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.
Add a master switch so that the sync/async mode can be configured.
Example usage of the switch:
1. Configure mode while building an image
`make ENABLE_SYNCHRONOUS_MODE=y <target>`
2. Configure when the device is running
Change CONFIG_DB with `sonic-cfggen -a '{"DEVICE_METADATA":{"localhost": {"synchronous_mode": "enable"}}}' --write-to-db`
Restart swss with `systemctl restart swss`

Swap order of orchagent and portsyncd in start.sh and fix priorities
Many docker virtual switch tests are failing at the moment because orchagent never finishes initializing. After doing some searching I figured out that Ethernet24 is never published to State DB, which is reminiscent of #4821

Applications running in the host OS can read the platform identifier from /host/machine.conf. When loading configuration, sonic-config-engine *needs* to read the platform identifier from machine.conf, as it it responsible for populating the value in Config DB.
When an application is running inside a Docker container, the machine.conf file is not accessible, as the /host directory is not mounted. So we need to retrieve the platform identifier from Config DB if get_platform() is called from inside a Docker
container. However, we can't simply check that we're running in a Docker container because the host OS of the SONiC virtual switch is running inside a Docker container. So I refactored `get_platform()` to:
1. Read from the `PLATFORM` environment variable if it exists (which is defined in a virtual switch Docker container)
2. Read from machine.conf if possible (works in the host OS of a standard SONiC image, critical for sonic-config-engine at boot)
3. Read the value from Config DB (needed for Docker containers running in SONiC, as machine.conf is not accessible to them)
- Also fix typo in daemon_base.py
- Also changes to align `get_hwsku()` with `get_platform()`
- Created the VS setup to test DPB functionality
- Created "platform.json" for VS docker
- Added test case for Breakout CLI

As part of consolidating all common Python-based functionality into the new sonic-py-common package, this pull request:
1. Redirects all Python applications/scripts in sonic-buildimage repo which previously imported sonic_device_util or sonic_daemon_base to instead import sonic-py-common, which was added in https://github.com/Azure/sonic-buildimage/pull/5003
2. Replaces all calls to `sonic_device_util.get_platform_info()` to instead call `sonic_py_common.get_platform()` and removes any calls to `sonic_device_util.get_machine_info()` which are no longer necessary (i.e., those which were only used to pass the results to `sonic_device_util.get_platform_info()`.
3. Removes unused imports to the now-deprecated sonic-daemon-base package and sonic_device_util.py module
This is the next step toward resolving https://github.com/Azure/sonic-buildimage/issues/4999
Also reverted my previous change in which device_info.get_platform() would first try obtaining the platform ID string from Config DB and fall back to gathering it from machine.conf upon failure because this function is called by sonic-cfggen before the data is in the DB, in which case, the db_connect() call will hang indefinitely, which was not the behavior I expected. As of now, the function will always reference machine.conf.
virtual-chassis test uses multiple vs instances to simulate a
modular switch and a redis-chassis service is required to run on
the vs instance that represents a supervisor card.
This change allows vs docker start redis-chassis service according
to external config file.
**- Why I did it**
To support virtual-chassis setup, so that we can test distributed forwarding feature in virtual sonic environment, see `Distributed forwarding in a VOQ architecture HLD` pull request at https://github.com/Azure/SONiC/pull/622
**- How I did it**
The sonic-vs start.sh is enhanced to start new redis_chassis service if external chassis config file found. The config file doesn't exist in current vs environment, start.sh will behave like before.
**- How to verify it**
The swss/test still pass. The chassis_db service is verified in virtual-chassis topology and tests which are in following PRs.

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.

**- Why I did it**
Initially, the critical_processes file contains either the name of critical process or the name of group.
For example, the critical_processes file in the dhcp_relay container contains a single group name
`isc-dhcp-relay`. When testing the autorestart feature of each container, we need get all the critical
processes and test whether a container can be restarted correctly if one of its critical processes is
killed. However, it will be difficult to differentiate whether the names in the critical_processes file are
the critical processes or group names. At the same time, changing the syntax in this file will separate the individual process from the groups and also makes it clear to the user.
Right now the critical_processes file contains two different kind of entries. One is "program:xxx" which indicates a critical process. Another is "group:xxx" which indicates a group of critical processes
managed by supervisord using the name "xxx". At the same time, I also updated the logic to
parse the file critical_processes in supervisor-proc-event-listener script.
**- How to verify it**
We can first enable the autorestart feature of a specified container for example `dhcp_relay` by running the comman `sudo config container feature autorestart dhcp_relay enabled` on DUT. Then we can select a critical process from the command `docker top dhcp_relay` and use the command `sudo kill -SIGKILL <pid>` to kill that critical process. Final step is to check whether the container is restarted correctly or not.

