acrn-manager message structure has a flexible member
payload[0], that risks to out-of-boundary memory access,
and usage of uninitialized variable.
And the req/ack message pairs has various types, which
extend mngr_msg. mngr_send_msg() requires programmer cast
the type of input messages to struct mngr_msg, that is
inconvenient.
We replace payload[0] with an union, which contains all
payload data. So that type cast for mngr_send_msg() is no
longer needed. And we can avoid potential out-of-boundary
memory accessing and using of uninitialized variable

The install -D is misleading people since it only creates the leading
directories.
The problem was hidden due to we always call make install and the
destination folder was already created in previous install script.

Due to cbc_lifecycle service already has its own retry mechanism,so change the
Restart type to "no".
This change is also indirectly avoid cbc_lifecycle always restart for the
non-IOC boards. Actually, there has one defect for current IOC CBC architecture
due to lack IOC hardware detection mechanism. The related guys are already aware
it and WIP.

This patch resolved systemd be blocking for 20 seconds due to waiting the
"READY=1" from cbc_attach. And cbc_attach will retry 60 sec at the worst case
which can be reproduced on non-IOC boards.
This is one temporary solution. The final solution need modify SBL to export IOC
ACPI device through ACPI table, and also Linux IOC CBC driver need trigger
uevent which should be the trigger of launching cbc_attach service.
This patch changes the service type to simple instead of notify due to systemd is
needn't wait cbc related services. And change Restart to no due to cbc_attach
already has retry mechanism.
These changes are also reasonable for the board integrated IOC component.
So they should be keep even the long term final solution implemented.

This is one workaround patch to resolve read/write failed for /dev/cbc-lifecycle
and /dev/cbc-signals cdev nodes. It cause cbc_lifecycle service can't send
heartbeat to IOC firmware, also can't receive any signal data from IOC firmware.
This patch need to be revert once the IOC firmware or CBC driver fixed the root
cause.
The [-f] option means enable hardware flow control by set CRTSCTS attribute for
c_cflag of termios, without [-f] option will unset the attribute.

The 'cbc_lifecycle' component fails to build when using a custom
output directory (e.g.: 'make O=build-test'). This patch fixes
this by replacing a hard-coded path with the variable that points
at the right location where to find its target dependencies.

cbc_attach is one SOS service that enable IOC CBC line discipline feature.
It started by systemd by default, and exit if failed to set the line
discipline that means the platform does not support IOC.

The cbc_lifecycle service will listen on /dev/cbc-lifecycle tty port to
receive "wakeup reason" information from ioc controller as well as send
heartbeat to ioc to set different power cycle method.
The RTC funtionality is not implemented by current ioc firmware yet,
hence the service leaves it as an empty handler now.
