e4c0fc81dd Return non-nil RPC results for 0 length slices.
If a JSON array result was successfully calculated, but the
slice/array is empty, the result must be marshaled as '[]' rather than
the JSON null value.  To do this in go, the RPC handlers should never
return nil slices for non-error returns, but return a non-nil slice
header with 0 length.

For example, an empty listtransactions result should be returned as
[]btcjson.ListTransactionsResult{}, rather than nil.

d863c75be7 Fix and simplify RPC server error handling.
This change rewrites much of the error handling for the RPC server
components to match a more idiomatic Go error handling style as well as
fix several issues regarding error equality checks.

0cba485793 Handle unopenable transaction stores.
If the transaction store cannot be opened and read (i.e. the version
is too old to be deserialized), the wallet is marked unsynced and
rewritten, and a new empty transaction store is written over the
previous.

6597d789b7 Avoid slice out-of-bounds indexing panic.
The gettransaction handler was attempting to lookup the "sent-to"
address of an outgoing transaction from the transaction store (as a
wallet credit).  This is the incorrect address when sending to an
address controlled by another wallet, and panics when there are no
credits (for example, sending to another wallet without any change
address).  Instead, use the first non-change output address is used as
the address of the "send" result.

This fixes the panic reported when debugging issue .

While here, fix the category strings used for wallet credits to
support immature and generate (the categories for coinbase outputs).

368204a58a Fix rescans across wallet process restarts.
This change immediately writes a new empty transaction store out to
disk if the old one could not be read.  Since old transaction store
versions are not read in at start, and were previously not written out
until new transaction history was received, it was possible that a
full rescan started and finished without ever marking a synced tx
history for the next wallet start.

2c3845bbbd Prevent full handshake rescans on btcd reconnect.
If a rescan fails (for example, due to a disconnected btcd) in the
btcd handshake, the last block height from a rescanprogress
notification should be used for the next rescan job on next wallet
connect.  Previously, this rescan would always start at the earliest
block height for any wallet address if the transaction store could not
be read at wallet startup.  This change unsets the boolean flag which
would cause a full rescan at next connect when a rescan progress
notification is received and a partial sync height is written.

Instead, follow the pattern laid out by mainnet, testnet3, and regtest

242cb22719 Check every error.
This change is the result of using the errcheck tool
(https://github.com/kisielk/errcheck) to find all unchecked errors,
both unassigned and those assigned to the blank identifier.

Every returned error is now handled in some manner.  These include:

  - Logging errors that would otherwise be missed
  - Returning errors to the caller for further processing
  - Checking error values to determine what to do next
  - Panicking for truely exceptional "impossible" errors

On the subject of panics, they are a sharp tool and should be used
sparingly.  That being said, I have added them to check errors that
were previously explicitly ignored, because they were expected to
always return without failure.  This could be due to fake error paths
(i.e. writing to a bytes.Buffer panics for OOM and should never return
an error) or previous logic asserts that an error case is impossible.
Rather than leaving these unhandled and letting code fail later,
either with incorrect results or a nil pointer dereference, it now
produces a stack trace at the error emit site, which I find far more
useful when debugging.

While here, a bunch of dead code was removed, including code to move
pre-0.1.1 uxto and transaction history account files to the new
directory (as they would be unreadable anyways) and a big chunk of
commented out rpcclient code.

c3224f4fbc Begin update to use btcnet.Params.
This is an intial pass at converting the btcwallet and deps codebases
to pass a network by their parameters, rather than by a magic number
to identify the network.  The parameters in params.go have been
updated to embed a *btcnet.Params, and all previous uses of cfg.Net()
have been replaced with activeNet.{Params,Net} (where activeNet is
the global var for the active network).

Although dependancy packages have not yet been updated from using
btcwire.BitcoinNet to btcnet.Params, the parameters are now accessible
at all callsites, and individual packages can be updated to use btcnet
without requiring updates in each external btc* package at once.

While here, the exported API for btcwallet internal library packages
(txstore and wallet) have been updated to pass full network parameters
rather than the btcwire definition of a network.

the btcd user and password settings are shared with the client auth
settings.

2f0a9b1435 Simplify a switch statement in OutputAmount.
Instead of using 3 fallthroughs with obscure cases, use a single
switch statement with just a one case.  This switch is only evaluated
if a previous if statement body is entered.  Functionally no
different, but imo this much easier to read, and removes two uses of !
to negate bools.

e39fa32487 Fix listtransactions category for coinbase outputs.
The category for a received coinbase output should be "generate" for a
mature coinbase (one that has reached btcchain.CoinbaseMaturity
confirmations), or "immature" if the required number of confirmations
has not been reached yet.  New Confirmed and Confirmations methods
have been added to the transaction store's TxRecord type to check if
the required number of confirmations have been met for coinbase
outputs.

While here, update the main package to use the new TxRecord methods,
rather than duplicating the confirmation checking code in two places.

17ebf9461f Rename connect option to rpcconnect.
The connect option is already used by btcd to force a connection to
other full node peers.  Wallet does not talk directly with these
peers, so the connect option is being renamed to something unique for
an RPC client connection.
