/* Three routines were "fixed" via 10668, and later shown that
users were depending on this behavior. ast_cdr_end,
ast_cdr_setvar and ast_cdr_answer are the three routines.
While most of the other routines would not touch
LOCKED cdr's, these three routines were designed to
operate on locked CDR's as a matter of course.
I now appreciate how this plays with the ForkCDR app,
which forms these cdr chains in the first place.
cdr_end is pretty key: all cdrs created are closed
together. They only vary by start time. Arithmetically,
users can calculate the subintervals they wish to track. */
