Our main function, though accurate on all platforms, can be very
slow on 32-bit hosts. This one is faster on all 32-bit hosts, and
accurate everywhere except apple, where it will typically be off by
1%. But since 32-bit apple is a relic anyway, I think we should be
fine.
Previously were using this value to have a cheap highish-resolution
timer. But we were only using it in one place, and current dogma is
to use monotime_coarse_t for this kind of thing.
This part of the code was the only part that used "cached
getttimeofday" feature, which wasn't monotonic, which we updated at
slight expense, and which I'd rather not maintain.
Previously, we were ignoring values _over_ EPSILON. This bug was
also causing a warning at startup because the default value is set
to -1.0.
Fixes bug 25577; bugfix on 6b1dba214d. Bug not in any released tor.
Two helper functions to enable an event and disable an event which wraps the
launch and destroy of an event but takes care of the enabled flag.
They are also idempotent that is can be called multiple time on the same event
without effect if the event was already enabled or disabled.

In case we transitionned to a new role in Tor, we need to launch and/or
destroy some periodic events.

In tor, we have a series of possible "roles" that the tor daemon can be
enabled for. They are:
Client, Bridge, Relay, Authority (directory or bridge) and Onion service.
They can be combined sometimes. For instance, a Directory Authority is also a
Relay. This adds a "roles" field to a periodic event item object which is used
to know for which roles the event is for.
The next step is to enable the event only if the roles apply. No behavior
change at this commit.

No behavior change, just to make it easier to find callbacks and for the sake
of our human brain to parse the list properly.
