Description of problem:

The http lua-based plugin for vlc allows a remote client to connect to vlc using http queries.  When enabling this plugin, it is necessary to customize the file that defines the access list for remote clients.  This is done by specifying in /usr/share/vlc/lua/http/.hosts the addresses that are allowed to connect.

If one customizes this file, the changes are lost when vlc is upgraded or reinstalled.  The file is simply overwritten, with no backup being made.  As of today, it is necessary to change the access file or put back a saved copy of the file by hand.

The same behavior is true for /usr/share/vlc/lua/http/dialogs/.hosts, and maybe otherconfiguration files.

A reinstall or upgrade should preserve the customized file and create the file from the new package as *.rpmorig.

Version-Release number of selected component (if applicable): 2.0.6-1.mga3


How reproducible:
Always reproducible.  Simply reinstall the plugin or upgrade it.

Steps to Reproduce:
1. Uncomment a line in /usr/share/vlc/lua/http/.hosts, e.g. 192.168.0.0/16
2. Execute: urpmi --replacepkgs vlc-plugin-lua
3. Check that the change was lost, with no backup of the file being made.
