61ea84093b Don't shutdown completely after handling SyntaxError.
The ``shutdown = True`` line was preventing the stream from reconnecting
after handling the error.

952260b423 Add ssl_cert event (direct).
The payload is a dictionary of parsed cert data, as provided by
Python's getpeercert() socket method. It unfortunately does not
provide much detail beyond basic info.

3ab7c8bcc3 Make socket_error run as a direct event to ensure that it is handled.
Socket errors that occur before stream processing begins could not be
handled as the event loop would not be running yet.

1e01903072 Revert "Remove stream feature handlers on session_start."
This reverts commit 4274f49ada.

The SASL mech was choking on this, so let's send it back for some
more refining.

4274f49ada Remove stream feature handlers on session_start.
Based on profiling, using around 35 stream handlers quarters the number
of basic message stanzas that can be processed in a second, in
comparison to only using the bare minimum of four handlers.

To help, we can drop handlers for stream features once the session
has started. So that we can re-enable these handlers when a stream
must restart, the 'stream_start' event has been added which fires
whenever a stream header is received.

The 'stream_start' event is a more generic replacement for the
existing start_stream_handler() method.

f6e30edbc4 Log received data AFTER filtering.
This allows applications to filter out sensitive information, such
as passwords, so that it won't appear in the logs.

It does mean that the debug logs will not show the actual received
data, and there will be no indication of tampering, unless the
filter author explicitly logs and notes that a change was made.

eff3330e75 Add support for incoming/outgoing filters.
A filter accepts and returns a stanza, but potentially modified.

To prevent sending/receiving a stanza, a filter may return None.

Incoming:
    self.add_filter('in', in_filter)

Outgoing:
    self.add_filter('out', out_filter)

Filters are applied in the order thay are added. However, you may
add an order parameter, which is the place in the list to insert the
filter:

    self.add_filter('in', in_filter, order=0)

efe1b9f5a9 Allow sending stanzas on session_end.
May set self.disconnect_wait=True so that all disconnect
calls wait for the send queue to empty, unless explicitly
overridden with wait=False.

The session_end now fires before closing the socket so
that final stanzas may be sent, such as unavailable presences
for components.

862a2a1440 Ensure that reconnection happens properly after connection loss.
Calling reconnect() simultaneously from multiple threads (like when

reconnect() calls.

deb52ad350 This change stops sleekxmpp from spending huge amounts of time unnecessarily computing logging data that may never be used. This is a HUGE performance improvement; in some of my test runs, unnecessary string creation was accounting for > 60% of all CPU time.
Note that using % in a string will _always_ perform the sting substitutions, because the strings are constructed before the function is called. So log.debug('%s' % expensiveoperation()) will take about the same CPU time whether or not the logging level is DEBUG or INFO. if you use , no substitutions are performed unless the string is actually logged

b8efcc7cf0 Don't just call self.disconnect in self.reconnect.

2a2ac73845 So using sys.excepthook to catch errors only works once.
The error bubbles through the event processing loop, breaking it and
hanging the application.

Instead, there is now a .exception(e) method on XMLStream which may
be overridden or reassigned that will receive all unhandled exceptions
(read: not XMPPError) from event and stream handlers.

d8d9e8df16 Fix stanza clobbering when replying to errors.
If a stanza handler raised an exception, the exception was processed

it is the copy that processes the exception using the original content.

973890e2c9 Added try/except for setting signal handlers.
Setting signal handlers from inside a thread is not supported in Python,

to detect SIGHUP or SIGTERM events. Those must be caught and managed by
the main program.

9c08e56ed0 SSL and signal fixes.
Made setting the SIG* handlers conditional on if the signal defined for

tends to require ssl.PROTOCOL_SSLv23.
