Changes applied:
* Moved utility files to /util/.
* Removed unused #includes.
* Removed unused ::ffmpeg::tools function.
* Removed unused variables.
* Fixed missing parentheses in the version macro.
* Fixed missing override on virtual function overrides and removed unnecessary virtual keyword from them.
* Disabled additional warning for ATL headers on MSVC only.
* Replaced direct printf parameters with their macro equivalent.
* Replaced C-style casts with C++-style casts.
* Applied clang-format again after an earlier change to the CMake file broke the integration for it.
* "Quality" Minimum/Maximum is actually QP Minimum/Maximum
* Bitrate Limits is now just Limits
* Buffer Size and Quality Target have been moved into "Limits".
This header includes all common data between headers used in the plugin. This should improve cross-platform compiling support whenever possible, as all platform-dependent common includes and defines can be done here.
* Remove Minimum Bitrate as it is not supported by the encoder.
* Add several default states (-1 or Default) to options.
* Possibly fix bitrate lock with CQP and CQ mode.
* Fix log output for bitrate and B-Frames.
