  1. sysbus: Drop sysbus_from_qdev() cast macro 

    Replace by SYS_BUS_DEVICE() QOM cast macro using a scripted conversion.
Avoids the old macro creeping into new code.

Resolve a Coding Style warning in openpic code.

  2. vnc: fix possible uninitialized removals 

    Some VncState values are not initialized before the Websocket handshake.
If it fails QEMU segfaults during the cleanup. To prevent this behavior
intialization checks are added.

  3. vnc: added initial websocket protocol support 

    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.

  4. vnc: added buffer_advance function 

    Following Anthony Liguori's Websocket implementation I have added the
buffer_advance function to VNC and replaced all related buffer memmove
operations with it.

  5. tcg/target-arm: Add missing parens to assertions

comparison in operand of ‘&’ [-Werror=parentheses]

tcg/arm/tcg-target.c:1357:5: error: suggest parentheses around
comparison in operand of ‘&’ [-Werror=parentheses]

which meant that we would mistakenly always assert if running
a QEMU built with debug enabled on ARM.
