Guillaume Ranquet 08c119910a libusbhost: generates a static library

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.

Benoit Goby f4de078388 libusbhost: Fix USB device discovery on boot
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.

Benoit Goby 6cc883ca09 libusbhost: Fix possible missed "device added" notification
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.

so usb_device_claim_interface() can claim it instead.

Also increased size of descriptor buffer and added some debugging logs
