CoreAudio PaStreamCallbackTimeInfo implementation not working in some cases

r1537 added a new implementation of PaStreamCallbackTimeInfo

The implementation is incomplete:

1. inputBufferAdcTime is not computed correctly for all cases (eg full duplex with/without ring buffer).

2. This patch needs to be reviewed for the case where device and AUHAL sample rates differ (ie SRC is used) and if input and output sample rates differ.

See FIXMES in the patch:

I think it would be a good idea to clean up / refactor the logic in the ioProc, possibly with separate io procs for different input/output duplex. At the moment there is a lot of interleaved and dependent if/else logic that makes things very hard to follow.
