bas-vk b59c8399fb internal/ethapi: add personal_sign and fix eth_sign to hash message (#2940)
This commit includes several API changes:

- The behavior of eth_sign is changed. It now accepts an arbitrary
  message, prepends the well-known string

        \x19Ethereum Signed Message:\n<length of message>

  hashes the result using keccak256 and calculates the signature of
  the hash. This breaks backwards compatability!
  
- personal_sign(hash, address [, password]) is added. It has the same
  semantics as eth_sign but also accepts a password. The private key
  used to sign the hash is temporarily unlocked in the scope of the
  request.
  
- personal_recover(message, signature) is added and returns the
  address for the account that created a signature.

Felix Lange 85e6c40c00 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.

Felix Lange 83877a0f9d tests: remove eth, node, accounts dependencies

Ricardo Catalinas Jiménez c20d6e5e4e crypto/sha3: Export Keccak-256 hash function
This hash function is slightly different from the standarized NIST SHA-3
as both of them use different domain separation bits.

Felix Lange 1b29aed128 crypto/secp256k1: verify recovery ID before calling libsecp256k1
The C library treats the recovery ID as trusted input and crashes
the process for invalid values, so it needs to be verified before
calling into C. This will inhibit the crash in #1983.

Also remove VerifySignature because we don't use it.
