A lot of tests need to initialize the OVS_RUNDIR, OVS_LOGDIR, etc.
variables to point to the directory in which the tests run.  Until now,
each of them has had to do this individually, which is redundant.  This
commit starts to do this automatically.

Improve link speed by linking 29 test programs into ovstest.

On my machine, running the following command against a fully
built tree:

  $ touch lib/random.c; time make

Improve the overall build time from 7 seconds to 3.5 seconds.

Until now, "unix:" and "punix:" paths that are not absolute have
been considered relative to the current working directory.  It
is more useful to consider them relative to the rundir, so this
commit makes that change to the C and Python implementations of
the stream code.

This commit also relaxes the whitelist check in the bridge code
so that any name that does not contain a "/" is considered OK.

The tests have been failing for a few days now, because the PKI expired a
few days into 2011.  This commit instead generates the PKI at "make check"
time, which has the additional benefit of getting some test exposure for
the ovs-pki program.
