Detail: KVM recently got a patch that did away with a few dozen ssh calls
when programming virtual router (CLOUDSTACK-3163), saving several seconds
for each vm served by the virtual router when the router is rebooted. This
patch updates Xen to use the same method, and cleans up the old script refs.

if user changes the VM mac address, all egress packet from the VM will be dropped, but the egress packet still contaminate the bridge cache with fake MAC,
This patch moves the rule to ebtables nat table PREROUTING chain, then the egress packet with modified MAC will not contaminate the bridge cache.

normally, in dhcp reply, the target ip is allocated ip for VM.
but windows 2008 32bit has special field in dhcp reply, which makes dhcp reply use 255.255.255.255 as target ip, which is blocked by SG rule,
createipAlias.sh/deleteipAlias.sh won't be copied to XenServer host.
The directory of the scripts should be ".." rather "../../.." in all the xenserver patches file.
Corrected the path to ".." because the scripts are located at scripts/vm/hypervisor/xenserver/xenserver56/patch
Fixed by updating the patch files that has
entries to copy scipts on xenserver. Here we added
Add-To-VCPUs-Params-Live.sh
Added a check on Host params whether host restricts Dynamic memory control(DMC) to able to allow scale up VM.
If DMC is not enabled then static max and min are set to SO.

This feature enables adding of guest ip ranges (public ips) form different subnets.
In order to provide the dhcp service to a different subnet we create an ipalias on the router. This allows the router to listen to the dhcp request from the guest vms and respond accordingly. Every time a vm is deployed in the new subnet we configure an ip alias on the router. Cloudstack uses dnsmasq to provide dhcp service. We need to configure the dnsmasq to issue ips on the new subnets. Added a new class dnsmasqconfigurator which generates the dnsmasq confg file, this file replaces the old config in the router.
The details of the alias ips are stored in db in the nic_ip_alias table. Every time a new subnet is added one of the ip from the subnet is used to configure the ip alias.
I have pushed the code to https://github.com/bvbharatk/cloud-stack/tree/Cloudstack-702 , also rebased the code with master.
I need to test the code for advanced sg enabled network using kvm.
I have added the unit test
Marvin tests are at https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;h=53e4965
Also accomodated some of the changes suggested by koushik.
corrected the import statements. renamed the IpAlias command to createIpAlias command.
This feature supports only ipv4
Start/stop vm/dhcp server are done. Not done with VM migration.
A new command(PvlanSetupCommand) is sent for setting up PVLAN for vms. Currently
it's focus on OVS implementation. Need to be more abstruct and add vSwitch part.
cause writing the heartbeat to take longer than expected. By comparing
the last successful heartbeat epoch with the current epoch we check if
the timeout value has been met.
Detail: several scripts in the scripts directory weren't marked executable.
Normally this is handled/fixed in the packaging, but harder to deal with in
development environments, so marking them executable.
