Fix RealText subtitle parsing.

The parser didn't work at all and could even crash in some cases.

It seems like nobody uses this format being that this issue exists from the very beginning and never was reported. However the fix was easy so it doesn't hurt to keep it...

Fixes #5067.
DX9AllocatorPresenter: Skip to failure when no D3D device was allocated.

Also make the Sync Renderer code consistent with that change.

Fixes #3991.
Video renderers: Ensure the device exists before allocating the surfaces.

Fixes #2626.
Internal LAV Video Decoder: Support Cinepack and QPEG in low-merit mode.

Those codecs are disabled by default by LAV Video Decoder but it should be safe enough to use them in low-merit mode.

Fixes #3647.
Sync Renderer: Add more error checking when adding the SyncClock filter.

MPC-HC could crash if something went wrong.

Fixes #3742.
Update AStyle to v2.05.

Workaround some regressions while at it...
(WIP/Broken) Disable the time tooltip shadow for incompatible video renderers.

Some video renderers cause the tooltip shadow to be replaced by an opaque black box.

Fixes #1415.
(WIP/Broken) Try to find out if VMR-7 uses overlays, without luck so far...
Don't force any background color for the Shockwave graph.

This commit fixes #1747.
