Modified Files:
        src/sys/kern: kern_exec.c

Log Message:
More posix_spawn fallout:
Fix a kmem_alloc() call with zero size (PR kern/46038), allow file actions
to be passed, even if empty.
Rearange p_reflock locking for the child, avoid a double free in an
error case, avoid a memory leak in another error case - all pointed out
by yamt.
During blocking operations early in the child borrow the kernel vmspace
(as suggested by yamt).
