There is a bug to run 'acrnctl add /[path]/script.sh', when the
launch script has an absolute path. Acrnctl will generate wrong path
for temp files and fail to add VM.
And message '/opt/acrn/conf: No such file or directory' always comes
out, until user once successfully run 'acrnctl add' cmd. That is reported
by _scan_added_vm(), because 'opt/acrn' is missing, only 'acrnctl add'
can create it, we should also check it in _scan_added_vm().

When UOS is sleeping, 'acrnctl list' command show it is 'paused', not
'suspended'. That is not correct. Because pausing an UOS means to block
its VCPUs immediately, otherwise suspending an UOS means to put it to
sleep.

When guest enter S5, its monitor socket will be closed. If we try to use it to
query the vm state, an error msg will be print out. Acctually, we should not take
it as an error.
So, this patch refine the log msg to show more details when guest trying to enter
S3/S5.

The issue is "acrnctl list" command always returns error with "no vmname
provided" information.
The rootcause is that vmname is an invalid parameter, which does not contain
any vm information.

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

There are some problems to use VM operations in a deamon process,
such as Acrnd. the list_vm() does not return VM informations, it
just print VM information to stdio, so we have get_vm_list()
to get VM list head vmngr_head; get_vm_list() always creates a
new fresh vm list every time, and must use put_vm_list() to delete
old list. So Acrnd need to create and destroy vm list frequently.
In fact we just need the vmngr_head to be an extern variable. And
to make it refreshable.We can insert new VMs, remove dead ones,
and update their state.
