Fix QuickTime emulated OSErr type.

Browse Source 
The OSErr type on Mac OS X is int16_t, not int32_t (see
http://developer.apple.com/mac/library/documentation/QuickTime/Reference/QTRef_DataTypes/Reference/reference.html).
The upper 16 bits will typically be something random (they're entirely
undefined). Change the type so it's right; a few places tried to compensate
for this by masking out the upper bits, but a few places also missed them,
which made for unpredictable behavior.
