This adds opengl rendering support to the gtk ui, using egl.
It's off by default for now, use 'qemu -display gtk,gl=on'
to play with this.

Note that gtk got native opengl support with release 3.16.
There most likely will be a separate implementation for 3.16+,
using the native gtk opengl support.  This patch covers older
versions (and for the time being 3.16 too, hopefully without
rendering quirks).

I've ported the SDL1.2 code over, and rewritten it to use the SDL2 interface.

The biggest changes were in the input handling, where SDL2 has done a major
overhaul, and I've had to include a generated translation file to get from
SDL2 codes back to qemu compatible ones. I'm still not sure how the keyboard
layout code works in qemu, so there may be further work if someone can point
me a test case that works with SDL1.2 and doesn't with SDL2.

Some SDL env vars we used to set are no longer used by SDL2,
Windows, OSX support is untested,

I don't think we can link to SDL1.2 and SDL2 at the same time, so I felt
using --with-sdlabi=2.0 to select the new code should be fine, like how
gtk does it.

v1.1: fix keys in text console
v1.2: fix shutdown, cleanups a bit of code, support ARGB cursor

v2.0: merge the SDL multihead patch into this, g_new the number of consoles
needed, wrap DCL inside per-console structure.

Delete an unnecessary dependency for cocoa.o; we already have
a general rule that tells Make that we can build a .o file
from a .m source using an ObjC compiler, so this specific
rule is unnecessary. Further, it is using the dubious construct
"$(SRC_PATH)/$(obj)" to get at the source directory, which will
break when $(obj) is redefined as part of the preparation for
per-object library support.

This is minimalistic and just contains the basic widget infrastructure.  The GUI
consists of a menu and a GtkNotebook.  To start with, the notebook has its tabs
hidden which provides a UI that looks very similar to SDL with the exception of
the menu bar.

The menu bar allows a user to toggle the visibility of the tabs.  Cairo is used
for rendering.

I used gtk-vnc as a reference.  gtk-vnc solves the same basic problems as QEMU
since it was originally written as a remote display for QEMU.  So for the most
part, the approach to rendering and keyboard handling should be pretty solid for
GTK.

This patch adds basic Websocket Protocol version 13 - RFC 6455 - support
to QEMU VNC. Binary encoding support on the client side is mandatory.

Because of the GnuTLS requirement the Websockets implementation is
optional (--enable-vnc-ws).

To activate Websocket support the VNC option "websocket"is used, for
example "-vnc :0,websocket".
The listen port for Websocket connections is (5700 + display) so if
QEMU VNC is started with :0 the Websocket port would be 5700.
As an alternative the Websocket port could be manually specified by
using ",websocket=<port>" instead.

Parts of the implementation base on Anthony Liguori's QEMU Websocket
patch from 2010 and on Joel Martin's LibVNC Websocket implementation.

vnc-tls.h is included by vnc.h, and it includes gnutls/gnutls.h.
Hence, GnuTLS header files are needed by all files that include
vnc.h, most notably qmp.c.  Move these flags to QEMU_CFLAGS for
simplicity.
