The CMake scripts have been modified to remove redundant
invocations of find_file() to find Tomcat libraries.

The list of source and class files in some CMake files have been
generalized to allow renaming Java packages without changing the
CMake files again.

Look for the right JAX-RS API JAR (it has moved in Fedora 25).

Also remove a lot of redundant 'find_file' operations for this JAR.

All methods in ProxyRealms for Tomcat 7 and 8 have been modified
to check whether the subsystem is available, then generate a proper
error message instead of null pointer exception.

Two Tomcat version-specific implementations of
SSLAuthenticatorWithFallback exist, with much duplicate code.
Extract an abstract base class 'AbstractPKIAuthenticator' and
implement just the unique bits in the concrete classes.

This is the first of several commits.  This adds a LifecycleListener
to call init() on the nuxwdog client before any connectors or webapps
start up, and call sendEndInit() once initialization completes.

Code is also added to prompt for and test required passwords on startup.
All that is required to use nuxwdog is to start the server using nuxwdog.
An environment variable will be set that will trigger creation of the
NuxwdogPasswordStore.  We expect tags for the required passwords to be in
cms.passwordList

The Dogtag code has been modified to support both Tomcat 7 and 8.
All files depending on a specific Tomcat version are now stored
in separate folders. The build scripts have been modified to use
the proper folder for the target platform. The tomcatjss
dependency has been updated as well.

The upgrade script will be added in a separate patch.
