6e404ea7bf tempomap: reimplement TempoMap::bbt_walk()
This still needs work to deal correctly with negative (backwards/earlier)
walks.

180c1d7759 tempo map: slight reorganization of ::get_grid
This avoids resetting beats based on superclocks in case where we
already do the opposite.

b3451f4055 tempo map: fix computation of superclocks_per_note_type_at()
Code used position as an absolute, rather than offset from the point
that defines tempo. It worked if the point was at zero, but not
otherwise.

a417cbae4b tempo map: fix a potential bug (not seen in the wild) when generating the grid
the "p" variable could point to _points.end(), so we cannot indirect and use
p->sclock() value unconditionally.

1ba2e28d6f tempo map: fix grid generation with ramped tempos
The old code used the instantaneous tempo at T0 to compute where the next
quarter note would be. This is incorrect, since the tempo is
changing (continuously, for now) during the time represented by that quarter
note. Instead, we need to add a quarter note (or technically, whatever the
tempo note type is) to get a new position in beats, then compute the superclock
time at that location (which will use our equations for tempo, including the
use of omega, the ramp factor).

fb2281129a temporal: add clarifying comments to TempoMap::remove_*()
These comments should correct an impression left in the commit message for
6e9e28343bc3695d that there may be some sort of problem with synchronization
of TempoMap changes. The actual problem is that TempoMap edits are done using
RCU, so the modifications are performaned using a copy of the map, but with
map elements taken from the pre-copy version.

8a59f3fe8e temporal: fix issue with removal of tempo, meter and bartime points
The correct algorithm is to traverse the type-specific list of points,
find the point (if any) whose time matches that of the argument (because
we do not allow multiple points of the same type at the same time), and
then use that discovered point from the _points list.

This approach is required because the actual argument may no longer be
in the tempo map (due to a change made by another thread). The lack of
sync, however, needs investigation.

5b5ca546e0 temporal: fix incorrect implementation of TempoMap::tempo_map()
std::lower_bound() is not appropriate here. We need to find the first
TempoPoint after the given time, then return the one before that.

4376185a6b temporal: fix TempoPoint::superclock_at (Beats)
a negative beat position needs to be legal, so the assert was moved and modified. The only check
for a negative value is that the TempoPoint being used is at absolute zero.

This check might turn out to be wrong in the future, but for now we still require a tempo and
meter point at absolute zero

Fix --no-nls compilation 1/2 -- #8802
pbd/i18n.h MUST NEVER be included from header files and always be
the last include. This is because `_` is declared other headers
notably boost and some apple headers.

leading to issues like
