    Linux: don't set SHORT_NOT_OK on bulk out URBs (#20
    
    Setting this flag is illegal, and the behaviour we're looking for
    is already in place for host-to-device transfers without this flag.

    Linux: correct config descriptor endianness fix
    
    The seek_to_next_config codepath deals with both sysfs and usbfs;
    make sure we only convert values in the usbfs path.

    Linux: Fix endianness handling of usbfs config descriptors (#27)
    
    driver/usb/core/devio.c function usbdev_read translate the follwing files
    to CPU endianess:
    
    le16_to_cpus(&temp_desc.bcdUSB);
    le16_to_cpus(&temp_desc.idVendor);
    le16_to_cpus(&temp_desc.idProduct);
    le16_to_cpus(&temp_desc.bcdDevice);
    
    All other data is passed without any change.
    
    libusb/os/linux_usbfs.c calls usbi_parse_descriptor with host_endian=1
    for config descriptors. According to the kernel code, they must be
    processed with host_endian=0, as they are not translated by the kernel.

    Use timerfd for timeout handling
    
    Use a new file descriptor from the timerfd system calls to handle
    timeouts. On supported systems, this means that there is less hassle
    figuring out when the poll() timeout should be, since
    libusb_get_next_timeout() will always return 0 and the timeout events will
    be triggered as regular activity on the file descriptor set.
    
    Add API function libusb_pollfds_handle_timeouts() to detect whether
    you're on a platform with the timing headache, and flesh out the
    surrounding documentation.

    Linux: Add support for the new URB_BULK_CONTINUATION flag
    
    Add support for the new USBDEVFS_URB_BULK_CONTINUATION flag to libusb.
    
    This flag, which is expected to be available in usbfs starting with
    kernel 2.6.32, allows the kernel to cancel multiple URBs upon receipt
    of a short packet.  This capability allows libusb to preserve data
    integrity of large bulk transfers that are split into multiple URBs.
    Without this support, these URBs must be canceled in userspace upon
    receipt of a short packet, a race condition against future transfers
    which might partially fill these canceled URBs.
    
    This patch automatically detects whether a supported kernel is present
    and enables the use of the flag when possible.
    
    [dsd: tweaks to supported kernel detection, and some inline
     documentation of this mechanism]

    Transfer locking
    
    At least on Linux, there were some possible races that could occur if
    a transfer is cancelled from one thread while another thread is handling
    an event for that transfer, or for if a transfer completes while it is
    still being submitted from another thread, etc.
    
    On the global level, transfers could be submitted and cancelled at the
    same time.
    
    Fix those issues with transfer-level locks.

    Linux: more flexibility with monotonic clock
    
    Some users have reported that CLOCK_MONOTONIC does not work on their
    systems - I suspect it is available on x86 but perhaps not some
    of the more uncommon architectures. We should fall back on
    CLOCK_REALTIME in these cases.
    
    Also, CLOCK_MONOTONIC_RAW seems even more monotonic, so we should use
    that if it is available.
    
    We now test different clock IDs during initialization to find the
    best one that works.

    does not consider the number of transaction opportunities per
    microframe.

    Make synchronous transfer APIs robust against signal interruption
    
    libusb_control_transfer and libusb_bulk_transfer are designed to be
    synchronous such that control is not returned until the transfer
    definitively succeeds or fails.  That assumption is violated if a signal
    interrupts these functions because there is no way for the application
    to continue waiting for the transfer without resubmitting it.  This
    patch changes these synchronous APIs so they do not abort in the case of
    a signal interruption.

    Decrement poll() result when internal pipe has been handled
    
    When we receive data on the internal control pipe, we need to correctly
    decrement the number of ready file descriptors before passing on the
    remaining work to the OS implementation.

    Prevent transfer from being submitted twice or improperly canceled
    
    This ensures that tpriv->urbs and tpriv->iso_urbs are always set to NULL
    whenever a transfer is not submitted.  In this way, submit_*_transfer()
    and cancel_*_transfer() can error check to ensure that the transfer is
    in the correct state to be either submitted or canceled, preventing
    potential memory leaks or double frees.

    Linux: Fix race condition in cancel_bulk_transfer()
    
    This fixes a race condition in cancel_bulk_transfer().  In the old
    version, awaiting_reap and awaiting_discard are incremented in
    cancel_bulk_transfer() and decremented in handle_bulk_completion().
    However, since these events may take place in two different threads,
    these variables may reach zero before all URBs have been canceled,
    triggered spurious callbacks and duplicate frees.
    
