Don't use separate asynchronous event connection for user datapath.

Commit 14439fa80c, "Maintain separate async and sync connections to nl:0
in secchan," modified secchan to use two separate connections to the
datapath, one for asynchronous events, one for requests and replies.  This
technique doesn't work for the user datapath, which always sends
asynchronous events on all its connections.  Fortunately, it isn't
necessary for the user datapath, either, because the user datapath is
smart enough not to drop message replies.

Add support for exporting flow information in NetFlow v5 format.

This is implemented by having the datapath send a new meta-Flow End message
that contains all the information needed by NetFlow v5 and the OpenFlow
Flow Expiration messages.  secchan grabs these Flow End messages and
generates any requested Flow End and NetFlow messages.  The Flow End
message is implemented as a Nicira vendor extension, but it is only used
internally between the datapath and secchan, so the switch is still fully
compatible with OpenFlow v0.8.9.

SIGTERM.  It actually returns an English explanation, so that the existing
code would log a message like "terminated by signal Terminated".  This
commit changes the message to the more sensible "terminated by signal 15
(Terminated)".

Also, the recently approved POSIX 2008 standardized strsignal() and in
particular says that it may return NULL for unknown signal numbers, so
this commit fixes the behavior on NULL return.
