Keymap: preference to swap 3D orbit/pan actions

Requested by @pepeland for grease pencil/2D usage.

Keymap: preference for relative/absolute Alt-MMB navigation

Original request from Hjalti was to set absolute view axis,
so make this an option.

Fix: Build error on windows in bf_intern_mantaflow

bf_intern_mantaflow lacked the `-DOPENVDB_STATICLIB` define
causing it to dynamically import openvdb, linked against
our static libs a happy time was not had by the linker.

Fluid: Optimization for fluid domain obstacle boundary handling

This fix should especially improve liquid obstacles boundaries, i.e. help with the problem of particles sticking to the surface.

Fluid: Hide Advanced cache options

The Manta script export should not be visible in the UI. At least not to normal users. The export feature is only useful for developers.

Readfile: refactor/factorize more handling of common ID data.

- Move handling of private ID data (nodetree and master_collection)
under generic ID code. This shortens code a bit, but mostly avoids having
to modify all type-specific callback functions if/when we have to add
generic processing to IDs there.

- Seriously factorize `expand_xxx` area, in the same way we were already
doing in `direct_link_xxx` and `lib_link_xxx` areas.

Note that this actually also fixes some bugs (at least, potential ones),
like e.g. missing call to expand_id() for our beloved 'private ID'
(nodetrees & co), in current master code...

NodeTree: Add access to the address of an ID's nodetree pointer.

OpenVDB: Fix IOError in try catch statement

Broader exception handling for OpenVDB IO errors.

Fluid: Fixed slow cache loading for smoke data

Cache files are currently loaded via the Manta Python API. With very big caches this can slow down the viewport playback. Especially smoke simulations, which just load grids and no meshes, can suffer from this. This fix solves this problem by directly loading the cache files from disk (no Python). This fix has been in the works for some time. The developer of this patch is ready to handle any potential fall-out of this patch quickly.

Fluid: Removed UI locks for cache file types

Caches that haven't been baked yet should not be locked.

Particle: Added sanity in particle system removal function

Added a NULL check since psys_get_modifier() might also return a NULL pointer.

Fix (unreported) timeline missing refresh on VSE selection change

Keyframes and channels were not updating immediately (you had to enter
channel and main regions with the mouse to force a redraw).

Cleanup: refactor default materials and shader nodes

Smooth Modifier add invert vgroup option

Adds the invert vertex group option to the smooth modifier.

Setup same way as previous modifiers.

Curve Modifier add invert vgroup option

Adds the invert vertex group option to the Curve modifier.

Adds a short flag and char pad to the Curve modifier DNA. Passes the flag into the curve_deform_verts function as the weight values are found there and not in the modifiers .c file.
