Move to libpldm pldm_transport APIs

- Replaced the deprecated pldm transport APIs with the new libpldm
  pldm_transport APIs.

This change migrates the application off of the deprecated "requester"
APIs in libpldm.

We don't currently have the infrastructure in place to get the correct
TIDs, so to keep everything working as before use the EID as the TID in
the EID-to-TID mapping.

OpenPOWER OCC Control Service

This service will handle communications to the On-Chip Controller (OCC) on Power processors. The OCC provides processor and memory temperatures, power readings, power cap support, system power mode support, and idle power saver support. OCC Control will be interfacing with the OCC to collect the temperatures and power readings, updating the system power mode, setting power caps, and idle power save parameters.

The service is started automatically when the BMC is started.

Build Project

This project can be built with meson. The typical meson workflow is: meson builddir && ninja -C builddir.

Server

The server will start automatically after BMC is powered on.

Server status: systemctl status org.open_power.OCC.Control.service

To restart the service: systemctl restart org.open_power.OCC.Control.service

Configuration

Service files are located in service_files subdirectory.
