hotplug: Improve internal structure and deregistration mechanism
This commit shrinks the size of the internal hotplug callback structure
by removing unused fields, using the correctly sized types for matching
fields, and adding a new flags field whose bits control how the callback
structure should behave.
The hotplug callback handle ID counter has also been moved to the
context structure instead of being a global variable shared amongst all
contexts. This lets each context independently manage handle IDs and use
the maximum range of possible IDs.
Finally, the hotplug callback deregistration mechanism has been improved
to signal to the event handler that an explicit deregistration needs to
be handled. This removes the need to send a dummy hotplug message, which
was using an invalid libusb_hotplug_event value anyway that was causing

core: Improve robustness of event handling
Prior to this commit, it was possible on Linux to poll a file descriptor
that was not valid for libusb. This could happen given the following
sequence of events:
1) Application registers hotplug callback
2) Application calls into libusb to handle events
3) USB device is unplugged, triggering hotplug event
4) Event handling thread calls registered hotplug callback
5) Hotplug callback calls libusb_close(), which closes the fd
6) Event handling code retries the poll() call before returning
At this point, the file descriptor that is being passed to poll() may be
invalid or worse may not belong to libusb at all.
This commit fixes this by removing the code that restarted the poll() call.
It was originally added to allow the processing of multiple hotplug messages
when these messages were delivered across a pipe, but with a linked list now
holding the hotplug messages this is no longer a concern. If any hotplug
messages are present on the list, they are all processed in one pass.

linux: Mark internal file descriptors as CLOEXEC
As a library, libusb should take care to be as friendly as possible
with various use cases. One such way is to ensure that internal file
descriptors have the CLOEXEC flag set, thus allowing processes to do
a fork() + exec() without leaking libusb's file descriptors to the
child process.

core: Remove use of gettimeofday()
Prior to this commit, gettimeofday() was being used for timestamps
in debug messages. This function has been marked as deprecated in
the latest POSIX specification and furthermore is not supported on
Windows, thus requiring our own implementation as usbi_gettimeofday().
This commit changes the logging code to obtain timestamps using the
clock_gettime() function provided by the backend. The implementation of
usbi_gettimeofday() for Windows was actually equivalent to that of the
USBI_CLOCK_REALTIME implementation for clock_gettime(), so this
eliminates code duplication. In addition, the USBI_CLOCK_REALTIME
implementation has been updated for Windows to leverage the
timespec_get() function available in VS 2015 and later.

Fix a race condition with libusb_interrupt_event_handler().
USBI_EVENT_USER_INTERRUPT isn't set in case of another pending event. When
libusb_interrupt_event_handler() is called and USBI_EVENT_POLLFDS_MODIFIED is
already set, but libusb_handle_events() isn't currently active waiting in
poll(), the interrupt request will be cleared before poll() is called. poll()
therefore blocks and the event handler doesn't return.
This is especially the case, when libusb_interrupt_event_handler() is called
before the first call to libusb_handle_events(). In this case
libusb_handle_events() blocks instead of returning immediately.
This patch fixes the race condition by setting the event flag the same way a
