Linux: Fix #81 URB double free race condition on device disconnect

picked up by an event handler to be cleaned up, where freeing of URB

libusb_submit_transfer() always holds itransfer->lock, so the race can

needed to call a libusb_handle_events() function. However, the check
was done outside of the lock that is held while the condition is set,

error, but with significant delay.

Linux: Stop kernel from re-attaching in-kernel driver after reset

When an interface is bound to the usbfs driver (iow claimed), the
kernel will unbind it, and then after the reset do a device_attach
on the interface, which will bind the default in kernel driver to
the interface.

So if an app has detached the in kernel driver, and claimed the
interface and then does a libusb_reset_device. Things end up with
the interface no longer being bound to the usbfs driver (so no longer
claimed) and instead it is bound to the in kernel driver (iow the in
kernel driver is re-attached).

We can stop this from happening by releasing all claimed interfaces
before the reset, as the kernel will not do the device attach after
reset, if no driver was bound to the interface before the reset.

Linux: Fix #70 race condition in sysfs_get_device_list()

Change the way libusb chooses between using sysfs and usbfs for information
about the attached devies.  Using the old method, a race condition could
occur if a device was unplugged just before (or during) the call to
libusb_get_device_list(), corrupting the internal sysfs_can_relate_devices
and sysfs_has_descriptors variables and preventing libusb_get_device_list()
from working in future calls.

The old method was based on the assumption that if certain sysfs files
(eg: busnum) could not be opened, that indicated an inadequacy of sysfs
(ie: the running kernel's sysfs version did not contain those files),
when in reality those files couldn't be opened because the device had
been unplugged.

The new method checks the adequacy of sysfs during libusb_init()
(op_init()) and if a sysfs file cannot be opened, it is now assumed that
it is because the device has been unplugged, not because sysfs is
inadequate.
