        sys/kern/kern_exec.c: revision 1.344
Posix spawn fixes:
- split the file actions allocation and freeing into separate functions
- use pnbuf
- don't play games with pointers (partially freeing stuff etc), only check
  fa and sa and free as needed using the same code.
- use copyinstr properly
- KM_SLEEP allocation can't fail
- if path allocation failed midway, we would be possibily freeing
  userland strings.
- use sizeof(*var) instead sizeof(type)
fix fae free'ing, from enami.
keep track of the original array length so we can pass it to kmem_free, from
enami
