[PATCH 1/4] systemd: enable syslog.socket by default

[Chen Qi]

The syslog daemon behaviour in our systemd system should be like the following
1. If ForwardToSyslog is disabled, no daemon should be started.
2. If ForwardToSyslog is enabled, daemon should be started via socket
   activation. This is very important for OE based system. Because unlike
   other distros, OE allows serveral syslog packages installed into one
   image, using ALTERNATIVE mechanism to manage them. If the syslog
   service is started regardless of socket activation, things crash.
   For example, if there's 'WantedBy=multi-user.target' in the '[Install]'
   section of busybox-syslog.service file, then this service would be started
   anyway, even if syslog.service doesn't point to it. In this case,
   /sbin/syslogd in busybox-syslog.service might be from other syslog packages
   like sysklogd or rsyslog.

This patch is series of patches to implement the above behaviour. The
syslog.socket needs to be enabled by default so that other syslog service
could correctly be activated via socket activation at runtime.

[PATCH 2/4] busybox: fix for syslog service in systemd

[Chen Qi]

This patch includes the following changes:
1. Explicitly set StandardOutput of the log daemon to null.
   This would avoid creating a feedback loop of the syslog service.
   See link below for more information.
   http://www.freedesktop.org/wiki/Software/systemd/syslog/

2. Use ALTERNATIVE machanism to manage the syslog service file.
   This is because that other package may also provide a syslog
   implementation.

3. Make the syslog daemon socket activated only. Otherwise, things
   would crash if we install busybox-syslog and other syslog packages
   together in one image.

[PATCH 3/4] sysklogd: add systemd support

[Chen Qi]

This patch includes the following changes:
1. Add socket activation support for sysklogd.
2. Add systemd service file.
3. Use ALTERNATIVE mechanism in OE to manage the syslog service.
4. Set ALTERNATIVE_PRIORITY to "100" regardless of whether 'systemd'
   is in DISTRO_FEATURE or not because sysklogd now has systemd support.

[PATCH 4/4] sysklog: comment out configuration regarding xconsole

[Chen Qi]

I commented out these configurations for the following reasons:
We don't have xconsole utility in OE. These configurations are useless
for us.

Besides, the /dev/xconsole device is created in the init script which means
if these configuration are enabled, we need to add a script in sysklogd which
creates /dev/xconsole and is invoked in ExecStartPre in the sysklogd's service
file.

I think it's better that we just comment these lines out.
