t_server_null: multiple improvements and fixes

* Waits until servers have launched. Then launch all clients, wait for
them to exit and then check test results by parsing the client log files. Each
client kills itself after some delay using an "--up" script.
-Note that "make check" moves on once *t_server_null_client.sh* has exited. At
-that point *t_server_null_server.sh* is still running, because it exists only
-after waiting a few seconds for more client connections to potentially appear.
-This is a feature and not a bug, but means that launching "make check" runs too
-quickly might cause test failures or unexpected behavior such as leftover
-OpenVPN server processes.
