Remove the addresses field from TransactionDetails.Output. It is
assumed that the caller is able to deserialize the transaction and
encode the output scripts to addresses, so this is unnecessary server
overhead and conflicts with the current API philosophy of not
duplicating data already included in another field.
Since there is no additional data included for outputs not controlled
by the wallet, remove the `mine` specifier from the Output message and
replace it with an output index. Only include messages for controlled
outputs, rather than creating messages for both controlled and
uncontrolled outputs. Rename the repeated field from `outputs` to
`credits` to be consistent with the `debits` field.
Bump major API version as this is a breaking change.
Closes#408.
This updates both btcsuite and external dependencies to their latest
versions. In particular, gRPC was updated to version 1.0.3 and bolt
to 1.3.0.
The walletrpc package needed to be regenerated for the gRPC update.
While here, update the Travis-CI script so this can be tested there.

StartBtcdRpc becomes StartConsensusRpc.
This is useful for forks such as decred or if someone were to write
another compatible server.
Bump up the api version as this is a change.
This is a rather monolithic commit that moves the old RPC server to
its own package (rpc/legacyrpc), introduces a new RPC server using
gRPC (rpc/rpcserver), and provides the ability to defer wallet loading
until request at a later time by an RPC (--noinitialload).
The legacy RPC server remains the default for now while the new gRPC
server is not enabled by default. Enabling the new server requires
setting a listen address (--experimenalrpclisten). This experimental
flag is used to effectively feature gate the server until it is ready
to use as a default. Both RPC servers can be run at the same time,
but require binding to different listen addresses.
In theory, with the legacy RPC server now living in its own package it
should become much easier to unit test the handlers. This will be
useful for any future changes to the package, as compatibility with
Core's wallet is still desired.
Type safety has also been improved in the legacy RPC server. Multiple
handler types are now used for methods that do and do not require the
RPC client as a dependency. This can statically help prevent nil
pointer dereferences, and was very useful for catching bugs during
refactoring.
To synchronize the wallet loading process between the main package
(the default) and through the gRPC WalletLoader service (with the
--noinitialload option), as well as increasing the loose coupling of
packages, a new wallet.Loader type has been added. All creating and
loading of existing wallets is done through a single Loader instance,
and callbacks can be attached to the instance to run after the wallet
has been opened. This is how the legacy RPC server is associated with
a loaded wallet, even after the wallet is loaded by a gRPC method in a
completely unrelated package.
Documentation for the new RPC server has been added to the
rpc/documentation directory. The documentation includes a
specification for the new RPC API, addresses how to make changes to
the server implementation, and provides short example clients in
several different languages.
Some of the new RPC methods are not implementated exactly as described
by the specification. These are considered bugs with the
implementation, not the spec. Known bugs are commented as such.
