fix: mesh was messed up if you used no pointsource, just the islands.

Big refactor of filelisting in filebrowser - decouple os/fs-related direntry from actual blender listing.

Main idea is that direntry had quite a bit of things already absolutely useless
in the mere 'file listing' context (image pointer, void 'data' pointer, etc.).

On the other end, to handle future asset stuff, we need *more* 'meta data' for our 'files'
(tags, variants, revisions...).

Further more, we need all this to be easily usable through RNA, i.e. we need it to
be defined in DNA.

So instead of trying to use direntry in DNA, mixing low-level system stuff like stat
where we do not want to see it, we define our own 'file' representation,
with only what we really need (who cares about chars or block or dev files in filebrowser?
we only need to know whether it's a regular file or a directory, period).

That way, low-level dirlisting remains clean, and we can easily extend our own
data as needed.

Note this new code works, does not crash (so far...) nor memleak, but it
needs quite a bit of work still, we are still storing useless stuff in direntry
(all those strings representing modes, size etc.!), and mem handling
during dir/lib listing is confusing at best (would like to use a memarena
or mempool here, but it's not that easy).

added greasepencil edge fracture, the direction of cutting is currently limited to global X, Y or Z axis

Merge branch 'master' into asset-experiments

Also move new gpu object to derived mesh - we can probably do a few
abstractions here, but gpuObject creation is a bit derivedmesh type
specific (each DM has its own way to calculate vertices needed etc).

Move data copying function from gpu_buffers.c to cdderivedmesh.c (as it
should be, since it's specialized to this derivedmesh type)

New option "use signed distance" for force fields with "surface" shape.

By default a surface-based force will push things away from the surface
in both directions, regardless of whether a point is "inside" or
"outside" (judging by the surface normal). The new option makes a force
field always push things away in the direction of the normal, so that
it becomes less likely to get points "trapped" inside a mesh object.

fix: cutter groups should work mostly now

Always make sure the surface modifier has tessfaces available for
building the BVH.

A long long time ago (rB3816554cbc1a40dc5199c8e56e45817ec09128d5) it
was coded such that edges would be used instead of faces for surface
distance calculation. This is pretty much never what you actually want.

fix : set some better default values for Fractal Boolean, so the object / default cube should not explode automatically, but its far from optimal still this way.... (active objects with Mesh Shape cause unstable simulation behavior)

Merge branch 'master' into gooseberry

fix : forgot to set inner material with fractal boolean

added cutter groups, this is intended to define custom sets of objects to make boolean cuts against, but its still WIP, as it still fails too often

Merge branch 'master' into gooseberry

Merge branch 'master' into GPU_data_request

Removed unused (and broken) functions for getting the number of written
cache samples.

This can be done more reliably using Alembic schemas.

Optimization for particle path cache reading.

The pathcache data structure is really not very good. Using pointers to
small per-particle arrays leads to fragmentation and unnecessary pointer
indirection. With the new optimizations walking over this buffer is a
bit faster, but still not close to how fast Alembic could deliver the
data.
