    qemu-log: default to stderr for logging output · 989b697d
    Peter Maydell authored
    Switch the default for qemu_log logging output from "/tmp/qemu.log"
    to stderr. This is an incompatible change in some sense, but logging
    is mostly used for debugging purposes so it shouldn't affect production
    use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log"
    to the command line.
    
    This change requires us to:
     * update all the documentation/help text (we take the opportunity
       to smooth out minor inconsistencies between the phrasing in
       linux-user/bsd-user/system help messages)
     * make linux-user and bsd-user defer to qemu-log for the default
       logging destination rather than overriding it themselves
     * ensure that all logfile closing is done via qemu_log_close()
       and that that function doesn't close stderr
    as well as the obvious change to the behaviour of do_qemu_set_log()
    when no logfile name has been specified.
