[fpc-pascal] libusb header translation and OOP wrapper

[Johann Glaser]

Hi!

Some time ago somebody asked about USB support. I've now finished the
libusb 1.0 header translation and object-oriented wrapper.

Please find them at
  https://github.com/hansiglaser/pas-libusb/tree/libusb-1.0
including a few examples to demonstrate the usage.

I've updated http://wiki.lazarus.freepascal.org/Hardware_Access#libusb

I also tried to update my entry in
http://www.freepascal.org/contrib/contribs.html but got a
username/password problem (despite using the same as for the Wiki
above). 

Bye
  Hansi
