Windows: Rework poll() emulation to a much simpler and effective design
The previous poll() implementation worked okay but had some issues. It
was inefficient, had a large footprint, and there were simply some use
cases that didn't work (e.g. a synchronous transfer that completes when
no other event or transfer is pending would not be processed until the
next poll() timeout).
This commit introduces a new, simpler design that simply associates an
OVERLAPPED structure to an integer that acts as a file descriptor. The
poll() emulation now solely cares about the OVERLAPPED structure, not
transfers or HANDLEs or cancelation functions. These details have been
moved up into the higher OS-specific layers.
For Windows NT environments, several deficiencies have been addressed:
1) It was previously possible to successfully submit a transfer but fail
to add the "file descriptor" to the pollfd set. This was silently
ignored and would result in the user never seeing the transfer being
completed.
2) Synchronously completed transfers would previously not be processed
unless another event (such as a timeout or other transfer completion)
was processed.
3) Canceling any one transfer on an endpoint would previously result in
*all* transfers on that endpoint being canceled, due to the use of
the AbortPipe() function.
This commit addresses all of these issues. In particular, run-time
detection of the CancelIoEx() function will allow the user to cancel a
single outstanding transfer without affecting any others still in
process.

Windows: Rework WinUSB enumeration process to fix issues on Win8+
As they sometimes do, Microsoft made changes to the way in which the
SetupAPI functions list the devices returned by SetupDiGetClassDevs().
In particular, composite devices started returning their interfaces
before the parent device, which caused some issues with the way the
enumeration logic was assigning things. For composite devices, it
appears that the first interface behaves much like the parent device in
some regards, so the library was creating a device specifically for the
first interface and then again when the actual parent device was
encountered. This caused composite devices to appear in the device list
twice, with the first instance being unusable for most operations.
This commit significantly changes the way in which the enumeration
process is done. Previously we would scan for HCDs, hubs, and generic
devices, in that order and in distinct passes (obtaining a new listing
of devices from SetupAPI). Now we will obtain a single snapshot at the
beginning of the enumeration process and iterate through this to scan
for each type of device.
With a single snapshot, we can be assured that the device instance
handle will not change between passes and thus we can use this as the
unique identifier. This completely removes the need to hash the device
instance ID to obtain a unique identifier and simplifies the process.
The previous enumeration process also created "dummy" libusb_device
instances for the HCDs that were never exposed to the user. This has
been removed in favor of identifying which of the encountered hubs are
actually root hubs.
Finally, the query for the port number has been moved to the GENeric
pass at the point where the devices are actually initialized. This query
operation has been relaxed to allow failure, since some virtual USB
devices don't properly implement this query in their drivers.

Windows: Improve enumeration process
Prior to this commit, there were some limitations and inefficiencies
during the enmeration process.
First, the maximum number of device interface GUIDs that could be
enumerated was fixed at 64. This limit has been removed and the list
of GUIDs is dynamically resized as new ones are encountered. Logic has
also been added to detect the presence of duplicate GUIDs in order to
speed up the enumeration process.
Next, when searching for device interface GUIDs, only the
"DeviceInterfaceGUIDs" registry key was being consulted. Now we will
also consider "DeviceInterfaceGUID" in order to support devices that
have the GUID listed under this key (such as some WCID devices).
Finally, there used to be a static list of USB PnP enumerator strings
that were used to detect devices during the GENeric enumeration pass. In
many cases, this is wasteful as these enumerators are only present with
very specific hardware. To improve this, we now keep track of the USB
PnP enumerator string encountered as we enumerate the hubs. This allows
the enumeration process to only search for devices that could possibly
be present on the system given the hardware and drivers that were
encountered.

Windows: Kill perpetually growing list of hub driver names
During enumeration, it is unnecessary to match a hub against a list of
known driver names because hubs are enumerated with a specific device
interface GUID. This will eliminate the need for further expansions to
the hub driver list as manufacturers release new drivers.

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
some compilers to complain.

linux_usbfs: Improve isochronous transfer submission and error reporting
The Linux kernel has changed the maximum allowed packet length per
isochronous packet numerous times, which can create difficulties in
trying to report appropriate errors back to the user when submitting too
large of a packet on older kernels.
In an attempt to improve this situation, this commit adds logic that
will use different per-packet limits based on the detected kernel
version. Additionally, the logic has been improved to split URBs based
on the number of isochronous packets per URB, which is currently (and
has been forever) limited to 128.
Finally, the error reporting during URB submission has been improved to
catch and report errors relating to the transfer length being too large.
