    Linux: fix sysfs directory handling
    
    The length of the directory name varies, e.g. when you have nested hubs.
    Use dynamic allocation to be able to deal with any length of name.

    Linux: correct usage of MAX_PATH
    
    Thanks to clarification from Artem Egorkine, MAX_PATH already includes
    space for the trailing NULL.

    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.

    Linux: Compatibility with new sysfs descriptors file
    
    As of 2.6.26, the descriptors file now includes all descriptors, not
    just the active one.

    Introduce contexts to the API
    
    Suggested by David Zeuthen. This allows multiple libraries in the same
    process to independently use libusb without interfering.

    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.

Author: Artem Egorkine <[e-mail]>
Date:   Tue Jun 17 18:27:38 2008 -0500

    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
    specific race conditions and unusual situations.

    round up poll timeout
    
    Pointed out by Richard Röjfors, otherwise we end up busy-looping with
    a poll() timeout of 0.

    libusb_open() returns int instead of libusb_device_handle.

    [dsd: small correction]

commit 2d3a1111caff40ebb87983c861ff548cdc9e5946
Author: Daniel Drake <[e-mail]>
Date:   Thu May 29 17:26:26 2008 +0100

    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.

commit 514bb8790cfe8b93ccfff82bc17081b1030acce0
Author: Daniel Drake <[e-mail]>
Date:   Thu May 29 12:35:01 2008 +0100

    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.

Date:   Sun May 25 22:59:09 2008 +0100

    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

commit 7c525480ab3c4db9205bfe30bb0d2bef9096c444
Author: Daniel Drake <[e-mail]>
Date:   Fri May 23 15:57:07 2008 +0100

    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.

    allow LIBUSB_DEBUG env var to control message verbosity at runtime
    
    Based on ideas from Ludovic Rousseau

    don't print messages by default
    
    Add libusb_set_debug() API to set message verbosity.
    
    Ludovic Rousseau pointed out that applications may close stdout/stderr
    descriptors, which might then be reused.

    Fix memory leak in libusb_control_transfer
    
    Pointed out by David Engraf: we weren't freeing the transfer buffer

    Linux: fix handling of ioctl failure
    
    The return value of some ioctl commands in linux_usbfs.c are not
    handeled correct. The ioctl function returns != 0 and errno is set with
    the error code.

    critical memory leak in handle_events
    
    This patch closes a critical memory leak in handle_events. The fds
    variable is malloced but never freed. When I'm calling
    handle_events with a timeout of 0, my system runs out of memory after a
    few seconds.

    Fix endianness with descriptor handling
    
    Alan Stern pointed out that usbfs gives host-endian data, but sysfs gives
    bus-endian.

    Linux: fix bulk transfer early completion
    
    We were forgetting about the remaining urbs when a non-final urb
    completed early.
    
    [dsd: some touchups and a warning message for a corner case that we don't handle]

    Handle hot-unplugging
    
    This involved moving from select() to poll() because there is no way to
    distinguish usbfs's POLLERR condition with select().

    Endianness of control setup packets

    used respectively.
    
    Also remove packed attribute from libusb_control_setup as all fields
    are naturally aligned.

    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.
