As per the VOQ HLDs, internal networking between the linecards and supervisor is required within a chassis.
Allocating 127.X/16 subnets for private communication within a chassis is a good candidate.
It doesn't require any external IP allocation as well as ensure that the traffic will not leave the chassis.

https://github.com/Azure/SONiC/pull/622https://github.com/Azure/SONiC/pull/639
**- How I did it**
Changed the `interfaces.j2` file to add `127.0.0.1/16` as the `lo` ip address.
Then once the interface is up, the post-up command removes the `127.0.0.1/8` ip address.
The order in which the netmask change is made matters for `127.0.0.1` to be reachable at all times.
**- How to verify it**
```
root@sonic:~# ip address show dev lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/16 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
```

Refactor SFP reset, low power get/set API, and plugins with new SDK SX APIs. Previously they were calling SDK SXD APIs which have glibc dependency because of shared memory usage.
Remove implementation "set_power_override", "tx_disable_channel", "tx_disable" which using SXD APIs, once related SDK SX API available, will add them back based on new SDK SX APIs.

This change introduce the rules/config.user file.
It gets loaded after rules/config as a mean to override default values.
If the configuration file does not exists this step is ignored.
Since this path is tracked by .gitignore, it provides a mean to change
the configuration of sonic build without dirtying the git tree.

Most of the devs know how they configured their build.
Instead of generating a huge header for every make operation, allow the
user to silence it via an environment variable.

When BGP routes are missing, DHCP packets get relayed over mgmt
interface. This results in dhcpmon alerting that DHCP packets are
not being relayed. This is PR include mgmt interface as uplink
device, and so, if DHCP packet gets relayed over mgmt interface,
regular dhcpmon alert will not be issues. Instead, dhcpmon will
check the mgmt interface counts and issue a separate alert regarding
packets travelling through mgmt network.
In addition, this PR includes the following enhancements:
1. Add SIGUSR1 handler that prints out current packet counts
2. Increase alert grace window to 3 minutes from currently 2 minutes
3. Time is now computed more accurately
4. Print vlan name before counters

This is due to the number of programs in the container managed by supervisor, all generating events at the same time. The default event queue buffer size in supervisor is 10. This patch increases that value in all containers in order to eliminate these errors. As more programs are added to the containers, we may need to further adjust these values. I increased all buffer sizes to 25 except for containers with more programs or templated supervisor.conf files which allow for a variable number of programs. In these cases I increased the buffer size to 50. One final exception is the swss container, where the buffer fills up to ~50, so I increased this buffer to 100.

This PR addresses fixes in sonic-py-common to imitate the behavior inside

and then for legacy port_config.ini.

Remove radvd Makefile and patch, change docker-router-advertiser Dockerfile template to simply install the vanilla radvd package using apt-get.
- In PR https://github.com/Azure/sonic-buildimage/pull/2795, we started building radvd from source and patching it to prevent it from erroring out when advertising an MTU of 9100 which was greater than the MTU size configured on the bridge interface (1500), which was due to a limitation in the 4.9 Linux kernel.
- Master branch is now using Linux kernel 4.19. As of 4.18, the kernel supports setting a bridge MTU to a value > 1500.
- PR https://github.com/Azure/sonic-swss/pull/1393 modified vlanmgrd to take advantage of this and now configures the MTU of bridge interfaces in SONiC to the proper size of 9100. Therefore, we no longer need to patch radvd. Since we no longer need to patch radvd, we no longer need to build it from source, so we can save build time by going back to simply installing the vanilla radvd Debian package in the router-advertiser container.
Copying platform.json file into an empty /usr/share/sonic/platform directory does not mimic an actual device. A more correct approach is to create a /usr/share/sonic/platform symlink which links to the actual platform directory; this is more like what is done inside SONiC containers. Then, we only need to copy the platform.json file into the actual platform directory; the symlink takes care of the alternative path, and also exposes all the other files in the platform directory.
sonic-py-common package relies on the `PLATFORM` environment variable to be set at runtime in the SONiC VS container. Exporting the variables in the start.sh script causes the variables to only be available to the shell running start.sh and any subshells it spawns. However, once the script exits, the variable is lost. This is resulting in the failure of tests which are run in the VS container, as they call applications which in turn call sonic-py-common functions which rely on PLATFORM to be set.
Setting the environment variables in the Dockerfile allows them to persist through the entire runtime of the container.
