Add the below flags, they are needed in -O2:
-fno-delete-null-pointer-checks:
* tells the compiler NOT to assume that null pointer deference does
not exist.
* Without this flag, below case cannot be detected:
a pointer might point to nullsometime during run-time and if there
is no validation for that pointer, it will cause the program to crash.
Since we don’t receive an error message saying that a pointer is
pointing to null, we will have a hard time trying to find the problem.
-fwrapv:
* tells the compiler that signed overflow always wraps.
* Without this flag, x + 10 > x will always be true for signed x.
With the flag, x + 10 > x is not always be true, as the overflow is
defined for x, and it could wrap.

The return value of 'strtol()' is not checked properly
in _get_vmname_pid() @acrn_vm_ops.c and parse_opt()@acnrd.c,
the return type of 'strtol' is 'long int', but it is assigned
to a variable with type of 'int' and compared to "LONG_MAX"
and "LONG_MIN", which is always false.
This patch is to fix above error case.

Run 'acrnctl stop VM_NAME --force‘ to force stop VM
When run 'acrnctl stop VM_NAME', acrn-dm let guest OS to shutdown
itself. If something wrong with guest OS, it can't shutdown, we can
run 'acrnctl stop VM_NAME --force', thus acrn-dm directly set suspend
mode to VM_SUSPEND_POWEROFF and quit main loop.

Add 'force' parameter to acrn_stop(), which will be write to request
message, the value of data.acrnd_stop.force. So we can tell DM to
force stop VM, instead of telling UOS to shutdown itself.
