- Added space below non doc-string comments to make it clear
these aren't comments for the symbols directly below them.
- Use doxy sections for some headers.
- Minor improvements to doc-strings.
Ref T92709
Caused by {rBcf2baa585cc8}.
For Curve Guide force fields to work, the `Path Animation` option has to
be enabled. With it disabled, we are lacking the necessary
`anim_path_accum_length` data initialized [done by
`BKE_anim_path_calc_data`] which `BKE_where_on_path` relies on since
above commit.
Now just check for this before using it - and return early otherwise.
Prior to said commit, `BKE_where_on_path` would equally return early
with a similar message, so that is expected behavior here.

The issue was that where_on_path uses a resampled curve to get the data
from the curve. This leads to disconnects between the curve the user
sees and the evaluated location data.
To fix this we simply use the actual curve data the user can see.
The older code needed a cleanup either way as there were hacks in other
parts of the code trying to work around some brokenness. This is now
fixed and we no longer need to clamp the evaluation range to 0-1 or make
helper functions to make it do what we actually want.

The files are now split up into the following sections:
- `BKE_anim_path.h` and `anim_path.c` for path/curve functions.
- `BKE_anim_visualization.h` and `anim_visualizationanim_path.c` for
animation visualization (mostly motion paths).
- `BKE_duplilist.h` for DupliList function declarations. These were
already implemented in `object_dupli.c`, so they were rather out of
place being declared in `BKE_anim.h` in the first place.
No functional changes.
