Team Red Miner v0.8.0

Biggest release in a long while with rewritten ethash kernels and new mining modes for all gpu types!

Users are highly(!) recommended to take a few minutes to read the 0.7-to-0.8 migration guide and the new ethash tuning guide.

Key highlights:

• Polaris: Efficiency and slight hashrate increase. B-mode reintroduced for added hash. B-mode must be enabled with --eth_aggr_mode or --eth_config=Bxxx.

• Vega 56/64: greatly improved base kernel for efficiency. New B-mode that can shave off additional 1-2W on top of the A-mode kernel. B-mode must be enabled manually with --eth_config (--eth_aggr_mode does not apply). Tuning numbers have changed - do NOT keep your old static --eth_config values.

• Radeon VII: huge boost with its new C-mode but requires a special Linux setup. Can now do 100 MH/s on most air cooled VIIs. See tuning guide.

• 5700/5700XT: can shave off as much as 8-9W(!) of power using the new B-mode and dropping core clk+voltage. B-mode now the default mining mode. Unless you retune your core clk+voltage you will see a tiny power draw increase instead and not benefit from the upgrade, so read the migration guide.

• 5600XT: new B-mode has a much smaller effect. A-mode remains the default mining mode. See new tuning guide for more details.

• The dag cache is NOT compatible with the new B/C-modes. ETH+ZIL switchers have to choose between caching the epoch 0 dag and using the new mining modes.

• Ethash 4GB kernels NOT rewritten in this release, performance remains the same as in 0.7.x.
