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.

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.

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.

Also, CLOCK_MONOTONIC_RAW seems even more monotonic, so we should use
that if it is available.

best one that works.

synchronous such that control is not returned until the transfer
definitively succeeds or fails.  That assumption is violated if a signal
