`git__timer` is now `git_time_monotonic`, and returns milliseconds since an arbitrary epoch. Using a floating point to store the number of seconds elapsed was clever, as it better supports the wide range of precision from the different monotonic clocks of different systems. But we're a version control system, not a real-time clock. Milliseconds is a good enough precision for our work _and_ it's the units that system calls like `poll` take and that our users interact with. Make `git_time_monotonic` return the monotonically increasing number of milliseconds "ticked" since some arbitrary epoch.
