net/ntpa: Use .conf suffix for /usr/local/etc/newsyslog.conf.d/

- Rename the files installed to /usr/local/etc/newsyslog.conf.d/ to end
  with a '.conf' suffix.
- Add pkg-install script to automatically move any copies of the old
  newsyslog file to the new location if it was modified from the default
  or delete the old file if it is has not been modified.
- Add a note to UPDATING and pkg-message to warn users of this, in case
  they are using provisioning/configuration management tools which need
  to be modified. Note the UPDATING entry was committed in r485721.

Recent changes to /etc/newsyslog.conf (r340318) will only include files
from the /usr/local/etc/newsyslog.conf.d/ directory which end with
'.conf' and do not beginning with a '.' character.

 ************************************************************************

+The ntpa newsyslog.conf(5) filename has been changed:
+  OLD: ${PREFIX}/etc/newsyslog.conf.d/ntpa
+  NEW: ${PREFIX}/etc/newsyslog.conf.d/ntpa.conf
+
+Any file found at the old location has been automatically moved to
+the new location. This was done to ensure log rotation continued to
+work after change r340318 made to FreeBSD base, where the default
+newsyslog configuration now only includes filenames that end with
+'.conf' and do not begin with '.'.
+
+If you use provisioning/configuration management tools to create or
+edit this file, you will need to change their configuration to use
+the new filename.
