Summary:                    [patch] Serious problem with pattern matching
(regression in https://issues.asterisk.org/view.php?id=15421)
Description: 
Hi, with the following dialplan:

[context]
exten => _[23],1,Set(category=NL-normal)
exten => _[45],1,Set(category=NL-normal)
exten => _[67],1,Set(category=NL-normal)
exten => _[89],1,Set(category=NL-normal)
exten => _X,1,Set(category=NL-unknown) ; (catch all)

_X sorts above [23] since asterisk 1.6.1.10.

Look at the following outputs:


[Asterisk 1.6.1.9]

*CLI> dialplan show context
[ Context 'context' created by 'pbx_config' ]
  '_[23]' =>        1. Set(category=NL-normal)                   
[pbx_config]
  '_[45]' =>        1. Set(category=NL-normal)                   
[pbx_config]
  '_[67]' =>        1. Set(category=NL-normal)                   
[pbx_config]
  '_[89]' =>        1. Set(category=NL-normal)                   
[pbx_config]
  '_X' =>           1. Set(category=NL-unknown)                  
[pbx_config]

[Asterisk 1.6.1.10 and above, up to -svn]

*CLI> dialplan show context
[ Context 'context' created by 'pbx_config' ]
  '_[89]' =>        1. Set(category=NL-normal)                   
[pbx_config]
  '_X' =>           1. Set(category=NL-unknown)                  
[pbx_config]
  '_[67]' =>        1. Set(category=NL-normal)                   
[pbx_config]
  '_[45]' =>        1. Set(category=NL-normal)                   
[pbx_config]
  '_[23]' =>        1. Set(category=NL-normal)                   
[pbx_config]


In my real world case:
exten => _+31X!,2,Set(category=NL-unknown) ; (catch all)
sorts above:
exten => _+31[2357]XXXXXXXX,2,Set(category=NL-normal)
yielding NL-unknown for normal Dutch phone numbers.


As far as I can see, this bug was introduced by the patch applied to fix
https://issues.asterisk.org/view.php?id=15421. (It touches the ext_cmp stuff and
was introduced in 1.6.1.10.)

I'll try to come up with more detailed information. (But I've flagged it
as Major in the mean time as I believe it to be a serious issue.)
