0d40bf901d Implement alternative auth for websockets.
The previous websocket code required HTTP auth headers to be sent in order
to use the websocket.  While this makes sense for most applications, some
use cases such as javascript-based websockets from browsers do no have the
ability to send headers.

This commit modifies the authentication logic to allow an alternative
authentication mechanism when HTTP auth headers can't be sent.  In
particular, it introduces a new JSON-RPC command named authenticate which
accepts the username and passphrase for the RPC server.  The command is
only required if the connetion has not already been authenticated via HTTP
auth headers and it must be the first command to be received.  Sending any
other command will immediately disconnect the websocket.

ok from @owainga and @jrick.

This closes #77.

d3e4bcdcf5 Fix sendrawtransaction for websockets.
This fixes two issues: first, the sendrawtransaction handler had an
extra character in the key in the websocket handler map, preventing
the handler from never running.  Second, a nil pointer dereference was
removed from the handler.

This change fixes the minedtx notifications for btcwallet, since the
websocket-handler now runs instead of falling back to the legacy RPC
handler.

f12ca20372 Enable memdb support.
This commit adds the btcdb memdb backend as a supported database type.
Note that users will NOT want to run in this mode because, being memory
only, it obviously does not persist the database when shutdown.

It is being added for testing purposes to help prevent constant abuse to
developer's hard drive when churning the block database multiple times a
day.

f309e899f3 Make use of the new btcdb functions.
This commit switches the handleGetHeadersMsg function to make use of the
new FetchBlockHeightBySha and FetchBlockHeaderBySha functions in btcdb.

Also, while here, nuke the header copy which is no longer required due to
the recent btcwire changes.

7ad6e235ad Reduce the initial idle timeout to 30 seconds.
This commit reduces the initial idle timeout before version negotiation
has happened on a new peer to 30 seconds.  Previously it could take 5
minutes due to the general idle timeout.

8c7d44c8dc Add authentication deadline to RPC server cnxns.
Previously it was possible to open a connection to the RPC server, never
authenticate, and idle forever.

This is work toward #68.

0fbd962f8a Use our own websocket.Server instance.
The websocket.Server used the by websocket.Handler type automatically adds
a handshake function which prevents connections when the Origin header is
not set.  Not all clients send this information and we already require
authentication headers as the auth mechanism anyways.

9474ef29d7 Use strings in websocket send/receive.
The websocket package assumes binary blobs if []byte is used.  Since we're
using JSON-RPC for all the websocket communications, it should be text
based.

This commit changes the websocket Send/Receive and associated channels to
strings accordingly.

bd98836a2b Fix several bugs in the RPC server shutdown.
The RPC server was performing some of the shutdown logic in the wrong
order, that is, logging the the server has shut down, waiting for all
server goroutines to finish, and then closing a channel to notify
server goroutines to stop.  These three items have been reversed to
fix a hang where goroutines currently being waited on had not shut
down because they did not receive the notification.

While here, the server waitgroup was incremented for a goroutine that
was running without it, another select statement was added to stop a
duplicate close (which never occured last commit when I added the
select statements), and the "stopping rescan" logging was moved to
debug to make the ^C shutdown logging nicer.

477b733ed9 Make Go 1.2 requirement more noticeable.
It was pointed out in #76 that if you arrived to the Update section
of the README without seeing the Installation section, the requirement for
Go 1.2 is easy to miss.  This commit builds the requirement in the
Installation section and adds it to the Updating section as well to
hopefully make it more noticable.

6222b1d8cc Rework and Improve addblock utility.
The addblock utility was originally written as a quick debug tool during
initial development to populate blocks into the database.  However, now
that it has been designated as the standard way to import bootstrap.dat
(and indeed block data files in general), it was lacking a few features
such as properly checking against the chain rules and known good
checkpoints.

This commit reworks and improves the utility in several ways:

- Imported blocks are now checked against the chain rules including
  checkpoints to ensure they match the known good chain
- The utility now properly shuts down after processing all blocks
- Attempting to import orphan blocks (blocks which build off a block you
  don't yet have in the database) returns an error
- Blocks that are already known are now skipped instead of causing an
  error which means you can stop and restart the import mid-way through
  without issues or start it after you've already downloaded a
  portion of the chain
- The block height is no longer assumed to start at 0 which means input
  files that start later in the chain will work properly so long as you
  already have the chain at least up to the point of the block just before
  the first one in the input file
- Improved error handling and reporting
- How often the progress display is shown is now configurable
- Statistics about how many blocks were processed, imported, and already
  known are now displayed after the input file has been fully processed

This resolves comments made in #60.

JSON-RPC specifications sending notifications as requests with an
empty ID.

The notification request context handling has been greatly cleaned up
now that IDs no longer need to be saved when sending notifications.

3946d84887 Make use of the new size hint functions in btcwire.
This commit changes a couple of sections which deal with large lists of
inventory vectors to use the new size hint functions recently added to
btcwire.  This allows a bit more efficiency since the size of the list is
known up front and we can therefore avoid dynamically growing the backing
array several times.  This also helps avoid a Go bug that leaks memory on
appends and GC churn.

462bc5a031 Update for recent btcscript API changes.
This commit changes all code which deals with extracting addresses from
scripts to use the btcscript API ExtractPkScriptAddrs which in turn makes
use of the new btcutil.Address interface.

This provides much cleaner code for dealing with arbitrary script
destinations which is extensible without having to churn the APIs if new
destination types are added.

dd7c910e86 Enable use of a different proxy for .onion addresses.
This implements --onion (and --onionuser/--onionpass) that enable a
different proxy to be used to connect to .onion addresses. If no main
proxy is supplied then no proxy will be used for non-onion addresses.

Additionally we add --noonion that blocks connection attempts to .onion
addresses entirely (and avoids using tor for proxy dns lookups).

the --tor option has been supersceded and thus removed.

Closes #47
