Log latency infos for portaudio input/output and sdl output

Related to #576 and #573

The additional/modified logging itself is fine, but when I try to git apply it locally I get a bunch of warnings about trailing whitespace:

[bbq@luna USDX]$ git apply 575.patch
575.patch:38: trailing whitespace.
    Log.LogStatus('Latency of ' + deviceInfo^.name + ': ' + 
575.patch:39: trailing whitespace.
                  floatToStr(StreamInfo^.inputLatency * 1000) + 
575.patch:40: trailing whitespace.
                  'ms (requested: ' + 
575.patch:41: trailing whitespace.
                  floatToStr(inputParams.suggestedLatency * 1000) + 
575.patch:55: trailing whitespace.
  Log.LogStatus('Audio-Output Latency: ' + floatToStr(Latency * 1000) + 
warning: squelched 3 whitespace errors
warning: 8 lines add whitespace errors.

I'm not sure if the warnings are a git thing or it picks up some editor thing somewhere, but either way the end of line whitespace is a bad idea. Could you remove those?
Ideally also rebase it against a current master, the CI has undergone quite some changes since this PR was opened.
