Fix SLES10 (and others): highest_userspace_address
- Restored use of highest_userspace_address for accurate value of highest_addr
- posix-mq2 test still failing for SLES10 and RedHat5
- SLES10 and RedHat5 are both Linux 2.6.18
- They use glibc-2.4 and glibc-2.5 respectively
- Ubuntu 9.04 still failing on restart
- Haven't re-tested ARM-32 yet.

Created dl plugin with wrappers for dl{open,close}

Wrappers for dlopen/dlclose don't play well with RPATH. This plugin can
thus be disabled for applications that depends RPATH.

  The user inherits root's fd on the controlling terminal, but cannot
  reopen it.  We now recognize this case, and do 'dup(fd)' on restart.
