Rickslab-gpu-utils

* Significant bug fixes and error proofing. Added messages to stderr for missing driver related files.
* Added fan monitor and control features.
* Implemented --no_fan option across all tools. This eliminates the reading and display of fan parameters and useful for those who have installed GPU waterblocks.
* Implemented P-state masking, which limits available P-states to those specified. Useful for power management.
* Fixed implementation of global variables that broke with implementation of modules in library.
* Added more validation checks before writing parameters to cards.

* Many bug fixes!
* First release of amdgpu-pac.
* Add check of amdgpu driver in the check of environment for all utilities. Add display of amdgpu driver version.
* Split list functions of the original amdgpu-monitor into amdgpu-ls.
* Added --clinfo option to amdgpu-ls which will list openCL platform details for each GPU.
* Added --ppm option to amdgpu-ls which will display the table of available power/performance modes available for each GPU.
* Error messages are now output to stderr instead stdout.
* Added power cap and power/performance mode to the monitor utilities. I have also included them in the amdgpu-ls display in addtion to the power cap limits.

* Added *--pstates* feature to display table of p-states instead of GPU details.
* Added more error checking and exit if no compatible AMD GPUs are found.

* Completed implementation of the GPU Monitor tool - *amdgpu-monitor*
