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.

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.

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.

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

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...)

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.
