Re: [PATCH 4/4] softmmu: move parsing of -runas, -chroot and -daemonize code

With the future intent to try to move to a fully QAPI driven configuration system, we want to have any current command parsing well isolated from logic that applies the resulting configuration. We also don't want os-posix.c to contain code that is specific to the system emulators, as this file is linked to other binaries too. To satisfy these goals, we move parsing of the -runas, -chroot and -daemonize code out of the os-posix.c helper code, and pass the parsed data into APIs in os-posix.c. As a side benefit the 'os_daemonize()' function now lives upto to its name and will always daemonize, instead of using global state to decide to be a no-op sometimes. Signed-off-by: Daniel P.
