But still keep customized iptables because the newer version of iptables would
result in very big range of package upgrading due to dependence relationship.
Also add newer version of "virt-what" from debian testing, otherwise it would
provide wrong information for xen-domU(reported as xen-dom0 in previous version
for 2.6.39). This one have no dependency issue and can be added easily.

Summary of Changes:
while adding a primary address to the domR interface, previous primaray addresses(ip) are removed and added as with 32-bit netmask.
This is to avoid two same ip's with different netmask attached to the interface.
The following are summary of changes:
1) when network.disable.rpfilter is set to true, then rp_filter will be disadbled(set to 0) on all the public interfaces and also default setting of the system.
2) when network.disable.rpfilter is set to false, then rp_filter will be enabled(set to 1) on all the public interfaces and also default setting of the system.
3) here public public interface means , eth2 ... ethN. default setting means (/proc/sys/net/ipv4/conf/default/rp_filter).
4) Default setting change will have impact on non-public interface. Due to these, rp_filter is always enabled on Non-public interfaces(eth0,eth1 and lo).
5) when a new public interface is created, new interface will take rp_filter value from the default setting.

2) here public public interface means , eth2 ... ethN. default setting means (/proc/sys/net/ipv4/conf/default/rp_filter).
3) Default setting change will have impact on non-public interface.if there is no specific setting for other interfaces in /etc/sysctl.conf or otherexplict setting , they will follow this default settings. currently non-public interface like eth0 ,eth1 does not have any specific setting in sysctl.conf, due to this there rp_filters will be changed when ever network.disable.rpfilter setting is changed.
4) default setting is required to changes beacuse when a new public interface is created, new interface will take rp_filter value from the default setting.
Because currently the lock in the script is retried every 1 second, and it's a
quite a long time that it's possible for some other active script can be
executed and retain the lock again. So it's possible that the first one request
the lock is always being preemptted by others, then finally got timeout.
To fix this issue, the retry interval is reduced to 0.1 seconds, which would
provide more retry times. And each process want to get the lock would create a
file named lockname-PID.lock, and only the first one(judged by timestamp) would
get the lock. The remaining ones would retry every 0.1 seconds to see if it can
get the lock.
Also timeout time is extended to 30 seconds.
And add testcase for it.

To solve password file is destroyed along with restartNetwork command issue. If
the password is not set in fact, user can use "ResetPassword" to try again. But
it won't happen mostly, because it's only possible if the restartNetwork
happened between user start up VM and set the new password.

Added New value "link-local" to global config network.loadbalancer.haproxy.stats.visibility . With this change it can take new parameter "link-local" value apart from the existing 3 values global,guest-network,disabled.
global - stats visible from public network
guest-network - stats visible only to guestnetwork.
link-local - stats visible only to link local network
disabled - stats disabled.
Added global config to enable/disable rp_filter for domR.

Test Case-1 :
1) Set network.disable.rpfilter global config to true
2) Restart the domR
3) check the settings reflected in proc filesystem
- for public interface like eth2,eth3 : /proc/sys/net/ipv4/conf/eth2/rp_filter should have 0 , and rest other interfaces should have value of 1
Test Case-2 :
1) set network.disable.rpfilter global config to false
2) Restart the domR
3) check the settings reflected in proc filesystem
- for public interface like eth2,eth3 : /proc/sys/net/ipv4/conf/eth2/rp_filter should have 1 , and rest other interfaces should also have value of 1
This message may show during redundant router start up:
FAULT (Restarting DNS forwarder and DHCP server: dnsmasq failed!)
This caused by edithost.sh is racy with keepalived process. They both want to
restart dnsmasq.
Even in normal condition, it's very hard to reproduce this bug. Add file lock
for edithost.sh should solve it.