DPKG caching framework provides the infrastructure to cache the sonic module/target .deb files into a local cache by tracking the target dependency files.SONIC build infrastructure is designed as a plugin framework where any new source code can be easily integrated into sonic as a module and that generates output as a .deb file. The source code compilation of a module is completely independent of other modules compilation. Inter module dependency is resolved through build artifacts like header files, libraries, and binaries in the form of Debian packages. For example module A depends on module B. While module A is being built, it uses B's .deb file to install it in the build docker.
The DPKG caching framework provides an infrastructure that caches a module's deb package and restores it back to the build directory if its dependency files are not modified. When a module is compiled for the first time, the generated deb package is stored at the DPKG cache location. On the subsequent build, first, it checks the module dependency file modification. If none of the dependent files is changed, it copies the deb package from the cache location, otherwise, it goes for local compilation and generates the deb package. The modified files should be checked-in to get the newer cache deb package.
This provides a huge improvement in build time and also supports the true incremental build by tracking the dependency files.
- How I did it
It takes two global arguments to enable the DPKG caching, the first one indicates the caching method and the second one describes the location of the cache.
SONIC_DPKG_CACHE_METHOD=cache
SONIC_DPKG_CACHE_SOURCE=
where SONIC_DPKG_CACHE_METHOD - Default method is 'cache' for deb package caching
none: no caching
cache: cache from local directory
Dependency file tracking:
Dependency files are tracked for each target in two levels.
1. Common make infrastructure files - rules/config, rules/functions, slave.mk etc.
2. Per module files - files which are specific to modules, Makefile, debian/rules, patch files, etc.
For example: dependency files for Linux Kernel - src/sonic-linux-kernel,
SPATH := $($(LINUX_HEADERS_COMMON)_SRC_PATH)
DEP_FILES := $(SONIC_COMMON_FILES_LIST) rules/linux-kernel.mk rules/linux-kernel.dep
DEP_FILES += $(SONIC_COMMON_BASE_FILES_LIST)
SMDEP_FILES := $(addprefix $(SPATH)/,$(shell cd $(SPATH) && git ls-files))
DEP_FLAGS := $(SONIC_COMMON_FLAGS_LIST) \
$(KERNEL_PROCURE_METHOD) $(KERNEL_CACHE_PATH)
$(LINUX_HEADERS_COMMON)_CACHE_MODE := GIT_CONTENT_SHA
$(LINUX_HEADERS_COMMON)_DEP_FLAGS := $(DEP_FLAGS)
$(LINUX_HEADERS_COMMON)_DEP_FILES := $(DEP_FILES)
$(LINUX_HEADERS_COMMON)_SMDEP_FILES := $(SMDEP_FILES)
$(LINUX_HEADERS_COMMON)_SMDEP_PATHS := $(SPATH)
Cache file tracking:
The Cache file is a compressed TAR ball of a module's target DEB file and its derived-target DEB files.
The cache filename is formed with the following format
FORMAT:
<module deb filename>.<24 byte of DEP SHA hash >-<24 byte of MOD SHA hash>.tgz
Eg:
linux-headers-4.9.0-9-2-common_4.9.168-1+deb9u3_all.deb-23658712fd21bb776fa16f47-c0b63ef593d4a32643bca228.tgz
< 24-byte DEP SHA value > - the SHA value is derived from all the dependent packages.
< 24-byte MOD SHA value > - the SHA value is derived from either of the following.
GIT_COMMIT_SHA - SHA value of the last git commit ID if it is a submodule
GIT_CONTENT_SHA - SHA value is generated from the content of the target dependency files.
Target Specific rules:
Caching can be enabled/disabled on a global level and also on the per-target level.
$(addprefix $(DEBS_PATH)/, $(SONIC_DPKG_DEBS)) : $(DEBS_PATH)/% : .platform $$(addsuffix -install,$$(addprefix $(DEBS_PATH)/,$$($$*_DEPENDS))) \
$(call dpkg_depend,$(DEBS_PATH)/%.dep )
$(HEADER)
# Load the target deb from DPKG cache
$(call LOAD_CACHE,$*,$@)
# Skip building the target if it is already loaded from cache
if [ -z '$($*_CACHE_LOADED)' ] ; then
.....
# Rules for Generating the target DEB file.
.....
# Save the target deb into DPKG cache
$(call SAVE_CACHE,$*,$@)
fi
$(FOOTER)
The make rule-'$(call dpkg_depend,$(DEBS_PATH)/%.dep )' checks for target dependency file modification. If it is newer than the target, it will go for re-generation of that target.
Two main macros 'LOAD_CACHE' and 'SAVE_CACHE' are used for loading and storing the cache contents.
The 'LOAD_CACHE' macro is used to load the cache file from cache storage and extracts them into the target folder. It is done only if target dependency files are not modified by checking the GIT file status, otherwise, cache loading is skipped and full compilation is performed.
It also updates the target-specific variable to indicate the cache is loaded or not.
The 'SAVE_CACHE' macro generates the compressed tarball of the cache file and saves them into cache storage. Saving into the cache storage is protected with a lock.
- How to verify it
The caching functionality is verified by enabling it in Linux kernel submodule.
It uses the cache directory as 'target/cache' where Linux cache file gets stored on the first-time build and it is picked from the cache location during the subsequent clean build.
- Description for the changelog
The DPKG caching framework provides the infrastructure to save the module-specific deb file to be cached by tracking the module's dependency files.
If the module's dependency files are not changed, it restores the module deb files from the cache storage.
