Extended fpga plugin to support both in-tree(DFL) and
out-of-tree (OPAE) kernel drivers.
- fpga_crihook: move JSON parsing to separate functions
- decreased cyclomatic complexity of the CRI hook main() function
- increased readability
- increased test coverage

- Migrate to OPAE 1.3.2
- Build all the tools from the source
- ignore files in workspace
- minimal fpga_tool utility to check gbs/aocx file parsing and flashing
- implemented kernel IOCTL based flashing of bitstreams
- add PCI and sysfs functions
Different versions of OPAE tool fpgaconf use different command line
options to specify socket number. Latest version uses -S, which CRI-O
hook used so far.
However, fpgaconf in initcontainer comes from older OPAE version, which
uses -s option for the same purpose. This caused fpgaconf and CRI-O hook
to fail with "Invalid cmdline options".
Used 'fpgaconf-wrapper -s' in the CRI-O hook to fix this.

intel-fpga-initcontainer installs OPAE and OpenCL tools
into /opt/intel/fpga-sw directory.
Used fpgaconf-wrapper, aocl-wrapper and packager tools by
CRI hook to program OPAE and OpenCL bitstreams.
Added support for OpenCL bitstreams: the hook tries to find
either OPAE or OpenCL bitstream suitable for requested region
and AFU and programs it using OPAE or OpenCL tools.
Fixes#71
Check if container annotation com.intel.fpga.mode is set to
"intel.com/fpga-region". This annotation is set by device plugin.
So, the check should help to filter out unwanted workflow that
device plugin is not aware of.
The hook gets FPGA_REGION and FPGA_BITSTREAM environment variables
defined in a pod spec, finds bitstream file, verifies it and programs
FPGA device with it using fpga-configure tool from OPAE.
