What does the mutex protect against ? Modifications of opts-

prevents the descriptors from being modified after you

When configfs is integrated, CONFIGFS_ATTR_STRUCT and CONFIGFS_ATTR_OPS
macros should be used, but the latter expects that tere is a to_f_uvc_opts

If the caller of uvc_alloc() does not provide enough
descriptors, binding the function should fail, so appropriate
code is returned from uvc_copy_descriptors().
uvc_function_bind() is modified accordingly to account for possible
errors from uvc_copy_descriptors().

Add support for using the uvc function as a component of USB gadgets composed

convert functions and gadgets to configfs.
I think it could be useful to anyone whishing to use the gadgets.
v1..v2:
- corrected a typo found by Jeremiah
- updated the instruction on how to configure usbserial for generic serial
- patched gadget_serial.txt documentation to reflect the above

The newly added file will be used to provide descriptions of how to test
the functions of USB gadgets.
