Modified files:

sys/kern kern_descrip.c sys_pipe.c sys_socket.c
uipc_syscalls.c vfs_syscalls.c
vfs_vnops.c
sys/sys file.h
Log:
Fix fd race conditions (during shared fd table usage.) Badfileops is
now used in f_ops in place of NULL, and modifications to the files
are more carefully ordered. f_ops should also be set to &badfileops
upon "close" of a file.
This does not fix other problems mentioned in this PR than the first
one.
