Resubmission of patch for qtsound module including second code review.
major updates:
qtsound is now loaded in one configure option together with qtcapture via --enable-macosx-qtkit.
usage of date_t for timestamp.
raw audio data is not transcoded on the fly, however still needs to be interleaved before passing it on. QTKit doesn't provide interleaved samples; see code comments in Open() for detailed info.
minor updates:
trailing spaces, tabs removed double checked with vi (/\t and /\s\+$)
priority set to 0, short description, temp audio pointers are const, p_demux modified at end, strdup() removed, code lines with no effects removed
other info
concerning objective c and memcpy: the main module and concept have been reused from qtcapture and adapted to work for sound, therefore the same approach concerning memcpy into given buffer.

Description of patch:
This is a first attempt in integrating audio capture functionality into VLC for MAC OS X.
The patch has been tested with Built-in Microphone, Built-in Input and Griffin iMic USB audio system.
This feature can currently only be run seperately. A multiplexed solution with video is not ready yet. Development is still needed here.
