change time_monotonic_ms() from time_t to int64_t

Browse Source 
time_monotonic_ms values did wrap every ~24 days, leading to problems
in code that did not cope with that. Instead of fixing all places where
relative comparisons with time_monotonic_ms() are made, just use a
bigger datatype. Convert all users to the new type.
