commit 0a4a9c77c8050921de07a2085cd6de5fe83db343

file descriptor enumeration - Fix races
Add a soft refrence count, fd_softrefs, to struct filedesc. This is
used to prevent the filedesc from being ripped out from under a file
descriptor scan via the allproc scan, which is used to enumerate
file descriptors and also used by the revoke code.
