Make MainClock more self-contained and generic by moving logic from the
Config system and to the class itself, while making the class less aware
of how it is used in the config system.
It is slightly dirty to store the initial AudioClock widget name in
MainClock, but less dirty than having to pass the whole name correctly
every time the delta mode changes.
Also avoid confusing use of 'mode', which in AudioClock is used for the
units/formatting of the clock.
We would like to introduce an actual setter, but the most appropriate
name for it was used by something else: the high level callback invoked
when selecting the menu item.
Having current_time as a public alias of the private last_when did not
add any clarity to the abstraction of last_time. A small step, but still
room for improvement.
When selecting "Origin" for the clock, it is expected that it should
work like "Absolute", except measuring from the selected Origin.
Positions to the right of origin should be positive.
However, recently, it got negated. As playback progressed, time got more
and more negative. Fix that by negating again.
The class now has two separate methods for setting a duration or a point
value. They MUST be used appropriately, because their behavior is different.
When ::set_duration() is used in timecode mode, an extent (inclusive-end
length) is shown rather than a length.
Some objects, such as the TimeInfoBox, now deliberately shown an inclusive end
for their "end" clock, but this not universally followed, pending more feedback
from users and investigating of conventions in other DAWs.

Add a function TempoMap::meter_section_at(), similar to
TempoMap::tempo_section_at() but returning the meter section at the given
position, and use this to make editing meter changes from the main clock
work on the meter that's in effect at the current position.
Remove (always false) duration & is_transient and (always true) editable,
with_info & follows_playhead parameters from MainClock constructor, and just
pass the requisite true & false values along to the AudioClock constructor
instead.
