Robert Watson a6719c82b1 Push Giant acquisition down into fo_stat() from most callers. Acquire 
Giant conditional on debug.mpsafenet in the socket soo_stat() routine,
unconditionally in vn_statfile() for VFS, and otherwise don't acquire
Giant.  Accept an unlocked read in kqueue_stat(), and cryptof_stat() is
a no-op.  Don't acquire Giant in fstat() system call.

Note: in fdescfs, fo_stat() is called while holding Giant due to the VFS
stack sitting on top, and therefore there will still be Giant recursion
in this case.
