Port mball_to_mesh to use polys.

Fix for [#30445] Particle simulation, rekey crashes blender
- Entering particle mode crashed due to missing checks if a particle didn't have any baked keys.
- The rekey functionality is only supported for hair, so replaced the operator poll function with the correct one.
- Also replaced a couple of other "only hair" operator poll functions to the correct ones.

Fix #30590: Crash in multires when undoing extrude [File incl.]

Missed initialization of hidden array when copying mdisps data from
one face to another.

temp disable inset boundary option, it can make invalid meshes, need to look into this further.

replace SETCOL defines with inline function: rgba_char_args_set

rename define BM_INLINE -> BLI_INLINE to avoid confusion with bmesh defines.

Fix uninitialized variable in multires apply base.

Reported on BlenderArtists by Guffy, was causing ugly spikes in lower
levels.

py/rna api - fix for an empty enum flag with no members being displayed as {}, now check for this case and display as set()

fix [#30589] RNA function descriptions not showing in Python console on autocomplete

show rna function description and arguments now.

fix [#30583] very old blend files are loading post-bmesh with no face/uv information, just wires

versioning code called a customdata update function which ended up clearing tessfaces - before converting polygons to tessfaces.
Added check so tessfaces aren't cleared when there are no polygons.

style cleanup

Make collision function more general so it can be used by other modifiers, too. [This is preparation work for animated smoke collision]

style cleanup

compile fix: linux BLI_gzopen declare was conflicting.

py api:
fix for collection functions not showing up in __dir__,

eg, console autocomplete didnt show up bpy.data.libraries.load

also fix refcounting leak with returning attributes from collections.

Adds support for utf paths on Windows.

Not all file formats/calls are supported yet. It will be expended.

Please from now on use BLI_fopen, BLI_* for file manipulations.
For non-windows systems BLI_fopen just calls fopen.
For Windows, the utf-8 string is translated to utf-16 string in order to call UTF version of the function.

real fix for booleans and face shading this time.

CDDM_tessfaces_to_faces wasbt updating the polyindex (missed incrementing the polyindex pointer).

also added an assert so non release builds will complain when CDDM_calc_edges_tessface() needs to run before CDDM_tessfaces_to_faces().

Some advanced particle rotation modes and reorganization of the rotation panel:
- More angular velocity modes to support creative effects.
- Renamed "Initial Rotation" to "Initial Orientation" to better reflect the functionality
- Renamed "Spin" angular velocity mode to "Velocity".
- Organized the rotation panel a bit better.
- Also some better names and tooltips for the different rotation values.

CDDM_calc_edges_tessface was being called twice for boolean and explide modifiers, now leave it up to the caller to run.

partial fix for bug where booleans were using invalid face/poly normals.

the problem remains (though not quite as bad) but think this is because of a bug elsewhere.
