Make the accepted log grep pattern more strict in order to not pick up any log
entries from sshd causing intermittent failures.

Discussed with bluhm@ back in August this year.

Error messages for LibreSSL have changed when switching to TLS 1.3.

Currently LibreSSL reports an unknown SSL_internal error. Adjust
regex in test. So make regress passes for the release, the error
message will be improved later.

In the sendsyslog-dropped test the client has to write a log message
before syslogd is running. To fix a race in regress, delay the
syslogd startup until the message has been written. For debugging

syslogd startup until the message has been written. For debugging
add the process class to all die messages.

Check that the hostname added by syslogd -h in file and server log
is correct. Use generic redo functions. Do syntax check for all
Perl files.

Syslogd's debug and error messages have changed a bit, adapt test.

When connecting to a non existing tcp listen socket on localhost,
connect(2) does no longer fail immediately. It reports EINPROGRESS
first, an ECONNREFUSED or EPIPE error follows later. Allow this

Error messages form libtls have changed, adapt syslogd tests.
