... to avoid accepting unhandled duration query result.

... rather than carrying on with NULL buffer.

State change to PAUSED can be done async, so if this happens, we need
to wait for the change to be done (or failed).

If the interlaced flag is not present in the caps, we assume the
data is not interlaced, instead of leaving the boolean uninitialized.

pa_stream_* functions return negative on error, despite the defines
for error codes being positive.

I only got to repro the error twice, so I'm not sure 100% sure this
fixes the issue (the negative var being uninitialized after returning
from pa_stream_get_latency).

Don't leak srcpad if there are no caps.

Clients can configure the desired behaviour via "transport" property. The
default behaviour is ignoring the transport state. Other modes are master and
slave.

wavenc only accepts little-endian PCM, but most of our
elements such as audiotestsrc only produce or process
audio in native endianness, so we need to plug a
converter before wavenc on big endian systems.

When qjackctl is started, transport is stopped by default. This would be a
regression for gstreamer apps that before just started to play right away.

This feature allows to start and stop playback from other jack applications (e.g. qjackctl).
