If we have a case where have created a fd for i/o and we have removed the
handling thread but still have the fd in the poll data structure, there
existed a case where we would get the handle this fd return from poll but we
would immediately do nothing with it because we didn't have a thread to hand
the event to.
This leads to an infinite loop. Prevent the infinite loop
from happening and log the problem.

lib: changes for making snmp socket non-blocking
Description: The changes have been done to make the snmp socket
non-blocking before calling snmp_read()
FRR Pull request: https://github.com/FRRouting/frr/pull/5134
Problem Description/Summary :
vtysh hangs on first try to enter after a reboot with BGP dynamic peers
Expected Behavior :
VTYSH should not hang.
When we debug more into bgpd docker by doing gdb on its threads, we find the below thread of bgpd, which is causing the issue.
Thread 1 (Thread 0x7f1e1ec46d40 (LWP 47)):

The fix has been taken from the following link.
https://sourceforge.net/p/net-snmp/patches/1348/
* [sonic_platform]remove the handling of reset_sw_reset which indicates rebooted by software.
* [sonic_platform]Check "reset_sw_reset"
Also check reboot cause file "reset_sw_reset" which indicates the system was rebooted due to software requesting.
The owner of the generated files (/etc/frr/*.conf) by start.sh is root if it is a new file.
This will cause error when executing "copy running-config startup-config" in vtysh because of privilege issue.

From 5.1 version of PyYAML python module, yaml.load() API is deprecated. Code should be compatible to support both the versions, else error/warning messages are seen like below,
2019-07-02 08:25:35,284 – INFO: [D1] /usr/local/lib/python2.7/dist-packages/sonic_device_util.py:44: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
In teamd v1.28, the port can only be enabled if sync bit is set
in recveived LACPDU from partner by the following commit
"teamd: lacp: update port state according to partner's sync bit"
(54f137c105)
However, lacp fallback feature needs to enable port even if partner
LACPDU is not received within a given period and fallback cfg is enabled.
To fix the lacp fallback breakage, we have to bypass the sync bit
check in lacp fallback mode.

While doing CLI changes for SNMP configuration, few changes are made in backend to handle the modified CLI.
** Changes**
- "community" for "snmp trap" is also made as "configurable". snmpd_conf.j2 is modified to handle the same.
- Changed the snmp.yml file generation from postStartAction to preStartAction in docker_image_ctl.j2 specific to SNMP docker, to ensure that the snmp.yml is generated before sonic-cfggen generates the snmpd.conf.
- Changed to make the code common for management vrf and default vrf. Users can configure snmp trap and snmp listening IP for both management vrf and default vrf.

The script sonic-gns3a.sh creates a GNS3 appliance flle, that points to a sonin-vs.img (SONiC Virtual Switch).
The appliance file (and sonic-vs.img file) can subsequently be imported into a GNS3 simulation environment.
Adjust the SDK makefiles so that it reflects the dependencies among libraries in SDK 4.3.2104.
This is a supplement of PR [Mellanox]Update SDK(4.3.2104), SAI-Implementation(1.15) and firmware 2162. It doesn't impact the sonic-mellanox.bin image but makes the future SDK-integration easier.
- after reloading minigraph, write latest version string in the DB.
- if old config_db.json file exists, use it and migrate to latest version.
- only reload minigraph when config_db.json doesn't exist and minigraph
exists.
