Document a bug related to the QuickTime graph now that it's confirmed fixed.

The issue was fixed in 37e3dec49a6baf9d984e335ab8785e22eaf227e5.

MediaInfo: Fix parsing from IAsyncReader.

 - Ensure we don't try to read unavailable data.
 - Correctly handle seek requests.
 - Don't stop the analysis too early.
MediaInfo: Don't use fastest parsing option.

Fastest parsing tends to miss some info that seems important to our users so use normal parsing speed instead.

Fixes #4730.
MediaInfo: Fix analysis of raw HEVC streams.

This patch has been upstreamed to MediaInfo as revision 6474 so there is no need to worry about it next time MediaInfo is updated.

Fixes #4891.

refclock.cpp: Avoid a possible (but very unlikely) integer overflow.

Fixes CID 966081.

Video renderers setting changes

- Mark VMR-7 (renderless) as unavailable on 64-bit build. (required libs
  are unavailable)
- Change default renderer on XP to VMR-7 (renderless). It will fallback
  to system default one (VMR-7 windowed) if it fails. This change will provide subtitle
  support with default settings.
- If EVR is unavailable on Vista+ select VMR-9 (renderless) instead of
  system default one. Again it will fallback when needed, and in fact it
  should never fail.
- Move madVR higher on the list.
Fix typo introduced in 8ae02c6203ea3296406b88910bfdefbf80a8614e.
Add temporary flag to allow EC_VIDEO_SIZE_CHANGED event to stabilize
