This allows people to chroot sslh into a path to further harden it.
We have to rework the user logic a bit because we need to look up
the user details *before* we chroot (as we need to read /etc/passwd
files), but do the actual priv dropping *after* we chroot (so we
have permission to make the actual chroot call).
Similarly, we need to open the syslog before we drop privs because
/dev/log won't be available inside the chroot.
This patch allows to set option --transparent in an SSLH configuration
file. Without it, transparent mode is only possible by passing the
option on the command line.
Corrected OpenVPN probe to support pre-shared secret
mode (OpenVPN port-sharing code is... wrong). Thanks
to Kai Ellinger for help in investigating and
testing.
Added an actual TLS/SSL probe.
Added configurable --on-timeout protocol
specification.
Added a --anyprot protocol probe (equivalent to what
--ssl was).
Makefile respects the user's compiler and CFLAG
choices (falling back to the current values if
undefined), as well as LDFLAGS.

Added "After" and "KillMode" to systemd.sslh.service
(Thomas Weischuh).
Added LSB tags to etc.init.d.sslh
(Thomas Varis).
