drivers updated

[Jamey Hicks]

I just merged a pull request from Han Wang that adds support for hugetlb pages, enabling portalmem to map 1GB per memory object allocated.

If you pull connectal from git, you will need to update your drivers.

Ubuntu and Debian packages are building now. Upgrading to v15.08.1 or later will update the drivers on x86.

I also updated the drivers in zynq-boot-filesystems in case you do not want to build the Zynq drivers:

    cd connectal; make zynq-drivers
