[201911][dockers][supervisor] Increase event buffer size for process exit listener (#7106)
Backport of https://github.com/Azure/sonic-buildimage/pull/7083 to the 201911 branch.

#### Why I did it

To prevent error [messages](https://dev.azure.com/mssonic/build/_build/results?buildId=2254&view=logs&j=9a13fbcd-e92d-583c-2f89-d81f90cac1fd&t=739db6ba-1b35-5485-5697-de102068d650&l=802) like the following from being logged:

```
Mar 17 02:33:48.523153 vlab-01 INFO swss#supervisord 2021-03-17 02:33:48,518 ERRO pool supervisor-proc-exit-listener event buffer overflowed, discarding event 46
```

This is basically an addendum to https://github.com/Azure/sonic-buildimage/pull/5247, which increased the event buffer size for dependent-startup. While supervisor-proc-exit-listener doesn't subscribe to as many events as dependent-startup, there is still a chance some containers (like swss, as in the example above) have enough processes running to cause an overflow of the default buffer size of 10.

This is especially important for preventing erroneous log_analyzer failures in the sonic-mgmt repo regression tests, which have started occasionally causing PR check builds to fail. Example [here](https://dev.azure.com/mssonic/build/_build/results?buildId=2254&view=logs&j=9a13fbcd-e92d-583c-2f89-d81f90cac1fd&t=739db6ba-1b35-5485-5697-de102068d650&l=802).

I set all supervisor-proc-exit-listener event buffer sizes to 1024, and also updated all dependent-startup event buffer sizes to 1024, as well, to keep things simple, unified, and allow headroom so that we will not need to adjust these values frequently, if at all.

update SDK/FW and SAI to new version (#7040)
- Why I did it
To pick up new features and fix from SDK/FW and SAI

SDK/FW new Feature:

All | Added support for multiple modules and cable types. For full list contact Nvidia networking support
Spectrum-3 | SN46000C | Added support for up to 5W on ports 49 to 64 .
SDK/FW bugs' fix:

All | fast reboot | fast boot failure from latest 201811 to 201911 and above
Spectrum | 10GbE/1GbE Transceiver (FTLX8574D3BCV) stopped working after firmware upgrade
Spectrum-2 | When device is rebooted with locked Optical Transceivers in split mode, the firmware may get stuck
Spectrum-2 | SN3700 | When connecting at 200GbE to Ixia K400, Ixia receives CRC errors
Spectrum-2 | SN3800 | On rare occasions packets loss may be experienced due to signal integrity issues
Spectrum-2 | When the port is a member of a LAG, after a warmboot and port toggle on the peer-side, the port remains down
Spectrum-3 | SN4700 | While using Optic cable in Split 4x1 mode in PAM4, when two first ports are toggled, the other 2 ports go down
Spectrum-3 | SN4700 | When working in 400GbE, deleting the headroom configuration (changing buffer size to zero) on the fly may cause continual packet drops
SAI

All | Counters | Update tunnel decap counter to capture VNI miss
- How I did it
Update the related version number in the make files and update the submodule pointer accordingly.

- How to verify it
Run regression test and everything works good.

22a19e87aa [build]: wait for conflicts package to be uninstalled (#5039)
when parallel build is enabled, both docker-fpm-frr and docker-syncd-brcm
is built at the same time, docker-fpm-frr requires swss which requires to
install libsaivs-dev. docker-syncd-brcm requires syncd package which requires
to install libsaibcm-dev.

since libsaivs-dev and libsaibcm-dev install the sai header in the same
location, these two packages cannot be installed at the same time. Therefore,
we need to serialize the build between these two packages. Simply uninstall
the conflict package is not enough to solve this issue. The correct solution
is to have one package wait for another package to be uninstalled.

For example, if syncd is built first, then it will install libsaibcm-dev.
Meanwhile, if the swss build job starts and tries to install libsaivs-dev,
it will first try to query if libsaibcm-dev is installed or not. if it is
installed, then it will wait until libsaibcm-dev is uninstalled. After syncd
job is finished, it will uninstall libsaibcm-dev and swss build job will be
unblocked.

To solve this issue, _UNINSTALLS is introduced to uninstall a package that
is no longer needed and to allow blocked job to continue.

8bcdefbc34 [docker-orchagent]: make build depends only on sairedis package (#6467)
backport c4b5b002c3

make swss build depends only on libsairedis instead of syncd. This allows to build swss without depending
on vendor sai library.

Currently, libsairedis build also buils syncd which requires vendor SAI lib. This makes difficult to build
swss docker in buster while still keeping syncd docker in stretch, as swss requires libsairedis which also
build syncd and requires vendor to provide SAI for buster. As swss docker does not really contain syncd
binary, so it is not necessary to build syncd for swss docker.

[201911][Mellanox] Add hw-mgmt patch to support SDK OFFLINE event handling during ISSU (#6551)
In order to prevent "mlxsw_minimal" driver accessing ASIC during in
service firmware upgrade flow, SDK will raise "OFFLINE" 'udev' event
at early beginning of such flow. When this event is received,
hw-managemnet will remove "mlxsw_minimal" driver.
There is no need to implement opposite "ONLINE" event, since this flow
is ended up with "kexec".

1. A SFP object is initialized to QSFP type by default when there is no SFP present
2. User insert a SFP with an adapter to this QSFP port
3. The SFP object fail to read EEPROM because it still treats itself as QSFP.

f7d753fd70 [Mellanox] Configure SAI to log to syslog instead of stdout. (#5634)
Example of syslog message from Mellanox SAI:

There is a log INFO from supervisord which actually printed NOTICE and
date again. This confusion happens becuase if SAI is not built to log
to syslog it will log everything to stdout with format "[date] [level]
[message]" so supervisord sends it to syslog with level INFO.

b70c6f72b2 [dockers][supervisor] Increase event buffer size for dependent-startup (#5247)
When stopping the swss, pmon or bgp containers, log messages like the following can be seen:

```
Aug 23 22:50:43.789760 sonic-dut INFO swss#supervisord 2020-08-23 22:50:10,061 ERRO pool dependent-startup event buffer overflowed, discarding event 34
Aug 23 22:50:43.789760 sonic-dut INFO swss#supervisord 2020-08-23 22:50:10,063 ERRO pool dependent-startup event buffer overflowed, discarding event 35
Aug 23 22:50:43.789760 sonic-dut INFO swss#supervisord 2020-08-23 22:50:10,064 ERRO pool dependent-startup event buffer overflowed, discarding event 36
Aug 23 22:50:43.789760 sonic-dut INFO swss#supervisord 2020-08-23 22:50:10,066 ERRO pool dependent-startup event buffer overflowed, discarding event 37
```

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.
