xmpp: make STARTTLS always required

TLS (or at the time, SSL) may have been an optional feature in the past,
but it's not anymore. These days it's far more likely that a server will
always want to require TLS in some form, so giving the user the ability
to turn it off just means we're giving users who won't understand the
consequences of their actions a knob to twiddle. In the very rare case
that a user actually *does* need STARTTLS to be an optional stream
feature, I don't think it's something we should support. For this rare
use case, they'll have to take the maintenance burden on themselves by
copy/pasting the StartTLS feature code and tweaking it for their needs.

Fixes #50

all: include close element in handler stream

Previously the close element was not included in the limited XML stream
passed to handlers. This made it possible to enter an infinite loop or
deadlock when trying to use the DecodeElement method of xml.Decoder's.
A regression test has also been added to make sure that we can't read
beyond the end of the element (which was previously the case but there
was no test for this, which was dangerous) and to make sure that the new
behavior (with the end element) is enforced.

all: move stanza wrapping to methods

Previously to wrap a payload in a stanza you would use the functions
WrapIQ, WrapMessage, and WrapPresence. Each of these took their
respective stanza types and a payload.
These have been moved to Wrap methods on the various stanza types that
take a payload to make them easier to use in handlers where you already
have the stanza.
The down side is that these methods now exist on types that embed a
stanza, which may be confusing since the payload will be ignored and
only the stanza will be used.

xmpp: only error on flush to closed stream

I'm not entirely sure if this behavior is correct, but it "feels right"
and it lets us pass the decoder (with its existing state) directly to
the features (so that trying to wrap it with xml.NewDecoder in parse
will return the original decoder). We should probably just change the
API to accept one to prevent anything else from being passed and
breaking the state on parse.
all: new session XML read/write API
