accounts/abi/bind/backends: remove nil and remote backends The remote backend is superseded by ethclient. The nil backend's stated purpose was to enable testing of accounts/abi/bind. None of its methods actually worked. A much simpler way to get a crashing backend is to simply pass nil as the backend. With a one-line change to the generator (removing two explicit interface assertions), passing nil actually works. Removing these backends means that less changes are required later.

`
accounts/abi/bind/backends: remove nil and remote backends The remote backend is superseded by ethclient. The nil backend's stated purpose was to enable testing of accounts/abi/bind. None of its methods actually worked. A much simpler way to get a crashing backend is to simply pass nil as the backend. With a one-line change to the generator (removing two explicit interface assertions), passing nil actually works. Removing these backends means that less changes are required later.

// Generate a new random account and a funded simulator
accounts, crypto: move keystore to package accounts The account management API was originally implemented as a thin layer around crypto.KeyStore, on the grounds that several kinds of key stores would be implemented later on. It turns out that this won't happen so KeyStore is a superflous abstraction. In this commit crypto.KeyStore and everything related to it moves to package accounts and is unexported.

core: refactor genesis handling This commit solves several issues concerning the genesis block: * Genesis/ChainConfig loading was handled by cmd/geth code. This left library users in the cold. They could specify a JSON-encoded string and overwrite the config, but didn't get any of the additional checks performed by geth. * Decoding and writing of genesis JSON was conflated in WriteGenesisBlock. This made it a lot harder to embed the genesis block into the forthcoming config file loader. This commit changes things so there is a single Genesis type that represents genesis blocks. All uses of Write*Genesis* are changed to use the new type instead. * If the chain config supplied by the user was incompatible with the current chain (i.e. the chain had already advanced beyond a scheduled fork), it got overwritten. This is not an issue in practice because previous forks have always had the highest total difficulty. It might matter in the future though. The new code reverts the local chain to the point of the fork when upgrading configuration. The change to genesis block data removes compression library dependencies from package core.

core: refactor genesis handling This commit solves several issues concerning the genesis block: * Genesis/ChainConfig loading was handled by cmd/geth code. This left library users in the cold. They could specify a JSON-encoded string and overwrite the config, but didn't get any of the additional checks performed by geth. * Decoding and writing of genesis JSON was conflated in WriteGenesisBlock. This made it a lot harder to embed the genesis block into the forthcoming config file loader. This commit changes things so there is a single Genesis type that represents genesis blocks. All uses of Write*Genesis* are changed to use the new type instead. * If the chain config supplied by the user was incompatible with the current chain (i.e. the chain had already advanced beyond a scheduled fork), it got overwritten. This is not an issue in practice because previous forks have always had the highest total difficulty. It might matter in the future though. The new code reverts the local chain to the point of the fork when upgrading configuration. The change to genesis block data removes compression library dependencies from package core.

accounts, crypto: move keystore to package accounts The account management API was originally implemented as a thin layer around crypto.KeyStore, on the grounds that several kinds of key stores would be implemented later on. It turns out that this won't happen so KeyStore is a superflous abstraction. In this commit crypto.KeyStore and everything related to it moves to package accounts and is unexported.

accounts/abi/bind, internal/ethapi: binary search gas estimation (#3587) Gas estimation currently mostly works, but can underestimate for more funky refunds. This is because various ops (e.g. CALL) need more gas to run than they actually consume (e.g. 2300 stipend that is refunded if not used). With more intricate contract interplays, it becomes almost impossible to return a proper value to the user. This commit swaps out the simplistic gas estimation to a binary search approach, honing in on the correct gas use. This does mean that gas estimation needs to rerun the transaction log(max-price) times to measure whether it fails or not, but it's a price paid by the transaction issuer, and it should be worth it to support proper estimates.
