CLEANUP: global: reorder some fields to respect cache lines

Some entries are atomically updated by various threads, such as the
global counters, and they're mixed with others which are read all the
time like the mode. This explains why "perf" was seeing a huge access
cost on global.mode in process_stream()! Let's reorder them so that
the static config stuff is at the beginning and the live stuff is at
the end.
