[Matthias Schiffer: squash, use safe_realloc]
This new version of the autoupdater is implemented in C instead of Lua,
allowing us to interface with libuclient (HTTP downloads) and libecdsautil
(signature checks) directly instead of spawning external processes,
saving RAM and making error handling more robust.
