cdr: allow disabling CDR by default on new channels

Adds a new option, defaultenabled, to the CDR core to
control whether or not CDR is enabled on a newly created
channel. This allows CDR to be disabled by default on
new channels and require the user to explicitly enable
CDR if desired. Existing behavior remains unchanged.

+Subject: cdr
+
+A new CDR option, channeldefaultenabled, allows controlling
+whether CDR is enabled or disabled by default on
+newly created channels. The default behavior remains
+unchanged from previous versions of Asterisk (new
+channels will have CDR enabled, as long as CDR is
+enabled globally).
