Pull in version 376872d99.

Several changes including:
- binary/typed array support in websock.js
- unix socket support
- multiple target support via config file(s)
- prefer IPv6 option

With tight we can't ever use FBU.rects being 0 as an indication of
a full frame having been drawn.

Fixes nova rpc package.

Fix nova flag API change

Remove old flagfile support

default_flagfile has been removed from the nova trunk in favour of .ini files (https://github.com/openstack/nova/commit/7e3e9b8e9cea4f1bf78d127ffb915b79c854fdbe)

This will keep copyrect rendering actions in order with tight and tightPNG
rendering actions (otherwise you can get visual image corruption when
they are mixed together).

Warning:

RAW, RRE and HEXTILE still use immediate render commands so there is
still the risk of out-of-order rendering if RAW, RRE, and HEXTILE are
mixed with tight and tightPNG. Copyrect will work with either because
the renderQ_push function will render copyrects immediately if they
are the only thing being pushed on the queue.

The imgQ code in RFB should be a generic rendering queue system in
Display.

The reason for the render queue in the first place is that images
loaded from raw data URI strings aren't immediately ready to display
so we have to wait for them to complete 'loading'. However, when data
URI images are mixed with other types of rendering actions then things
can get out of order. This is the reason for the rendering queue.

Currently this only keeps display actions for tight and tightPNG
related actions in order (because they use a mix of fills, raw pixel
data and data URI images).

This related to https://github.com/kanaka/noVNC/issues/145

The real fix is to QEMU so that this doesn't happen which was
submitted as a patch to the mailinglist right before this.

- Also add docs/release.txt instruction file.

Fixes https://github.com/kanaka/noVNC/issues/163

When using an encoding with raw images (tight, tightPNG) we need to
draw those image relative to the viewport so that clipping works when
the viewport isn't at 0, 0.

RealVNC 4.6 Mac Support.

Fix python 2.4 CClose exception handling.

Fix rpc initialization issue

 * rpc flags now must be manually initialized.

Unfortunately the values for those duplicate keys are not the same and
I'm not sure which ones are more correct. However, for now, I've
commented out the second occurrence.

This data is generated from /usr/include/X11/keysymdef.h using the
utils/u2x11 script.

The close event will also fire so trying to fail the connection twice
is unhelpful and hiding status information.
