Minor edits of python class documentation (regarding ID tagging)

Calculate auto normalization maximum from keyframes within range if
preview is on

Nodes: Remove hardcoded BLENDER_MAX_THREADS number of threads

Use actual available number of threads now, which will make it easier
to increase max number of threads, without having some sloppy memory
usage and without doing some redundant checks on thread data which was
never used.

Be a bit more specific in the message.

Windows:

Only print backtrace on debug builds, since on release builds there is
only some useless output from a python library and fftw.

Depsgraph debug: Remove hardcoded array of BLENDER_MAX_THREADS elements

Allocate statistics array dynamically, so increasing max number of threads does
not increase sloppyness of the memory usage.

For the further cleanups: we can try alloca-ing this array, but it's also not
really safe because we can have quite huge number of threads in the future.
Plus statistics will allocate memory for each individual entry, so using alloca
is not going to give anything beneficial here.

Fix adding to paint-curves from the first point

- add_index now works when selecting the first point.
- sliding now selects the correct handle.

Fix hair random rotation limited to 180 degrees

The issue was caused by phase being limited from 0 to 1, which gave only
0..M_PI distribution which is not good enough for good randomness.

Now the phase is being randomized across full 0..2*M_PI range.

Make python gotchas more clear (regarding handling of stale data)

Fix T44361: array modifier "fit curve" mode not working properly

'tot_length / step_length' gives the number of 'segments', not the number of
copies - we have to add 1 here.

BMesh: diagram for dyntopo edge subdiv

Py API: default arg for location_3d_to_region_2d

This function could return None for points behind the view,
note this in the doc-string and add an optional fallback argument.

GHash: use unsigned int for ghash_size

Dyntopo: redundant length check subdividing edges

BMesh: minor optimization counting adjacent data

add BM_***_count_is_over(), _count_is_equal()

Useful if we only want to know if the count is a smaller value.
