Alexander Block cd9c6994c2 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
