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.

this patch aim at
1. Use new IPC lib to connect acrn-dm.
2. Export list_vm, start_vm and stop_vm and acrnd will use them later.
3. Rename vmm releated struct and function
