Subject: Clean up resources in features on exit
X-Git-Tag: 11.5.0-rc1~48
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=65c34c59de686dca8e92f2ffb9695791d05a362e;p=thirdparty%2Fasterisk.git

Clean up resources in features on exit

This patch cleans up two things features:
* It properly unregisters the CLI commands that features registered
* It cancels and performs a pthread_join on the created parking thread. This
  not only properly joins a non-detached thread, but also prevents disposing
  of the parking lots prior to the parking thread completely exiting.

(closes issue ASTERISK-21407)
