asterisk users - Apr 2012 - Which file is loading these lines?

When I start asterisk 1.8.10 I see:
    == Parsing '/etc/asterisk/users.conf':   == Found
     -- Registered extension context 'app_dial_gosub_virtual_context';
registrar: app_dial
     -- merging incls/swits/igpats from old(app_dial_gosub_virtual_context) to
new(app_dial_gosub_virtual_context) context, registrar = pbx_config
     -- Added extension 's' priority 1 to app_dial_gosub_virtual_context
     -- Registered extension context 'parkedcalls'; registrar: features
     -- merging incls/swits/igpats from old(parkedcalls) to new(parkedcalls)
context, registrar = pbx_config
     -- Added extension '700' priority 1 to parkedcalls
     -- Registered extension context 'app_queue_gosub_virtual_context';
registrar: app_queue
     -- merging incls/swits/igpats from old(app_queue_gosub_virtual_context) to
new(app_queue_gosub_virtual_context) context, registrar = pbx_config
     -- Added extension 's' priority 1 to
app_queue_gosub_virtual_context

Which file is loading these lines?

Especially I don't get it where the line: 
Added extension 's' priority 1 to app_queue_gosub_virtual_context
Added extension 's' priority 1 to app_dial_gosub_virtual_context

I'm only using extension.conf and don't see any context:
app_queue_gosub_virtual_contex
