Make the emulation stop asynchronous to prevent deadlocks.

This may expose bugs which relied on the Main Thread to be suspended in the stopping state.
Frame: OnClose now handles asynchronous behaviour of DoStop().
Core: Return CORE_STOPPING even if hardware is already uninitialized.
FrameTools: Update GUI and disable Play button when in stopping state.
Check whether the core is running instead of checking if it is unitialized.

This properly handles the stopping state and more accurately represents the intended check.
Movie: Do not attempt to record input when the emulation has not started yet.

Fixes a null pointer exception when the user starts the recording during a state transition.

AVIDump: fix FFV1 encoding

ffmpeg 2.0 changed requirements for the FFV1 encoder and made them more strict,
requiring more fields of the input frame to be initialized. Explicitly setting
pixfmt, width and height solve the EINVAL issues with FFV1 encoding.

Original fix from http://ffmpeg.org/pipermail/libav-user/2013-October/005759.html
