dbus-sysdeps-win.c makes use of a constant called
PROCESS_QUERY_LIMITED_INFORMATION, which was added after Windows
XP. There is code present to make sure the constant is not used
when running on an XP system, but the constant is still required
at build time. Unfortunately, the Windows headers provided by
MinGW are old enough that they do not contain this constant, so
building with MinGW fails.
This patch adds a definition for the constant if one is not already
present.

Previous to the introduction of selinux_set_mapping(), DBus pulled
constants generated from the system's policy at build time. But this
means it's impossible to replace the system policy without rebuilding
userspace components.
This patch maps from arbitrary class/perm indices used by D-Bus and
the policy values and handles all the translation at runtime on
avc_has_perm() calls.

In code that looks like n[i] = v(&i), where v increments i, C leaves it
undefined whether the old or new value of i is used to locate n[i].
As it happens, gcc used the pre-increment value of i, but MSVC
used the post-increment value.
Fix this by inserting a sequence point to disambiguate the intended order.

In systemd environment, dbus-daemon will run as no-fork mode since this
is the recommended practice of systemd.
In that scenario, child activated by dbus-daemon will inherit
dbus-daemon standard streams, includes stdin/stdout/stderr. stdin will
be redirected to /dev/null by systemd and stdout/stderr will be catched
by systemd log subsystem. Since the child inherit stdout/stderr from
dbus-daemon, so from systemd journal log, the child log output will be
identified with dbus-daemon identifier. So it's a little confusing.
This patch redirects the child stdout/stderr to systemd journal stream,
and with its owned service name as identifier. However, thing not fixed
perfectly due to the socket ucred of the child is owned by dbus-daemon,
so the pid isn't the real pid of the chile.

DBusBabysitter->executable is defined as executable name to use in error
messages. However, if servicehelper used, then the executable name is
servicehelper. It's not much help because we couldn't figure out which
service we're trying to activated if error happens.
In the following patch, we'll use service name to be activated as the
child log identifier and add a parameter to
_dbus_spawn_async_with_babysitter() to pass the log identifier. Since
this is not the case in test, so executable changed to log_name.
