From: "W. Eric Norum"
I/O redirection from vxWorks startup scripts now works.
Added support for setting NFS server/mount information from PPCBUG argument strings.
rtems_shutdown_executive is now called on IOC exit. On many BSPs this will return control to the bootstrap PROM.
Set POSIX TZ environment variable from NVRAM, or failing that, from EPICS_TIMEZONE.
Cleaned up support for obtaining network configuration from NVRAM.
