Added spec for RHEL4

We only build the client programs
Storage to storage copy jobs don't work with TLS.

When both SDs think they are a TLS server the handshake will never be a
success. Now changed the code to use the initiate variable we have which
we already use to know who starts the challenge protocol. That way we
get one TLS server and one TLS client which should work much better.

Fixes #290: Storage to storage copy jobs don't work with TLS enabled.
Add openssl CRL reload logic.

The Bareos daemons neither try to reread configured X.509
CRLs from file system if they expire nor if the daemon receives a
SIGHUP.

Fixes #289: Add openssl CRL reload logic.
Use dbconfig for Debian based distributions

dbconfig-common is a standard mechanism for Debian based distributions,
to assists applications that require a database.

The user still has the choice to configure the database manually, if not,
dbconfig detects what database backends are installed, and the user gets
asked, what connection parameter he wants to use.

If dbconfig is configured correctly, database schema updated are done automatically
on package updates. With export DEBIAN_FRONTEND=noninteractive the user don't get ask,
and dbconfig configures the database backend as good as he can.
