Support freebsd

[ja30278]

The only real ugliness here is ENODATA, which doesn't exist on freebsd.

I really want to merge this, but haven't had time to look into it enough yet. Don't lose hope.

[mischief]

fyi openbsd doesn't have ENODATA either. once this is merged i can work on openbsd support.

Just tested this patch, it works.

I pushed a cleaned up version of this as https://github.com/bazillion/fuse/tree/wip-freebsd 9cdcdc4.

I'm not yet 100% convinced of all the details in the code, but more importantly:
the tests don't yet build, because GOOS=freebsd Go has no syscall.Getxattr etc. Is seems /x/sys/unix might have them. I'm working on it.

golang/go#9705

[tv42]

No progress on golang/go#9705 so far, and I'm afraid of merging this without working tests. Apart form that, looks good. If you want to make it happen faster, add Getxattr etc for freebsd to syscallx, on top of https://github.com/bazillion/fuse/tree/wip-freebsd bf5629a.

Looks like golang/go#9705 finally got resolved by cl 6370.

Current status: compiles but tests don't pass. FreeBSD FUSE seems to have way less features, need to skip a bunch of tests.

Basic suppot for FreeBSD went in as 00c7ac3 . I'll be filing issues for the test failures, help appreciated. They'll show up under https://github.com/bazillion/fuse/issues?q=is%3Aopen+is%3Aissue+label%3Aplatform%3Afreebsd
