Peter M. Groen / openhantek

Add distribution versions to readme

Add opengl header and library reference to the ubuntu build instructions

Fixes #117. Many weak systems run out of resources and finally dead lock when compiled with "make -j"

* Move src/hantek/usb to src/usb
* Move ControlBegin and ControlGetSpeed to src/usb as they are the only protocol structs that are required to make the usb module independently compilable.
* Move hantek protocol specifc structs and enums to src/hantekprotocol
* Rename src/hantek to src/hantekdso
* Refactor all model initalisation specifc code out of hantekdsocontrol into own subclasses inheriting from DSOModel
* Split definitions.h file into controlindexes.h, controlspecification.h, enums.h, states.h
