High: nfsserver: Improve support for v3 file lock recovery

The nfs-lock daemon may look in /var/lib/nfs/sm or
/var/lib/nfs/statd/sm depending on the version. This patch detects
if the statd folder should be used for lock failover.
High: nfsserver: Maintain SELinux permissions on failover for nfs v3 lock state
High: nfsserver: Enable file locking daemon when systemd is being used
High: nfsserver: Cleanup shared nfs dir mount
Med: Look for "sm-notify" in $PATH.

Useful for eg. RHEL6-compatible distributions; yes, it can be specified,
but if it works "by default" it's still better.

Medium: mysql: Attempt to autodetect default mysqld pid file location.
Medium: Raid1: do not test for device existence in the stop operation (bnc#821861)

Sometimes udevd may not react quickly enough and remove the
devices, hence the stop operation may unnecessarily fail. Whether
a device file exists or not is anyway irrelevant when stopping.
Low: doc: fix spelling and improve style in meta-data (thanks to the SUSE documentation team)
Medium: ethmonitor: correctly detect when the network is unplugged.

The ethmonitor does not return the correct status
1). when the wire is unplugged from network interface,
    for example, the output for eth0 is:
    # ip -o link show up dev eth0
    # eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state
DOWN qlen 1000
2). when lower layer is down for a VLAN, for example, the output:
    # ip -o link show up dev vlan2
    # vlan2@bond2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc
noqueue state LOWERLAYERDOWN

Solution:
    both of the above status can be detected by 'grep NO-CARRIER'
Medium: tools: send_arp.libnet: reuse ARP packets (debian#701914)

This is just a reshuffle of code to have the libnet packets
reused instead of creating new ones each time a packet is to be
sent. There are no functional changes, the program should be a
bit faster and require less resources (memory in particular).
High: postgres-8: Shutdown postgres with SIGINT before forcing SIGQUIT

SIGINT should be attempted shutdown the postgres server before
issuing a SIGQUIT to force the shutdown.  The shutdown signals
are documented here.
