    cpu: Add CPU information to pa_core
    
    This retains CPU information (processor type and supported features) in
    pa_core, so that this information can be used by modules at init time to
    figure out what optimisations may be used.

    echo-cancel: Add SSE optimisation to the adrian module
    
    Optimises the core inner-product function, which takes the most CPU. The
    SSE-optimised bits of the adrian echo canceller only if the CPU that PA
    is running on actually supports SSE.

    echo-cancel: orc-ify some bits for optimisation
    
    This uses Orc to optimise an inner loop in the core NLMS function of the
    Adrian echo canceller.

    echo-cancel: Ensure correct handling of endianness
    
    The adrian module was using home-brewed endianness conversion instead of
    the appropriate mactos, and speex assumed a little-endian host. This
    fixes both of these.
