use uint32 for addresses in protobuf msgs

This prevents integer overflows when using addresses > 2GiB, which are
common for x86 operating systems with paging (Linux, Fiasco.OC) or
some test cases on the PandaBoard.

Note that this results in slightly different result table definitions
when automatically translating an experiment's protobuf message in the
DatabaseCampaign.

This change affects all existing protobuf messages to prevent
copy/paste propagation of this issue.
