1a32265b51 spectrum: avoid unneccesary extra fft runs 
Before it was possible that we run an extra fft when the time for sending a new
message is due. Only do this if we have not run the fft for the interval at all.

f1785b0e4a spectrum: only scale the vectors that we are processing 
Phase is not produced by default, so lets not scale it unconditionally to save a
few cycles.

5bf267c485 spectrum: put number of channels to instance variable 
When freeing data the format might have changed. Thus we need to remember for
which format we allocated memory.

b792b100e2 spectrum: use function pointers for data readers 
Don't check the format for each sample frame to read. We can make that decission
in _setup already. This is still not ideal as we call the function per frame.
Ideally we determine how many samples we can copy and have a loop in the input
reader. As an alternative we might also consider to use the fft variants for the
various formats and not convert to float for all cases - we would still need to
mix or deinterleave though.

2738917852 rtspsrc: improve recovery from failed seek 
In case server-side fails to perform seek, i.e. PLAY at non-zero requested
position, recovery so far would arrange for streaming to continue, albeit
having lost position tracking in the process.  So, query position prior
to seek and use upon failed seek.

c622477a92 spectrum: multi-channel support 
Add a boolean multi-channel property with a default of FALSE. When set to TRUE
the element won't mix all input channels to mono, but instead run a FFT on each
channel. In that case the result message would contain a 2 dimensional array
of channel x data for magnitude and phase.

API: GstSpectrum:multi-channel

65f4c4b3e6 spectrum: factor out the code that accumulated samples into the ring-buffer 
Use a separate function to read a sample frame into a ringbuffer slot. In the
future we can use format-specific function pointer to avoid the reoccuring
format checks.

787aca6898 spectrum: add a GstSpecrtumChannel context structure 
We now keep the fft data that is related to one channel in a separate structure
to prepare for multichannel support. We also refactor the code to operate more
often on the channel context.

dd4ec22e7e pulsesink: release pa_shared_resource_mutex before pa_threaded_mainloop_wait 
Not doing so can result in a deadlock when two threads enter
gst_pulseringbuffer_open_device at the same time, as
pa_threaded_mainloop_wait releases the mainloop lock while waiting,
allowing another thread to take it, resulting in a deadlock as two
threads waits for the lock the other is holding.
