Rewrite get_process_open_files() in C for OSX

Patch in attachment reimplements get_process_open_files() in C on OSX instead 
of parsing lsof output.

Before:
real    0m0.420s
user    0m0.137s
sys     0m0.267s

Now:
real    0m0.144s
user    0m0.082s
sys     0m0.056s

That's about 3x faster and far more reliable than current implementation.

It seems kinfo_getfile() is not available on FreeBSD versions < 8.0.
I think we can use kvm_*() calls instead, but I'd rather plan to do this in a 
future version.
As for now I'm going to revert this change and fall back on using lsof 
implementation.
