Ryan Wilson 8396f8070b timeval: Use monotonic time in OVS Python timeval library. ...

Python's time.time() function uses the system wall clock. However,
if NTP resets the wall clock to be a time in the past, then this
causes any applications that poll block based on time, such as
ovs-xapi-sync, to poll block indefinitely since the time is
unexpectedly negative.

This patch fixes the issue by using time.monotonic() if Python's
version >= 3.3. Otherwise, the timeval module calls out to the
librt C shared library and uses the clock_gettime function with
CLOCK_MONOTONIC.

Note this is only enabled on Linux-based platforms. This has been
tested on Ubuntu 12.04 and Redhat 6.4.
