[DVDStreamInfo] Fix 'CDVDStreamInfo::operator=' should return 'CDVDStreamInfo &'.
Read CD audio USB drive bug fixed

libcdio seems to allow read no more than about 10 audio sectors at once when CD audio device is connected via USB.
This patch makes XBMC read small number of sectors if default one fails. It uses more CPU but allows to use USB CD devices.
Tested on GNU/Linux x86 and RPi. (On Rpi OMXPlayer does not play CD, but I can rip tracks).
use tinyxml's Attribute() instead of QueryBoolAttribute() to stay compatible with tinyxml 2.5.x
[win32][added] Hybrid shutdown on Windows 8

[AE] AERemap: Fix mixing front and rear channels in some 5.1 setups

Fix the case when the input announces BR and BL instead of SR and SL,
e.g. when the following channels are in:
input:  FL FR FC LFE SL SR
output: FL FR BL BR  FC LFE
This leads to wrong mix front and rear channels,
(e.g. when playing AC3 test files).
The commit is handling those cases.

Special thanks to @fritsch for helping to track the problem down
and initial test patches.
