In handle_resume(), wakeup_reason is updated before call
ops->ops->resume(). Because ops->ops->resume() needs to know the
latest wakeup reason.

Then, acrnctl could send command to monitor module of DM and call
functions defined in pm ops. One example is: acrnctl resume UOS
after UOS enter S3.
Also add general pm.c and move pm related function to this file.

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

Adapt dm-monitor and acrnctl to use the helper functions and new message
definitions in acrn_mngr.h.
These jobs must be done in one commit to avoid build problems:
1. message transmission and callback registration code are moved
to libacrn-mngr.a, so old functions in dm-monitor could be removed to
make code clean;
2. remove unnecessary monior_msg.h;
3. minor changes to acrnctl accordingly.

A monitor component will be added to acrn-dm, which crteats socket,
bind and listening at /run/acrn/vmname. Acrnctl & acrnd could conn
-ect to the socket for communication, using defined message, in
include/monitor_msg.h
For each defined message, a message handler callback could be
registered via monitor_add_msg_handler(). On received of a defined
message, a certain call back will be called. Each callback can only
see the message sender's socket-fd.
When acrn-dm want report something, not triggered by incoming message
it can send broadcast message, use monitor_broadcast().
