Review request for Asterisk Developers.


Changes
-------

Point out other fixes as a result of the matching cleanup.


Summary (updated)
-------

The '-' char is supposed to be ignored by the dialplan pattern matching.  Unfortunately, it's treatment is not handled consistently throughout the extension matching code.

* Made the old exten matching code consistently ignore '-' chars.

* Made the old exten matching code consistently handle case in the matching.

* Made ignore empty character sets.

* Fixed ast_extension_cmp() to return -1, 0, or 1 as documented.  The only user of it in pbx_lua.c was testing for -1.  It was originally returning the strcmp() value for less than which is not always going to be -1.


This addresses bug ASTERISK-19205.

Testing
-------

The failing patterns in ASTERISK-19205 now pass except for the invalid test of goto(foo-,1) for exten "_foo.".


Thanks,
