Since the coinbase maturity is now allowed to be defined per chain and
the old blockchain.CoinbaseMaturity constant has been removed, this
updates the code accordingly.
Also, update glide.lock to use the required version of btcd.
This changes the wallet.Open function signature to remove the database
namespace parameters. This is done so that the wallet package itself
is responsible for the location and opening of these namespaces from
the database, rather than requiring the caller to open these ahead of
time.
A new wallet.Create function has also been added. This function
initializes a new wallet in an empty database, using the same
namespaces as wallet.Open will eventually use. This relieves the
caller from needing to manage wallet database namespaces explicitly.
Fixes#397.
Rather than the main package being responsible for opening the address
and transaction managers, the namespaces of these components are
passed as parameters to the wallet.Open function.
Additionally, the address manager Options struct has been split into
two: ScryptOptions which holds the scrypt parameters needed during
passphrase key derivation, and OpenCallbacks which is only passed to
the Open function to allow the caller to provide additional details
during upgrades.
These changes are being done in preparation for a notification server
in the wallet package, with callbacks passed to the Open and Create
functions in waddrmgr and wtxmgr. Before this could happen, the
wallet package had to be responsible for actually opening the managers
from their namespaces.
This contains the APIs to create and retrieve Voting Pools and Series (with
public/private keys) from a walletdb namespace, plus the generation of deposit
addresses (using m-of-n multi-sig P2SH scripts according to the series
configuration).
