    Linux: fix reading of active configuration
    
    Shannon Chuang pointed out that we only read 1 byte into an
    uninitialized integer, and then return the whole thing.

    Improvements to multi-threaded I/O system
    
    Documentation brushed up, and I realised that another function is
    needed for tight event handling loops -- they must be able to check
    if an open/close operation is trying to interrupt it.

commit c32aa662769b676ff3247778664fccc71fc427ec
Author: Daniel Drake <[e-mail]>
Date:   Thu Nov 20 15:31:10 2008 +0000

    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.

Author: Aurelien Jarno <[e-mail]>
Date:   Thu Sep 4 13:50:49 2008 +0200

    Support for out-of-tree building
    
    Contrary to libusb 0.1, libusb 1.0 does not support out-of-tree building
    for the documentation part. This patch fixes that by using a
    doxygen.cfg.in file, which contains @top_srcdir@ to refer to the
    location of the libusb source code.

    Reset internal transfer flags on submit

    Linux: fix bulk/iso transfer double-cancellation
    
    Reset counters to 0 so that it's possible to cancel a transfer twice
    without breaking things. Not sure that I want to support this properly,
    but this makes it work at least.

    Revert "Temporary workaround for event handling serialization issue"
    
    This reverts commit 2d3a1111caff40ebb87983c861ff548cdc9e5946.
    This was based on the assumption that dying threads would automatically
    release mutexes, which is not the case.

    a fix for SIGSEGV in handle_bulk_completion()
    
    We cannot dereference tpriv after calling
    usbi_handle_transfer_cancellation() because that function may invoke
    the user-supplied callback which may free the transfer.

    Refine configuration selection again
    
    At Alan Stern's suggestion, just offer the bare "set configuration" and
    "get configuration" functionality, and let applications worry about the

    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.

    Take lock before raising event waiters condition
    
    This avoids a race between the user checking for active event handler
    and then blocking on the condition variable

    Implement serialization of event handlers
    
    Now offers a mechanism to wait for events while another thread is
    doing the event handling. Complicates things for MT async apps, but
    then again it's a bit of a tricky combination to start with.

    critical memory leak in handle_events
    
    This patch closes a critical memory leak in handle_events. The fds

    few seconds.
