temporal: TempoMap::use() returns a const ptr to enforce semantics (library version)
...
This commit leaves two issues outstanding:
1. unclear/ugly semantics for drag operations that reset the GUI thread's tempo map to the writable copy
2. undo/redo for the tempo map
These will be addressed in future commits

superclock_ticks_per_second: use an (inline) accessor, change value
...
We do not want a value as large as the previous one, which limits the time
range that can be represented in 62 bits unnecessarily. The new value is
9 times smaller than the previous value, and loses only 384000 as a significant
factor.
This commit also switches to using an (inline) accessor for superclock_ticks_per_second,
making it possible in debug/testing phases to spot early/illegal uses of the value.

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).

...
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.

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.

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

Temporal: remove constructors accepting scalar values from timepos_t/timecnt_t and force use of factory methods
...
This allows us to differentiate between superclock_t and samplepos_t (and related types) which are all typedef'ed to the
same underlying primitive C++ type. Without this, it would be impossible for the compiler or someone reading the code
to know whether a scalar passed to a constructor for a timeline type is in units of samples or superclocks
