Commit 96c33a4 ("log: Redirect stderr to logfile if deamonized",
2016-02-22) wanted to move stderr of a daemonized QEMU to the file
specified with -D.
However, if -D was not passed, the patch had the side effect of not
redirecting stderr to /dev/null. This happened because qemu_logfile
was set to stderr rather than the expected value of NULL. The fix
is simply in the "if" condition of do_qemu_set_log; the "if" for
closing the file is also changed to match.

In case of daemonize, use the logfile passed with the -D option in
order to redirect stderr to it instead of /dev/null.
Also remove some unused code in log.h.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This is a bit easier to use than "-trace" if you are also enabling
other kinds of logging. It is also more discoverable for experienced
QEMU users, and accessible from user-mode emulators.
