SONiC is a heavy writer to /var/log partition, we noticed that this
behavior causes certain flash drive to become read-only over time.
To avoid this issue, we mount /var/log parition on these devices as
tmpfs.
- Mount /var/log as tmpfs
- /var/log default size is 128M
- Adjust size according to existing var-log.ext4 file size.
- Adjust size to between 5% to 10% of total memory size.

* Updated Makefile infrastructure to build debug images.
As a sample, platform/broadcom/docker-orchagent-brcm.mk is updated to add a docker-orchagent-brcm-dbg.gz target.
Now "BLDENV=stretch make target/docker-orchagent-brcm-dbg.gz" will build the debug image.
This debug image can be used in any linux box to inspect core file. If your module's external dependency can be suitably mocked, you my even manually run it inside.
"docker run -it --entrypoint=/bin/bash e47a8fb8ed38"
You may map the core file path to this docker run.
* Dropped the regular binary using DBG_PACKAGES and a small name change to help readability.
* Tweaked the changes to retain the existing behavior w.r.t INSTALL_DEBUG_TOOLS=y.
When this change ('building debug docker image transparently') is extended to all dockers, this flag would become redundant. Yet, there can be some test based use cases that rely on this flag.
Until after all the dockers gets their debug images by default and we switch all use cases of this flag to use the newly built debug images, we need to maintain the existing behavior.
After warm reboot is done, we need to disable warm reboot flag and
tear down anything setup for warm reboot and persisted across.

There are some platforms with less powerful CPU/hard-drive could take
longer to get ready for BGP. For these platforms, 240 seconds would be
a safer threshold.

When adding a lag member dynamically after system boots up, teamd
port priv change handler could re-entrant itself and causing adding
operation to fail.
While handling PORT_CHANGE event, teamd_per_port.c port priv change
handler was called, it will then call runner_lacp to add port to lag,
the later causes IFINFO_CHANGE to be notified and calls the priv change
handler again, this re-entrance would cause runner_lacp port_added to
be called again and messes up with the previous adding sequence. Then
fails the lag member adding operation.
Prevent per port priv change handler re-entrance solves the problem.

* [vm build] force Linux to drop cache before calling kvm
KVM need to allocate 2G memory for this build. The system memory might
be occupied by cache at the moment and doesn't have 2G chunk to give
out. Forcing Kernel to drop cache to boost the chance of getting 2G
memory.

Race condition has been noticed after warm reboot: sometimes when
port_changed notification was received, the link message didn't
have the device name. Without device name, creating team port
would fail.
Registering to the interface information change notification, so
later when device name becomes available, retry creating team port.
