Subject: Properly clean up manager resources on exit
X-Git-Tag: 10.11.0-rc1~9
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=64f4ef4eb75f70da3366278fd6c9d83760ffc399;p=thirdparty%2Fasterisk.git

Properly clean up manager resources on exit

This patch does two things:
1) It properly unregisters the manager CLI commands
2) It cleans up AMI users on exit.  Prior to this patch, the AMI users
   were not being disposed of properly, resulting in a memory leak.

(closes issue ASTERISK-20646)
