* Alternate email is correo@fernando-ruiz.com
* libc/privateenv.c: New file.
* include/rtems/libio_.h, libc/Makefile.am, libc/base_fs.c,
libc/unmount.c: Moved default umask, current working directory,
root, and links followed count into a structure "user environment"
that can then be treated as a unit. This enable giving unique
copies of these to individual threads or collection of threads.
