Summary:                    Incomplete CDR lock
Description: 
This is all about the meaning of AST_CDR_FLAG_LOCKED flag for CDR. 
I assume if CDR has this flag set then it wont be updated anymore by any
ast_cdr_ functions except cases when we force such update. ast_cdr_reset()
is example of function which allows to update locked CDRs if special flag
is given.

Based on this assumption I prepared the patch with such changes:

  ast_cdr_setvar() - not allowed to touch locked CDRs. I don't see any
cases when we need to change locked CDRs too. Not touching locked CDRs is
helpfull when ForkCDR being used and every new CDR may have different
custom variables.

  ast_cdr_answer() - don't change status of locked CDRs. That might be
helpfull when we have a chain of CDRs for one incoming call for which we
perform several tries to make outgoing call. Every outgoing attempt may
finish with its own completion code. And if the final attempt is 'answered'
then we have only one CDR with 'answered' status. All other will keep
connection error codes which is very helpful for error monitoring.

 ast_cdr_end() - don't change locked CDRs by the same reason as
ast_cdr_answer()

As there will be no changes in CDR after lock, app_forkcdr.c should be
updated to end original locked CDR.
Also it'll be great to make optional cdr reset in this application, but
thats a theme for another patch.

Reported by: arkadia

These changes:

1. revert the changes made via bug 10668; 
   I should have known that such changes,
   even tho they made sense at the time,
   seemed like an omission, etc, were actually
   integral to the CDR system via forkCDR.
   It makes sense to me now that forkCDR didn't
   natively end any CDR's, but rather depended
   on natively closing them all at hangup time
   via traversing and closing them all, whether
   locked or not. I still don't completely 
   understand the benefits of setvar and answer
   operating on locked cdrs, but I've seen 
   enough to revert those changes also, and
   stop messing up users who depended on that
   behavior. bug 12726 found reverting the changes
   fixed his changes, and after a long review
   and working on forkCDR, I can see why.
2. Apply the suggested enhancements proposed
   in 10668, but in a completely compatible
   way. ForkCDR will behave exactly as before,
   but now has new options that will allow some
   actions to be taken that will slightly 
   modify the outcome and side-effects of
   forkCDR. Based on conversations I've had 
   with various people, these small tweaks
   will allow some users to get the behavior
   they need. For instance, users executing
   forkCDR in an AGI script will find the
   answer time set, and DISPOSITION set, 
   a situation not covered when the routines
  were first written.
3. A small problem in the cdr serializer
   would output answer and end times even
   when they were not set. This is now 
   fixed.
