(closes issue #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!

* PrivacyManager now takes an option where you can specify a context where the
given number will be matched. This way you have more control over who is allowed
and it stops the people who blindly enter 10 digits.
* ForkCDR has new options: 'a' updates the answer time on the new CDR; 'A' locks
answer times, disposition, on orig CDR against updates; 'D' Copies the disposition
from the orig CDR to the new CDR after reset; 'e' sets the 'end' time on the
original CDR; 'R' prevents the new CDR from being reset; 's(var=val)' adds/changes
the 'var' variable on the original CDR; 'T' forces ast_cdr_end(), ast_cdr_answer(),
_busy(), failed(), etc, to all obey the LOCKED flag on cdr's in the chain, and
also the ast_cdr_setvar() func.

"Detailed Behavior Description:\n"
"First, this app finds the last cdr record in the list, and makes\n"

"Next, this new record is linked to the end of the cdr record list.\n"

"Next, if the 'e' option was specified, the 'end' time for the original\n"
