Paul Davis b936fd12cd temporal: reset the tempo map in sections bounded by BBT markers (if any) 
This avoids total SNAFUs caused by the impossibility of globally ordering

Paul Davis e9f71824a1 temporal: change API for TempoMap::stretch_tempo() 
This will likely be modified because it is actually impossible to do
what this code is attempting to do.

Paul Davis 5b6bc3f358 Revert "tempo map: use lookup tables to speed up time conversions" 
This reverts commit 644ebe37a8.

Adding entries to the lookup table is (a) not thread safe (b) not appropriate
from RT context.

Paul Davis 92bd8461ca tempomap: provide improved reftime() method for TempoMetric 
This now looks backwards in time for a BBT_Marker or the start of the
tempo map, whichever comes first.

Paul Davis 62d4e0789a tempo map: fix error in TempoMap::copy_points() that fails to reset _map ptr 
This left the _map ptr of all points in a copy of a map pointing
to an old/dead TempoMap.

Fix grid when tempo marker is not on a mod_bar/beat_div 
Previously the current iterator bbt was moved to p->bbt().

From then on, no grid line is reached if the point p is not on
a bar and mod_bar != 0 or the point is not on an expected beat_div.

e.g. when using bbt += mod_bar, and a tempo-change is at 5|2|0.
iterations continues 6|2|0 7|2|0  is_bar() is always false
and no more grid-lines were added.

Rather than trying
   bbt = round-up-to-next-grid-mod-div
and then finding the metric for that position, this
approach only does the latter using the already incremented
BBT position.

Paul Davis 39c324b620 temporal: fix ::get_grid() crash condition 
We cannot call TempoMetric::superclock_at (BBT_Time) if the BBT time is beyond
the range of the current TempoMetric. We must discover that *before* we make
that call, not as part of the test to see if we've exceeded the range.

Paul Davis d77db816de temporal: reimplement and tweak API of TempoMap::get_grid() 
There were many logical errors in the previous implementation. This one is
simpler to read, and appears to work much better.

It also allows the caller to specify the quarter-note subdivision to use when
generating the grid, rather than choosing only between some bar modulo or
quarter notes.
