Implement named devnets (#1791) * Initial devnet * Move genesis block adding into its own method * Introduce -allowprivatenet to lift limitation on RFC1918 addresses Normally, RFC1918 (192.168.x.x/10.x.x.x/...) addresses are not allowed to be relayed. Also, masternodes won't start when the address is considered invalid. This is needed to test local devnet or regtest based networks. * Lift the requirement of minimum MN age for regtest/devnet * Implement named devnets This allows the creation of multiple independent devnets. Each one is identified by a name which is hardened into a "devnet genesis" block, which is automatically positioned at height 1. Validation rules will ensure that a node from devnet=test1 never be able to accept blocks from devnet=test2. This is done by checking the expected devnet genesis block. The genesis block of the devnet is the same as the one from regtest. This starts the devnet with a very low difficulty, allowing us to fill up needed balances for masternodes very fast. Also, the devnet name is put into the sub-version of the VERSION message. If a node connects to the wrong network, it will immediately be disconnected. * Allow to select multiple addresses from the same group in devnet/regtest The selection code normally only allows to select addresses from the same group (e.g. 192.168.x.x) once. This results in connecting to only a single node in devnet/regtest. * Show the devnet name in the title bar and on the loading screen * Add AllowMultipleAddressesFromGroup to chainparams and use it in net.cpp * Remove unused/unneeded scripts from devnet geneses creation 1. OP_RETURN not needed in input script of devnet genesis 2. genesisOutputScript was unused * Fix copy/paste error in -allowprivatenet description * Improve -devnet parameter error handling - Only allow one of -devnet, -regtest or -testnet - Only allow -devnet=name to be specified once * Use different datadir for each devnet * Fix `devnet-devnet` issue * Fix devnet splashscreen (should use testnet img) * Avoid passing devNetName around (most of the time) * Remove nMaxTipAge from CDevNetParams Not present anymore after rebase on develop
