USBDEVFS_DISCARDURB IOCTL call expects a pointer to the
the urb structure to be passed from userspace. LibusbHost
instead sends usbdevfs_urb**. Change this to usbdevfs_urb*.

libusbhost can handle multiple inotify events at same time on Kit kat.
In original implementation, the function-level ret is assigned with
length of read and used for while loop.
if want to add a new watch for subdirectory,inotify_add_watch will
update the function-level ret with watch descriptor.
It impact on while loop to do exit.
Add local result to avoid it.

On some devices there is a slight delay between the creation of "/dev/bus"
and "/dev/bus/usb". Previously, the code assumed that both are created in the
same time which caused "watch_existing_subdirs" to fail and libusbhost to stop
working until the device is rebooted. The fix will setup an inotify event on the
creation of the "bus/usb" so it will not be missed once it's created.

due to limitations of the droidboot OS used for POS,
there's a need for a static libusbhost library.
this permits to include libusbhost in droidboot

Modify libusbhost to expose the inotify watch descriptor to clients
This modification permits clients to add the watch descriptor to
their polling loop so that they don't have to use a dedicated
thread only for libusbhost.

On some devices, /dev/bus/usb does not exist on boot, it is only created
when the otg port is in host mode. Use inotify to detect when /dev/bus/usb
is created and then start watching subdirectories.

When a new bus is added, check for existing devices in the bus
directory, since devices may have been added before calling
inotify_add_watch.
Also add missing inotify_rm_watch calls.

This can be used to ask the kernel to disconnect its driver for a device
so usb_device_claim_interface() can claim it instead.
Also increased size of descriptor buffer and added some debugging logs
