bsd-port b58 update

> package package is completely skipped.

> There is a new nio class:

>
> I did not provide a BSD implementation since the Solaris, Linux or
> Windows implementations all use features not present on BSD (/dev/poll,
> epoll, and iocp). Attempting to use this class will result in an
> "platform not recognized" exception until a BSD version is implemented
> (preferably kqueue based).

> There is a new nio package: java.nio.fs. I provided partial/incomplete
> implementation for the BsdFileSystem and BsdFileStore classes. Basically
> I implemented enough so that bsd-port can bootstrap itself on *BSD.
> However, OS X needs an alternate implementation of
> BsdFileSystem.getMountEntries() since OS X doesn't use /etc/fstab like
> the BSD's do. Without an OS X getMountEntries() implementation bsd-port
> can't be used to bootstrap itself on OS X, but it should still build.
>
> The BSD's and OS X currently don't have openat, fstatat, unlinkat,
> renameat, futimesat, fdopendir or getextmntent which are needed for
> full java.nio.fs support. See:
>
> jdk/src/solaris/native/sun/nio/fs/UnixNativeDispatcher.c
>
> I wrote an alternate implementation for getextmntent() that works on
> *BSD but not on OS X. We need alternate implementations for the rest.
> Expect java.nio.fs classes to have problems until we have alternate
> implementations for those functions.
>
> In short, expect bsd-port to have some deficiencies until project
> members or the community provide implementations for the missing
> parts. If you have the interest and capability this is an excellent
> time to contribute to bsd-port.

Good news! BTW, there is now a b59 with a few minor fixes, so probably
worth pulling that in too.  There'll not be much until after JavaOne
so now is a good time to play catch up ;)
