FreeBSD quarterly status report Q2 2017

Much of the development work done this quarter was not particularly visible, especially the effort needed to ensure the upcoming 11.1 release has as few regressions as possible. Planning is also well under way for the 10.4 maintenance release which will quickly follow it.Further work focused on moving the arm architectures' support closer to tier-1 status and improving documentation. In addition, large changes were made to the src and ports trees.
