These changes don't access anything above the Darwin/BSD level on Mac OS X, so I am fine leaving the parallel directories left named "bsd".

The changes to hotspot may need to take a slightly different ride into jdk8, so I'd suggest doing that work separately
with the hotspot team.

For everything else, if someone could prepare webrevs of the BSD changes for each repository involved, and send
them to the build-dev at openjdk.java.net alias, we can get reviews started and get the changes integrated.
I have a feeling that as the changes get reviewed we might have some cleanup ideas.
Keep in mind that we cannot and will not just drag over all the changesets in the existing BSD/MAC repositories,
we will need to create fresh, probably large, changesets that identify themselves as BSD or MAC porting
changes. We can create multiple CRs and break it up into separate pieces if necessary.
If you need CRs filed, let me know. So the detailed history and the changesets in the BSD/MAC repositories will
stay with those repositories, just so people understand.

Formally getting BSD builds to happen on a regular basis may be an issue, but first step (in my opinion) is to
get the source code and makefile logic merged in, making sure the existing platform builds are not impacted.
If someone has references to BSD iso images I can at least get started on creating my own VirtualBox setup.

---

I have a major concern here with the build changes involved colliding with our build infrastructure changes
and the jigsaw/modularity changes coming into jdk8.
Right now, jdk8 is basically jdk7 plus a little change, so doing this now may be best, but it needs to happen
quickly, if we wait too long, the merge could be very painful.
