Each plugin must provide its own unique key. Otherwise we will only ever
see one single plugin.

Right now running on i.MX6 is often broken because the imx6 videonode plugin is
not picked up since only the egl one is seen by the system. With the fix both plugins
provide their own unique key so both become visible.

Additionally, introduce a QT_VIDEONODE environment variable. This is useful to specify
which plugin to use. This is necessary in case multiple custom videonode plugins support
the same formats.

Don't use relaxed load and stores, we need to be stricter to avoid
problems with high frequency re-fills of the buffer. If we don't enforce
ordering we might end-up spending more time trying to acquire an open
slot in the buffer. Updating processes bytes is also moved off the
"OpenSL" thread.

Added some comments for improved readability.

Checking the sender of the mediaSourceReady signal to prevent accessing
the incorrect source resolver.

When the source resolver has finished the asynchronous operation and
the source resolver gets recreated in the player at the same time in a
different thread the signal mediaSourceReady still gets emitted from the
old source resolver.

The player assumes that the signal was emitted from the current source
resolver and accesses the unresolved media source in the
handleMediaSourceReady slot.

We where very strict about tearing down the audio device. While this is
a good strategy to avoid unnecessary resource usage, it also causes
excessive re-allocations, e.g., when transiting from start to stop and
back again. This can increase latency, especially in case where a short
clip is re-played at a high frequency.
This change also decrease the chance of the player ending up in some
unknown state where it drops audio clips without any warning.
