Main function return value is int type, so add return
value in the end

This variable is never referenced in the code, just remove them.

Add a test to verify sampling packets via psample works.
In order to do that, create a subcommand in ovs-dpctl.py to listen to
on the psample multicast group and print samples.

The trunc action was supported decode-able but not parse-able. Add
support for parsing the action string.

The userspace action lacks parsing support plus it contains a bug in the
name of one of its attributes.
This patch makes userspace action work.

** Background **
Currently, OVS supports several packet sampling mechanisms (sFlow,
per-bridge IPFIX, per-flow IPFIX). These end up being translated into a
userspace action that needs to be handled by ovs-vswitchd's handler
threads only to be forwarded to some third party application that

The open() function returns -1 on error. openat() and open() initialize
'from' and 'to', and only 'from' validated with 'if' statement. If the
initialization of variable 'to' fails, we should better check the value
of 'to' and close 'from' to avoid possible file leak. Improve the checking
of 'from'
