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.

Add an option to brute force intensity settings and lock in at the intensity with the highest hashrate. - update decumentation of the `interleave` option to mention the side effect with `auto-tune` - disable `interleave` auto adjustment if `auto-tune` is enabled - jconf: add `auto-tune` as optional option

Disable compatibility mode if intensity is a multiple of worksize. In that case enabled compaibility mode will only slow down the miner.

If two threads are using the same GPU device the start time of each hash round is optimized based on the average time needed to calculate a bunch of hashes. This way to optimize the hash rate was first introduced by @SChernykh. This implementation based on the implementation in xmrig but differen in the details. - introduce a new config option `interleave` - implement thread interleaving

In the cuda backend for monero we start always twice as much threads as needed. Those threads are than removed after the AES matrix is copied to the shared memory. Never the less it is the result of an copy past bug. - start correct number of threads for `monero`

Allow to ship the miner with multiple cuda backends those depends on different driver versions. This will allow to support Turing/Volta and old Fermi GPU within one release. - add support to search for the first working CUDA backend - add some more messages to support better debugging (if a user has some issues)

If `comp_mode` is false the results on a windows platform will be invalid. The reason for that is that `ulong4` is in windows 16byte and in linux 32byte. thx @xmrig for finding and solving the issue fix #1873
