Makefile: add gcc flags to prevent some optimization 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.

Misc: lifemngr-daemon-on-UOS for windows For cross-VM S5 notify via vUART, life_mngr service is running on UOS. It is listening on COM2 to get SOS's commands. The protocol is: SOS send "shutdown", UOS feedback "acked". When SOS triggle shutdown, SOS can 1) check VM's status until UOS stopped, 2) retry shutdown UOS normally with timeout. So, no matter life_mngr server is running, SOS's shutdown procedure will properly finish. Tracked-On: #3564 Signed-off-by: Yuan Liu <yuan1.liu@intel.com>
