Detect SSE2 support

Compilation on an older 32-bit Athlon XP chip fails with the error
"./Utils/AEUtil.h:50:12: error: '__m128i' does not name a type"
This is because the __m128i type is only available on SSE2 platforms.
Modify the preprocessor logic to detect SSE and SSE2 support separately.

The "emmintrin.h" header should only be included on SSE2 platforms as
well.
interfaces: add ILanguageInvoker and ScriptInvocationManager
python: implement CPythonInvoker (replacing XBPyThread)
XBPython: cosmetics
python: let XBPython implement ILanguageInvocationHandler
cosmetics: remove trailing spaces from XBPython.h/cpp
python: register XBPython for .py files
use CScriptInvocationManager instead of XBPython

CdripEncoderFFmpeg: Remove vorbis special casing.

Since we have a libvorbis encoder, we should probably not try to encode vorbis with ffmpeg: http://xiphmont.livejournal.com/51160.html
DllAvFormat: Map avformat_alloc_output_context2.
[pvr] fix: CAddonCallbacksAddon::GetAddonSetting doesn't returns slider setting value.
CDRip EncoderFFmpeg: Modernize.

Convert to use avformat_alloc_output_context2 and avcodec_encode_audio2.
Convert input audio to the format requested by the encoder if needed.
CDRip FFmpeg: Reduce a bit the avio buffer size as suggsted by libavformat documentation.
