libusbgx: Add internal API for defining function types

Browse source 
Adding support for a new function type was quite complicated.
Moreover the main library source fail was growing realy fast.

As a solution introduce internal OO API for defining function.
Thanks to this support for each function may be placed in
a separate file.
