-- There a bunch of places where the result of pbx_builtin_getvar_helper()
gets stored and used. This is not threadsafe. This code should be replaced
with the following thread-safe version:
const char *var;
ast_channel_lock(chan);
if ((var = pbx_builtin_getvar_helper(chan, "MYVAR"))) {
var = ast_strdupa(var);
}
ast_channel_unlock(chan);
-- Convert all existing uses of astobj.h to astobj2.h
-- (chan_sip already in progress in a branch)
