When using FModifier `Restrict Frame Range`, the resulting influence was
zero being exactly on `Start` / `End` range borders (so borders were
**exclusive**).
This made it impossible to chain FModifers together (forcing the user to
specify values slightly below the desired border in following
FModifiers).
This is now corrected to be **inclusive** on Start / End range borders.

After

Testfile
{F10234866}
In the case of touching open borders (so [frame A frame B] followed by
[frame B frame C]) both modifiers are evaluated (in stack order).
If the later modifier has full influence (and is not additive) this simply
means the result is the same as the later modifier's value.
If influences below 1 are used (or modifiers are additive) both modifier's
values are interpolated/added accordingly.
technical notes:
- this was caused by the introduction of FModifier Influence/BlendIn-Out
in rB185663b52b61.
- for comparison, see other occurrences of
`FMODIFIER_FLAG_RANGERESTRICT`.
- the following conditions in `eval_fmodifier_influence` for blend in/
out have been changed accordingly.

This patch implements the list panel system D7490 for FCurve modifiers.
The UI layouts are updated to make use of subpanels and to be consistent
with the rest of the interface, and easier to understand.
See the differential revision for screenshots.
This commit also significantly cleans up the FModifier UI code, and
improves, mainly by replacing the old button creation code is with
the newer interface API using RNA. In turn there is a bit of complexity
added because each FModifier has a separate panel.
Although reordering of FModifiers was not implemented before, we get
drag and drop basically for free here, so it is also included.
As noted in some older to do tasks, FModifiers aren't evaluated
in perfect order, which may be a point of improvement for the future.

Use common prefix as this collided with existing API's (eg BLI_voronoi).
Also expand some non-obvious abbreviations:
- 'g' -> 'generic'
- 'vl' -> 'variable_lacunarity'
- 'V' -> 'v3'
Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

This also makes `IDP_CopyProperty` the "opposite"
of `IDP_FreeProperty`, which is what I'd expect.
Two refactoring steps:
* rename IDP_FreeProperty to IDP_FreePropertyContent
* new IDP_FreeProperty function that actually frees the property

Previously, when a fcurve modifier used storage,
many heap allocations were done.
This caused major slowdowns as described in T63656.
Furthermore, the storage usage was a special case only
used by the Cycles modifier. This refactor makes
storage usage the "normal" case.
That reduces the overall complexity.
The storage is stack allocated now.
The framerate on the provided test scene went up from ~5 fps to ~16 fps.

BF-admins agree to remove header information that isn't useful,
to reduce noise.

Developers should add non license comments as separate comment blocks.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
Cyclic extrapolation is implemented as an f-curve modifier, so this
technically violates abstraction separation and is something of a hack.
However without such behavior achieving smooth looping with cyclic
extrapolation is extremely cumbersome.
The new behavior is applied when the first modifier is Cyclic
extrapolation in Repeat or Repeat with Offset mode without
using influence, repeat count or range restrictions.
This change in behavior means that curve handles have to be updated
when the modifier is added, removed or its options change. Due to the
way code is structured, it seems it requires a helper link to the
containing curve from the modifier object.

Noisy change, but safe, and better do it sooner than later if we are to
rework copying code. Also, previous commit shows this *is* useful to
catch some mistakes.
- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.
When the keyframes at either end of the source curve don't lie on exact frame boundaries,
this casued problems with the Cycles F-Modifier, as part of the cycle would get chopped
off.
This was caused by float -> integer truncation that was occurring, since one variable
was of the wrong type. The problem here wasn't discovered until now (thanks to gcc's
invalid-type warnings on printf's) as in standard usage, we can safely assume that all
keyframes are strictly on frame boundaries.
FCurve Noise Modifer now has an extra float property which offsets the noise in time.
This is useful for creating follow through in procedurally animated noise.
For example, if you've used a noise modifier on a parent bone to add additional movement,
a quick and easy way to add overlapping motion is to create copies of that modifier on
its children, and then offset the time those curves play at. See this in action at:
