c10690aea2 TODO: add item to TODO list
We currently do a little too much work when we push the first buffer around
resulting in excessive caps checking. We can probably make this a little less
expensive.

89c42f8506 stepping: do flushing steps correctly
Note in the docs that a flushing step in PLAYING brings the pipeline to the lost
state and skips the data before prerolling again.

Implement the flushing step correctly by invalidating the current step
operation, which would activate the new step operation.

4b986a4a94 Add message to request a state change
Add a GST_MESSAGE_REQUEST_STATE that can be posted by element when they would
like to have the application change the state of the pipeline. the primary use
case is to pause the pipeline when an audio mixer is mixing a higher priority
stream but it can also be used for other purposes.

Add some docs and a unit test.

Implement the REQUEST_STATE message in gst-launch.
