Update of submodules.
Sub-repository updates.
Added add-upstream and fetch targets to component/ Makefile - now can easily track upstream branches that haven't been merged fully.
Disabled debug by default in Bird builds (as it disables the fork to background, which then results in bad behavior of ttin scripts). Sigh.
Sub-component update.
6rd -> tunnel renaming effort.
Updated OWRT feed too.
Removed copying of use-pd file - it no longer exists (and is not relevant).
Fixed pa-config handling v.r.t. tunnels.
Adding interfaces we harvest addresses from to the default 'to' list of interfaces to announce to.
Updated the hnet package.
Sub-repo updates.
Sub-module updates.
Updated sub-repos.
Updated sub-repos.
ttin update.
Built bit more recent Buffalo build, and updated config file accordingly.
Netkit update.
Changed default checked out branches to be correct-ish (although we do not strictly speaking follow OWRT AA branch right now, but perhaps I should sync up again).
Added build type specific files directory, and zeroconf-ish Buffalo files (with routed ports etc).
