This update for sysconfig contains the following fixes:

- sysconfig hook script for NetworkManager did not properly
quote shell meta characters when processing ESSIDs.
Specially crafted network names could therefore lead to
execution of shell code (CVE-2011-4182).
- Explicitly disabled posix mode in all bash scripts as we
are using several features not supported in posix mode
(bnc#739338).
- Fixed ipv6 dad / link ready wait time calculation (1/10
of the specified time were used), replaced useless up
flag check loop with link_ready_wait to avoid send
errors from dhclient6 and cleaned up link / dad wait
verify flag after status update (bnc#697929).
