Create a log file for each test run. Stdout and stderr of the test script,
as well as any subprocesses run as part of the test, are redirected to
the log file. This makes it a lot easier to debug test failures. Also print
the test output (ok 12 - ... messages) to the log file, and the command
line of any external programs executed with the system_or_bail and run_log
functions. This makes it a lot easier to debug failing tests.
Modify some of the pg_ctl and other command invocations to not use 'silent'
or 'quiet' options, and don't redirect output to /dev/null, so that you get
all the information in the log instead.
In the passing, construct some command lines in a way that works if $tempdir
contains quote-characters. I haven't systematically gone through all of
them or tested that, so I don't know if this is enough to make that work.
pg_rewind tests had a custom mechanism for creating a similar log file. Use
the new generic facility instead.

This is a backpatch of Heikki's commit 1ea06203b8.
All the other certificates were created to be valid for 10000 days, because
we don't want to have to recreate them. But I missed the root CA cert, and
the pre-created certificates included in the repository expired in January.
Fix, and re-create all the certificates.
It's not run by the global "check" or "installcheck" targets, because the
temporary installation it creates accepts TCP connections from any user
the same host, which is insecure.
