Roman Khimov	23464401bc	core/state: merge spent and unspent coins state, use it to store more things ... This change reduces pressure on DB by doing the following things: * not storing additional KV pair for SpentCoin * storing Output right in the UnspentCoin, thus eliminating the need to get a full transaction from DB At the same time it makes UnspentCoin more fat and hot, but it should probably worth it. Also drop `GetUnspentCoinStateOrNew` as it shouldn't ever existed, UTXOs can't come out of nowhere. 1.5M block import time (VerifyBlocks disabled) on AMD Ryzen 5 1600/16GB/HDD, before: real 302m9.895s user 96m17.200s sys 13m37.084s after: real 159m16.551s user 69m58.279s sys 7m34.334s So it's almost two-fold which is a great improvement.	2020-03-11 12:40:02 +03:00
