[ovs-dev] [PATCH v2 0/2] Add performance measurement library

[Mark Michelson]

This set of commits adds a new library for OVS that allows for measuring
the performance of operations in OVS and compiling statistics from these
measurements.

For developers, this can provide a measurement of something that is
either finer or coarser-grained than what is easily measured with a
profiler.

v1 -> v2:
In version 1, there was a patch included that would save statistics to
the OVS database. Based on feedback from that, I decided to forgo
database support for the time being. If database support were to be
added, using a time series database rather than the OVS database would
be the way to go.

Removal of the database patch had a snowball effect that has reduced the
overall size of the patchset.
