Guillaume Ranquet dea46b6657 libusbhost: permits client polling on inotify wd 
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.

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
