Cyborg is an OpenStack project that aims to provide a general purpose
management framework for acceleration resources (i.e. various types
of accelerators such as GPU, FPGA, NP, ODP, DPDK/SPDK and so on).
It needs some OPAE type APIs to manage PACs (Programmable Acceleration
Card) with Intel FPGA. Below major functions are added to meets
Cyborg requirements.
1. opae_init() set up OPAE environment.
2. opae_cleanup() clean up OPAE environment.
3. opae_enumerate() searches PAC with specific FPGA.
4. opae_get_property() gets properties of FPGA.
5. opae_partial_reconfigure() perform partial configuration on FPGA.
6. opae_get_image_info() gets information of image file.
7. opae_update_flash() updates FPGA flash with specific image file.
8. opae_cancel_flash_update() cancel process of FPGA flash update.
9. opae_probe_device() manually probe specific FPGA with ifpga driver.
10. opae_remove_device() manually remove specific FPGA from ifpga driver.
11. opae_bind_driver() binds specific FPGA with specified kernel driver.
12. opae_unbind_driver() unbinds specific FPGA from kernel driver.
13. opae_reboot_device() reboots specific FPGA (do reconfiguration).

There are called in constructor and destructor, which means all DPDK
applications have this PMD compiled will run above and print some log, is this
really what we want here?
Is there a way to limit the initialize to the PMD context, like 'probe()' etc?
