fpga_compress: interleave (combine) fpga_lf.bit and fpga_hf.bit before compression.

fpga_loader.c: change to unweave fpga_lf and fpga_hf accordingly
prepare fpga_compress, fpga_loader and Makefile to handle more than two FPGA config files
revert removal of fullimage Makefile target. Remove osimage instead.
