netcf bugfix update

An updated netcf package that fixes various bugs is now available.

Netcf is a library for modifying the network configuration of a system.
Network configurations are expressed in a platform-independent XML
format, which netcf translates into changes to the system's 'native'
network configuration files.

This update rebases netcf from version 0.1.6 to the current upstream
version, 0.1.7. (BZ#651032)

This rebase addresses several issues, including:

* Tight coupling between netcf and gnulib

* Disallowing firewall rules editing

* An iptables rule tweak regarding tuneable kernel necessity

This re-base also incorporates fixes for two bugs as follows:

* Previously, after a reboot, virInterface functions did not work until
libvirt was restarted and instead failed with a "error: Failed to list
active interfaces. error: this function is not supported by the
connection driver: virConnectNumOfInterfaces" error message. This is
now fixed so that the code that caused the problem is removed and
virInterface functions operate as expected after a reboot. (BZ#633346)

* Previously, netcf was unable to initialize due to the system's iptables
configuration and failed with a "Failed to initialize netcf. error:
unspecified error" error message. This is now fixed and netcf no longer
fails during initialization. (BZ#629206)

Users are advised to upgrade to this updated package, which resolves
these issues.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
