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.
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.
Copyright-holder and year information is extracted from git log.
git history begins in 2005. So (C) from 1998..2005 is lost. Also some
(C) assignment of commits where the committer didn't use --author.

and video in order to keep the legible
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.
