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.

(closes issue http://bugs.digium.com/view.php?id=10668)
Reported by: arkadia
Tested by: murf, arkadia

Options added to forkCDR() app and the CDR() func to
remove some roadblocks for CDR applications.

The "show application ForkCDR" output was upgraded
to more fully explain the inner workings of forkCDR.

The A option was added to forkCDR to force the
CDR system to NOT change the disposition on the
original CDR, after the fork. This involves
ast_cdr_answer, _busy, _failed, and so on.

The T option was added to forkCDR to force 
obedience of the cdr LOCKED flag in the
ast_cdr_end, all the disposition changing
funcs (ast_cdr_answer, etc), and in the
ast_cdr_setvar func.

The CHANGES file was updated to explain ALL
the new options added to satisfy this bug report
(and some requests made verbally and via 
email, irc, etc, over the past months/year)

The 's' option was added to the CDR() func,
to force it to skip LOCKED cdr's in the
chain.

Again, the new options should be totally transparent
to existing apps! Current behavior of CDR,
forkCDR, and the rest of the CDR system should
not change one little bit. Until you add the
new options, at least!

Arkadia tried to warn me, but the code added to ast_cdr_busy, _failed, and
_noanswer was redundant. Didn't spot it until I was resolving conflicts in
trunk. Ugh. Redundant code removed. It wasn't harmful. Just dumb.

Occasionally, the alertpipe loses its nonblocking status, so detect and
correct
that situation before it causes a deadlock.  (Reported and tested by

Flipflop the sections for two options, since the section for 'X' (exit
context)
may otherwise absorb keypresses meant for 's' (admin/user menu).

This should fix the behavior of the 'T' dial feature being passed
incorrectly to the transferee when builtin_atxfers are used.
Also, doing a builtin_atxfer to parking was broken and is fixed here as
well.