    This changes the logic to use a single variable "num_retired" to replace
    both awaiting_reap and awaiting_discard.  num_retired is incremented
    only in handle_bulk_completion() and thus there is no race.  The handler
    will know that all URBs have been canceled when num_retired becomes
    equal to num_urbs.
    
    This change also simplifies a great deal of the logic in both functions
    and is a net reduction in the amount of code.
    
    Note that some variables such as "reap_action" probably need to still be
    protected by a mutex, and this patch does not address that issue.

    Pause event handling while opening and closing devices
    
    Ludovic Rousseau found that crashes often occur if you close a device
    while another thread is doing event handling.
    
    Fix this by adding an internal control pipe, which the close routines
    use to interrupt the event handler and obtain the event handling lock,
    ensuring that no other thread is handling events while the device is
    closed. After the close completes, it signals all the event handlers
    to start up again using the usual mechanism.
    
    Also modified libusb_open() to do a similar thing, so that event
    handlers are interrupted in order to realise that a new poll fd has
    appeared.

    Temporary workaround for event handling serialization issue
    
    Ludovic Rousseau pointed out that libusb_unlock_events() is not called
    when a thread gets terminated with a signal, meaning that event waiters
    will not be woken up in this case.
    
    Add a temporary hack to libusb_event_handler_active() so that at least
    the other threads will realise on the next iteration of their event
    handling loop.
    
    The real fix will likely involve reworking most of this.

    Refine libusb_set_configuration() semantics
    
    Applications will generally want to set a configuration before claiming
    interfaces. The problem is that the interface may already be set, and
    someone else may have claimed an interface (meaning that all calls to
    set_configuration will fail, even if it's for the same configuration).
    
    There are now 2 options:
    1. Use the new libusb_get_configuration() to determine active
       configuration before calling libusb_set_configuration()
    2. Or just call libusb_set_configuration() as usual, which will do
       nothing if that configuration is already active.

    Rework configuration handling
    
    libusb no longer caches descriptors in libusb_device but backends are
    intended to be able to provide copies from memory. In the common linux
    case we can use sysfs.

    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

    Separate transfer allocation and submission
    
    Leads to some hefty API changes. Now we're much more similar to the
    Linux kernel model.
    
    Problems with dealing with asynchronous control transfers are passed
    on to the user, basically you must allocate a buffer, start with the
    setup, and put the data after. This won't make much sense until
    documented (soon...)

    libusb_transfer is now a kind of transfer handle. To reduce confusion

    Add fallback on /proc/bus/usb
    
    /dev/bus/usb is a relatively new thing probably not present on every
    system

    Persistent libusb_device storage
    
    Devices are now assigned a session ID (currently busnum:devaddr) which
    is used to distinguish unique devices.
    
    Now multiple callers of libusb_get_device_list will get the same
    libusb_device structure instances.

    Add convenience function to find and open a device by USB VID+PID
    
    Lots of libusb apps I write are simple test apps not intended to be real
    apps. Having a function available to quickly locate my device will be
    handy in such situations.

    Rework device discovery API
    
    libusb_find_devices and libusb_get_devices are no more
    
    libusb_get_device_list obtains a list of libusb_device structures for all
    known devices in the system.
    
    Each libusb_device now has a reference count, defaulting to 1 on
    instantiation. The reference count of 1 refers to the fact that it is
    present in the list in this scenario.
    
    Opening a device adds a pointer to the libusb_device structure in the
    handle, so that also adds a reference. Closing the device removes that
    reference.
    
    The function to free the device list can optionally unref all the devices
    inside.
    
    In future we will make the libusb_device instances all "global" so that if
    the app calls get_device_list twice it actually gets the same libusb_device
    structure references back. This way we can start to track disconnects, and
    we can investigate adding a unique "session ID" to each libusb_device, an
    identifier guaranteed to be unique to that device until reboot.

    Remove timers and signalfd
    
    Instead of timers, add a mechanism for informing the parent app when the
    next timeout is due to happen, so that it can call us at that time.
    
    As we no longer use signals, signalfd has also been removed.

    We don't need to use signalfd for this functionality because we can poll
    the file descriptors for write events.

    API renaming: remove fpi and usb_ stuff
    
    fpi changed to usbi.
    
    We should not expose structures with prefix "usb_" in the public
    namespace as it is quite likely there will be some conflict somewhere.
    Instead, using "libusb_" should be safer.

    Don't pass ctrl_msg/bulk_msg structures through async paths
    
    These are easiest to construct on the stack, but in the async case it is
    likely that the submitting function returns (hence stack is destroyed)
    before URB completion.
