timeval: Block SIGALRM when sleeping.

Commit 00a16895 (timeval: Don't require signals for time_alarm().)
Incorrectly disabled signals when when CACHE_TIME was disabled.  In
fact, the reverse was correct.  As a result of this bug, OVS would
wake once every 100ms unnecessarily.  It shouldn't have affected
correctness otherwise.

stream.py: Don't use class decorators.

Commit 8cc820 (python/ovs/stream: teach stream.py tcp socket) made a
change that used class decorators.  Unfortunately, they were not
introduced until Python 2.6.  XenServer uses Python 2.4, so the change
caused some Python-based daemons not to start.  This commit uses an
alternate syntax suggested by Reid Price.

stream.py: un-decorator Stream.register_method

c38f8724aeb994fd840fa4283a07e38c3c114d68 made stream.py not use class
decorator. So Stream.register need not to be decorator any more.
So simplify it.

timeval: Optionally enable cached timing at configure time.

Often when developing, it would be convenient to force OVS to
either enable or disable cached timing so that a feature can be
tested under both strategies.

The new ovs-parse-backtrace utility makes the output of ovs-appctl
backtrace more human readable by removing duplicate traces and
converting addresses to function names.

ofp-util: Separate output, error reporting in ofputil_port_from_string().

When I wrote this function I didn't think that port 0 was important (it's
not a valid OpenFlow port number) so I used a return value of 0 to indicate
an error.  However, my assumption turns out to be wrong, so this commit
changes the interface to use the return value only for error reporting
and store the parsed port number into a pointer passed in as a parameter.

This commit doesn't change the behavior of ofputil_port_from_string().

ofp-util: Again allow OpenFlow port 0 in commands and actions.

Commit c6100d92142b (ovs-ofctl: Accept port keywords, OF1.1 port numbers,
reject port number 0.) intentionally prohibited using port 0, which is not
a valid OpenFlow port number, in OpenFlow commands and actions.  However,
since then we have discovered that the NVP controller uses port 0 in
"resubmit" actions and hence in flow matches as well.  This seems like a
valid enough use case; after all, the port number in a resubmit action is
really just an arbitrary number that need not (and preferably does not)
refer to an actual OpenFlow port.  Therefore, this commit restores the
ability to use port 0.

(Only functions that parse OpenFlow commands and actions from strings, not
those that interpret binary OpenFlow coming in on OpenFlow connections,
were affected by this prohibition, so this only comes up in corner cases
anyhow.)
