Subject: create the IAX2 processing threads as background threads so they will use smaller... 
X-Git-Tag: 1.4.1~328
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=aed14672817f79bdb547e5c507302a1a618f3bb6;p=thirdparty%2Fasterisk.git

create the IAX2 processing threads as background threads so they will use smaller stacks
when we create a dynamic thread, put it on the dynamic_list right away so we don't lose track of it
