ui: provide a mechanism to track and log blocked time
We want to log the time Mercurial spends trapped in things outside
programmatic control. Provide a mechanism to give us both command runtime
and as many different sources of blocking as we deem useful.

mercurial: switch to util.timer for all interval timings
util.timer is now the best available interval timer, at the expense of not
having a known epoch. Let's use it whenever the epoch is irrelevant.

util: introduce timer()
As documented for timeit.default_timer, there are better timers available for
performance measures on some platforms. These timers don't have a set epoch,
and thus are only useful for interval measurements, but have higher
resolution, and thus get you a better measurement overall.
Use the same selection logic as Python's timeit.default_timer. This is a
platform clock on Python 2 and early Python 3, and time.perf_counter on Python
3.3 and later (where time.perf_counter is introduced as the best timer to use).
