with rocm 1.9 and
this tiny fix.
It is not fully clear where a memory optimization is kicking in and break the kernel `Groestl` if the variables `M` and `H` are not `volatile`.
The performance ill not change with this fix.

The fix is tested with rocm 1.9 with a VEGA64 and a RX570

Read memory in bigger chunks per thread to increase the used memory bandwith.
Use for Kepla and Fermi GPUs the old autosuggestion instead of the new settings for cryptonight_v8.

Helper functions to select the asm version based on the number of used hashes per threads and the family name of the cpu.

- use the noew cpu type functions to fix the wrong AMD family detection in `autoAdjust.hpp`
- allow to set the asm version to `auto`
- rename asm option `intel` to `intel_avx`
- rename asm option `ryzen` to `amd_avx`

- introduce monero oct 2018 fork as currency `monero`
- remove monero7
- change all dev pools
  - those miner monero7 to handle the fork to monero
  - if the dev pool can not handle the fork to monero the currency is fixed set to `monero` (we can only handle 2 different currencies for user and dev pool)
- remove guards those prevent to use the currency `monero`

I disabled a few algorithms for fatser compile and missed to re-enable them.

- restructe asm preparation function
- add double hash asm code

`uint` is unknown in windows, therefore switch to the better type `uint32_t`

In the auto adjust without hwlock the asm entry was missing

- introduce a new schema where two threads work together on one hash
- update autoadjustment
- remove an mistake where shared memory was shrinked for gpus < sm_70

apply optimizations

add cpu implementation for the final monero POW

- remove unused host function (relict from old refactoring)
- remove unused OpenCL full div function

Avoid branche differegence

- fix that shared memory for fast div is always used even if an algorithm is not using it
- optimize fast div algo
- store `division_result` (64_bit) per thread instead of shuffle around and store it as 32bit

- use optimzed div and sqrt
- reduce memory footprint

Add fast version for div and sqrt for the cuda backend

- fix code style issues
- fix spelling issue
- fix asm to support newer clang versions

- reintroduce monero7 until the POW is final
- update docs (add cryptonigh_v8)

- add special asm version for win64 and linux
- add cmake path for MSVC and other systems

- fix assembler code to pass the clang compiler
- CMake: set asm file language
- fix icc with gcc-7 compile issue with `_addcarry_u64`

Remove the asm option `auto` by `off`

If single hash is used the type of the variable to hold the intermediat sqrt value is
changed from `__m128i` to `uint64_t` as suggested by @SChernykh

- add new option to `cpu.txt` named `asm` to select the asm code version
- extent function selection method to choose assembler code for `cryptonight_v8`
- update auto adjustment to add default value for option `asm`

Add @SChernykh assembler version for ryzen and intel processors.

add option `unroll` for OpenCL to allow better tuning the main POW kernel.

Create a special pass for NVIDIA GPUs to load memory chunks first into the shared memory.

- use shared memory to exchange

implement `cryptonight_v8`

- implement cryptonight_v8
- update auto adjust to fit the special requirements of `cryptonight_v8`
- add fast math integer implementation for `sqrt`, `reciprocal`  and `division`

Add support for single hash cryptonight_v8.

- rmeove currency `monero7`
- introduce `cryptonight_v8` and `monero8`

During the initialization of the compile parameter for OpenCL it could be that the
fixed size buffer is to small. To avoid this we are now using `std::string`.
There is no problem by using `std::string` because this part of code is not perfromance critical.
