    Linux: enumerate devices and descriptors from sysfs
    
    Suggested by Alan Stern. This avoids waking up any suspended USB devices.
    sysfs is not available on all systems, so the usbfs mechanism is still
    in place as a fallback.

    Linux: fire multiple URBs at once for split transfers
    
    This results in a significant performance increase for bulk transfers
    larger than 16kb, and fixes a bug where data would be spliced and mixed
    between two simultaneously submitted transfers to the same endpoint.
    
    It also allows isochronous transfers larger than 16kb to be submitted.
    
    This commit also improves cancellation - the library now understands
    what is going on.

    Isochronous endpoint I/O
    
    Due to variable-sized structures, this involved changing allocation
    mechanism. All transfers must now be allocated and freed through
    libusb.
    
    A synchronous function is missing, and I could do with writing a few
    more helper functions to simplify things.
