This updates all code to make use of the new chainhash package since the
old wire.ShaHash type and related functions have been removed in favor
of the abstracted package.
Also, while here, rename all variables that included sha in their name
to include hash instead.
- Create FutureGenerateResult type with Receive() method
- Create GenerateAsync method for Client which returns a
FutureGenerateResult
- Create Generate method for Client which calls GenerateAsync
and then calls Receive() on the returned FutureGenerateResult
This commit contains several changes needed to update the client to use
the latest version of btcjson. In addition, it contains a couple of other
minor changes along the way.
While the underlying changes are quite large, the public API of this
package is still the same, so caller should generally not have to update
their code due to that. However, the underlying btcjson package API has
changed significantly. Since this package hides the vast majority of that
from callers, it should not afffect them very much. However, one area in
particular to watch out for is that the old btcjson.Error is now
btcjson.RPCError, so any callers doing any type assertions there will need
to update.
The following is a summary of the changes:
- The underlying btcjson significantly changed how commands work, so the
internals of this package have been reworked to be based off of requests
instead of the now non-existant btcjson.Cmd interface
- Update all call sites of btcjson.New<Foo>Cmd since they can no longer
error or take varargs
- The ids for each request are part of the request now instead of the
command to match the new btcjson model and are strict uint64s so type
assertions are no longer needed (slightly improved efficiency)
- Remove the old temporary workaround for the getbalance command with an
account of "*" since btcwallet has since been fixed
- Change all instances of JSONToAmount to btcutil.NewAmount since that
function was removed in favor of btcutil.Amount
- Change all btcws invocations to btcjson since they have been combined
The string needs to be unmarshaled rather than returned directly otherwise
it will have an extra set of quotes plus it's safter to properly unmarshal
it.

The submitblock RPC returns a string containing an error if it failed for
any reason. This comment detects a non-null return from submitblock and
converts that string to an error which is returned.
There are several RPCs which accept a pointer to a hash, transaction,
block, etc. Previously not all RPCs handled being passed a nil pointer
consistently.
Closes#4.
