Fix panic when connection is reset immediately after establishing.

Added support for SASL PLAIN, from "Ildar Hizbulin" <hizel@vyborg.ru>.

Merge.

Added a license (and my email address).

Forgot to change the type of RosterItem.Jid to JID.

Changed the type of structure fields which hold JIDs from string to JID.

Added a JID.Bare() function, to product the bare JID as defined in the RFC.

Changed the JID type to be an alias of string, rather than a struct. This allows it to be used as a key in a map, among other benefits.

Updated to-do list.

Merge.

Allow the client to specify a host and port to connect to, rather than using SRV records.

Doc cleanup.

Removed a completed to-do item.

Removed uses of Generic from the Stanza types.

Doc fix.

Trying to be smarter about closing channels: Ask the application not to close the Send channel, but let us do that from Close() instead.

Make an attempt to only close the send channel if it's still open.

Don't call Close() twice.

Expose the Status.Fatal function.

Moved some code around.

gofmt

Changed order of operations in setError() so that the underlying error is reported.

Removed the weirdo logging facility. There's now a Debug variable which can be set which replaces the former debug log. NewClient() will return an error if something goes wrong setting up the connection.

Added a Close() function and fixed a couple of shutdown bugs.

gofmt

to-do update.

Listen for XMPP connection status changes, and print them out.

Renamed Extension.StanzaHandlers to StanzaTypes, and updated the doc comment.

Don't keep the password around after we've used it.

To-do list updates.

gofmt

Updated to-do list.

Simplified the API: There's only one constructor, and it does everything necessary to initiate the stream. StartSession() and Roster.Update() have both been eliminated.

Updated to-do list.

gofmt

Code reorder and doc cleanup.

Removed an unused parameter.

Made layers 1 and 3 more modular, shrinking the surface area of the coupling between them.

Function renames and improved doc.

Changed the inputControl channel to send a custom type.

gofmt

Renamed HandleStanza to SetCallback.

Split stream.go into layer1, layer2, layer3, and sasl.

Removed copyright statements.

Doc update.

Don't close the wrong end of a channel. But if we get an error, we can close the underlying socket.

Initial roster contents look like a result iq.

Doc update.

Start reading from the recv channel earlier.

Simplified and debugged the filter logic.

Fixed another logic error, caused by a shadowed variable name.

Fixed some logic errors and initialized some things that needed to be initialized.

Removed some unused code.

Fixed reversed-logic error in checking for duplicate stanza extension types.

Address a bug that can happen if no SRV records can be found.

Pass the TLS config as a parameter to the Client constructor. Updated the example program.
