Krzysztof Opasiak 2a0e2bc756 libusbgx: Add functions to set all strs and attrs with one call. 
Rename usbg_create_gadget() to usbg_create_vid_pid().
dd usbg_create_gadget() to allow gadget creation
with given attributes and strings. Add usbg_set_gadget_attrs()
which allow to set all attributes with one call. Add
usbg_set_gadget_strs() which allow to set all strings with
one call.

Gadget structure creation and initialization has been moved to
usbg_create_empty_gadget() to avoid copy-paste same code in
usbg_create_gadget_vid_pid() and usbg_create_gadget().

libusbg-neXt (libusbgx)
-------

libusbgx is a C library encapsulating the kernel USB gadget-configfs
userspace API functionality.

It provides routines for creating and parsing USB gadget devices using
the configfs API. Currently, all USB gadget configfs functions that can
be enabled in kernel release 3.11 (Linux for Workgroups!) are supported.

See the Doxygen docs and examples for complete details on the
programming API and INSTALL for installation of the library and
examples.

To run the examples:

$ mount -t configfs none /sys/kernel/config
$ gadget-acm-ecm
$ show-gadgets
