 Rework posix_spawn locking and memory management:
  - always provide a vmspace for the new proc, initially borrowing from proc0
    (this part fixes PR 46286)
  - increase parallelism between parent and child if arguments allow this,
    avoiding a potential deadlock on exec_lock
  - add a new flag for userland to request old (lockstepped) behaviour for
    better error reporting
  - adapt test cases to the previous two and add a new variant to test the
    diagnostics flag
  - fix a few memory (and lock) leaks
  - provide netbsd32 compat
 Fix asynchronous posix_spawn child exit status (and test for it).
