new modules 'posix_spawn', 'posix_spawnp', 'spawn', 'sched'

[Bruno Haible]

Hi,

I've added a port of GNU libc's posix_spawn facility to gnulib. With this,
you can use posix_spawn portably on all Unix platforms (not yet on mingw).

The main modules are:
  - posix_spawn: spawn a subprocess
  - posix_spawnp: likewise, looking up the program in $PATH
  - spawn: <spawn.h>
  - sched: a minimal / dummy <sched.h>.

There are also additional modules, one for each accessor function.

The patch is not attached to this mail; please review it here:
