1. Reorder http.conf to actually read worker config
2. Change functions so that the TPS would restart.  Before restarts
   would fail because the tus link already exists
3. Modify system verification test to return correctly when tests
   are successful

Added required selinux versions to spec file.  Also added
additional rule needed for F17

Ticket 356

The deployment and init scripts have been fixed to create and check
the link to symkey.jar if a TKS instance is added, and remove the
link if the instance is removed.

Ticket #331

* TRAC Ticket #301 - Need to modify init scripts to verify needed
  symlinks in an instance (support non-default instance names)

CMS engine is a singleton and it's used by PKI realm to authenticate
users accessing the subsystem. Since a Tomcat instance may contain
multiple subsystems, each having separate realm, the PKI JAR links
need to be moved into WEB-INF/lib so that they will run inside
separate class loaders.

Tomcat also requires that the authenticator and realm classes be
available in common/lib. To address this a new package pki-tomcat.jar
has been added. The package contains the authenticator and a proxy
realm. When the subsystems start running, they will register their
own realms into the proxy realms such that the authentications will
be forwarded to the appropriate subsystems.

  symlinks in an instance
* TRAC Ticket #303 - Dogtag 10: CS.cfg parameters for Dogtag 9 instance
  running under Dogtag 10 packages . . .

Added systemd scripts for RA and TPS.  Modified init scripts
and configuration files to use correct directives for httpd 2.4.
TPS and RA subsystems are now installable using pkicreate
