Review request for Asterisk Developers.


Bugs: ASTERISK-23128
    https://issues.asterisk.org/jira/browse/ASTERISK-23128


Repository: Asterisk


Description
-------

This change fixes a few memory leaks in the res_ari module:

1. The documentation stated that the JSON message passed to ast_ari_response_ok would have its reference stolen. This did not actually occur. I've changed the code to match the documentation and changed callers accordingly.

2. I've also updated the ast_ari_response_created function to have the same behavior.

3. HTTP response headers were never freed.

4. The variable list for wildcard paths was never freed.

Testing
-------

Ran under valgrind and invoked some ARI operations which cover the various fixed cases. Stopped, confirmed output showed no leaks in ARI. I also ran with MALLOC_DEBUG enabled and did a "memory show summary".


Thanks,

Joshua Colp
