>Summary: portaudio fixes for channelnum and samplerate

Initial Comment:
the current portaudio implementation has an issue with the channel selection:
if the user requests more channels than are available for the device, the device will fail to open.

the attached patch, will clamp the requested channels to the number of available channels.

Message:
i forgot to mention: 
the patches also fix the problem if the user requests an illegal
samplerate.
rather than failing to open the device, Pd will now ask portaudio for the
device's default samplerate and use that one.

Message:
there are 2 patches: one for the normal PortAudio code, and one for the
PortAudio-with-callbacks code

both should be applied
