b47db27181 Added paInt16, paInt8, format using new "pa_common/pa_convert.c" file. 
Return error if opened in mono mode cuz not supported.
Add support for Pa_GetCPULoad();
Fixed timestamp in callback and Pa_StreamTime() (Thanks n++k for the advice!)
Check for invalid sample rates and return an error.
Check for getenv("PA_MIN_LATEWNCY_MSEC") to set latency externally.
Better error checking for invalid channel counts and invalid devices.

f4158d9008 If watchdog detects canary getting starved, then just lower audio thread 
priority instead of killing it. If audio completely hung then still kill it.

7e73ac614d Fixed the nonblocking open - now it tries to open each device in 
nonblocking mode, and if that succeeds, closes it and opens it
again in blocking mode - and added a new Pa_StreamTime
implementation that uses SNDCTL_DSP_GET[I/O]PTR.

5f6b6644dd Added O_NONBLOCK to all open() calls, so that PortAudio 
does not hang if the device is in use by another program.

03fca8ce5d Mods made with Darren Gibbs. 
fixed isInput so GetProperty works better,
fixed device queries for numChannels and sampleRates,
one CoreAudio device now maps to separate input and output PaDevices,
audio input works if using same CoreAudio device (some HW devices make separate CoreAudio devices).
