[PATCH v4 1/5] softmmu: add means to pass an exit code when requesting a shutdown |
Date: |

As of now, the exit code was either EXIT_FAILURE when a panic shutdown
was requested or EXIT_SUCCESS otherwise.
However, some hardware could want to pass more complex exit codes. Thus,
introduce a new shutdown request function allowing that.
