Improving OpenJDK for FreeBSD

[Thomas Stüfe]

Hi Harald,

In addition to what David wrote:

- PPC changes: we already deal with AIX and Linux, and adding BSD is
getting a bit #ifdef heavy. I wonder whether we should factor certain
things out into (aix|bsd|linux)_ppc.cpp. For example, all of these os/cpu
combinations use the same register set, but the ucontext is different for
every one of them, so a utility function like `get_gpr_from_context(const
ucontext_t* c, int num)` would help. Ultimately, that is up to Martin as
ppc lead (I set him on cc).

- the bigger issue to me is the amount of large ifdef sections added to
os/bsd and bsd/<arch> : I think its time to separate MacOS from BSD and
make both first-class OSes. The amount of duplicate coding would be
outweighed by clearer code. Up for discussion, of course; that is just my
gut feeling right now.

Cheers, Thomas
