* OF-1147: More debug logging.

* Removed unreachable code.

* PrivacyLists on first run
There are 2 instances of PrivacyListProvider (one in PrivacyListManager and the other in IQPrivacyHandler)

The issue was : both instances have separate privacyListCount variables, which are filled during PrivacyListProvider constructor (== server startup).
Thus, if at server startup the privacyListCount is 0, and one of the instances adds a PrivacyList, the other will never be informed and discard all changes and reads.

Fix : turn PrivacyListProvider into a singleton.

connections can be pooled and re-used.

Portable Import/Export Format for XMPP-IM Servers

A typo was fixed which caused a invalid error "The import file does not match the user schema." when importing.

This fixes a bug where the EmailService settings could not be changed
through the admin panel. Note that this is introduced in the same
version of Openfire (4.1.0) as that will include this commit.

This commit introduces a new SMS service that takes after the
existing email service. The new service utilizes SMPP to allow
for messages to be sent to a suitable service provider.

Simply repeated dwd's commit 73b59106 on Ubuntu Trusty (20160104ubuntu0.14.04.1)

Adds explicit requirement for jre-headless to be installed for the noarch RPM.

Note: the epoch is set to 1 for this requirement as well, which seems to be the convention based on https://fedorahosted.org/released/javapackages/doc/#_jvm

OF-477: For DIGEST-MD5, use domain rather than host name.
