Add libjingle version 0.4.0, plus some patches

that are described in README.chromium and
a .diff file, under review separately.

I removed some of the weightier
autoconf/configure scripts.  This brought the
size of the library from 3.8MB to about 2.3MB.

BUG=none
TEST=none

+//! The XMPP connection engine.
+//! This engine implements the client side of the 'core' XMPP protocol.
+//! To use it, register an XmppOutputHandler to handle socket output
+//! and pass socket input to HandleInput.  Then application code can
+//! set up the connection with a user, password, and other settings,
+//! and then call Connect() to initiate the connection.
+//! An application can listen for events and receive stanzas by
+//! registering an XmppStanzaHandler via AddStanzaHandler().
