* Add from to eth_transact / xeth.Transact and add static pass in lieu
of integrating with native Mist window for user passphrase entry
* Make eth_accounts return AccountManager.Accounts()
* Add a Generate Key menu item in Mist
* Add blocktest cmd and support for block tests files in
tests/BlockTests , the launched node does not connect to
network, resets state with a genesis block from the test file
and starts the RPC API
* Add block header gas limit validation in ValidateBlock function,
see eq 39 and 45 in yellow paper. Before it was calculated _for_
the block instead of validated.
* Use the block header gas limit when setting the gas pool instead
of calculating the value for the block.
* Change account signing API to two sign functions;
Sign without passphrase - works if account is unlocked
Sign with passphrase - always works and unlocks the account
* Account stays unlocked for X ms and is then automatically locked
* Ensure the ECIES shared key is padded with zero bytes if it's
smaller than the requested key length.
* Split the ECIES shared key error into two;
one for when the generated key is too big for the params
and one for when it's nil (point of infinity returned by the
curve scalar multiplication).
* Move random entropy functions to new package randentropy
* Add function to get n bytes entropy where up to first 32
bytes are mixed with OS entropy sources
* Use crypto.Sign instead of directly calling secp256k1 lib
* Rename UserAccount to Account and Addr to Address (for consistency)
* Change AccountManager.Sign to take ptr to Account instead of
address byte array
* Simplify copying of Accounts in Accounts()
* PubkeyToAddress and GetEntropyCSPRNG now exported
* Add initial UserAccount and AccountManager structs
* Add NewAccount, Sign and Accounts functions
* Refactor key stores to use key address as main identifier
while keeping the UUID.
* Use key address as file/dir names instead of UUID
* ImportPreSaleKey takes a KeyStore, a presale key JSON (e.g. file content)
and a password string. It stores the key in the given key store.
* Refactored common AES decryption and moved some functions to crypto.go
* Remove flags field from key struct
* Change JSON struct fields from string to []byte
* Change GenerateNewKey API to take io.Reader for random source
* Remove mixing entropy source function
* Use testing Fatal in tests
* Simplify scrypt constants with const block
* Add key store constructors and make their types private
* Simplify key store and file namings to be less Java Enterprise™
* Change test error logging to use t.Error(err)
* Reduce number of naked returns (just like my ex-gf)
* Simplify file reading path code
* Add new generic key_store interface
* Add new plaintext key store storing unprotected keys on disk
* Add new encrypted key store storing encrypted keys on disk
* Add new entropy mixing function using OS and go runtime sources
