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
add the process class to all die messages.

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

Test syslogd logging to a tty which belongs to a user. This is
done with a utmp entry for a pty fake login. All messages are read
from the pty and written into a log file.

Add tests for syslogd TLS accept and receive encrypted messages.
