Peter M. Groen / openhantek

OpenSUSE uses rpm packages but it's not a RHEL derivative, their packages have different names so the current instructions are wrong for OpenSUSE users.

This change fixes the issue.

I've successfully built openhantek on OpenSUSE Tumbleweed and it works with a Hantek 6022BE.

…encies to build.md doc

…ported models. A new model now only needs a h/cpp file and of course missing protocol commands

* Add new feature flag "isFixedSamplerateDevice" and a new "fixedSampleRates"
  vector for fixed sample rate devices.
* Add "specialTriggerChannels" to the device specifications and remove it from
  hantekdsocontrol.
* Correct constness mistakes
* Convert BulkCode to enum class. All (uint8_t) conversions need to disappear
  with a second refactoring round, when the command and commandPending field
  will be redone.

Bigger picture:
 - The hantekdsocontrol class should not differentiate on specific model commands.
 - Get rid of the switch in HantekDsoControl::setTriggerSource
 - Unite HantekDsoControl::"command" and "commandPending" by adding a
   pending flag to the new BulkCommand class.
 - Unite HantekDsoControl::"control" and "controlPending" by adding a
   pending flag to the new ControlCommand class.
 - Get rid of HantekDsoControl::"controlCode"

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
