Mantflow only supports wavelet noise, thus the parameter with only one option is no longer useful.

The colons are not necessary in these situations because it's clear
that the label applies to the next group of buttons anyway, and they
add unecessary visual complexity. Committing as part of D9924.
Mainly updated the Mantaflow version. It includes the new viscosity solver plugin based on the method from 'Accurate Viscous Free Surfaces for Buckling, Coiling, and Rotating Liquids' (Batty & Bridson).
In the UI, this update adds a new 'Viscosity' section to the fluid modifier UI (liquid domains only). For now, there is a single 'strength' value to control the viscosity of liquids.
Basic support for velocity updates with the APIC method.
This commit adds APIC to the already existing dropdown menu for the simulation method. The APIC plugin within Mantaflow has been updated to the latest version.

Being able to adjust the distance between fluid and obstacles comes in handy when trying to achieve a fluid motion over inclined obstacles.
Depending on the slope of such obstacles, already small adjustments of this value can help when particles stick to obstacle surfaces (i.e. make particles not stick to obstacles).
- Density, interpolation and slicing options in Volume Object's
Viewport Display are now not aligned to each other as they are not
closely related.
- Changed the enum property for slicing ('Method') to a boolean
property 'Slice' and added a sub-panel for slicing options under
the 'Viewport Display' panel in Volume Object and Fluid for better
clarity.
- Renamed `axis_slice_method` to `use_slice` in the python API for
Volume Object and Fluid.

All the changes made in the branch `soc-2020-fluid-tools` are included in this patch.
**Major changes:**
=== Viewport Display ===
- //Raw voxel display// or //closest (nearest-neighbor)// interpolation for displaying the underlying voxel data of the simulation grids more clearly.
- An option to display //gridlines// when the slicing method is //single//.
==== Grid Display ====
- Visualization for flags, pressure and level-set representation grids with a fixed color coding based on Manta GUI.
==== Vector Display ====
- //**M**arker **A**nd **C**ell// grid visualization options for vector grids like velocity or external forces.
- Made vector display options available for external forces.
==== Coloring options for //gridlines// ====
- Range highlighting and cell filtering options for displaying the simulation grid data more precisely.
- Color gridlines with flags.
- Also, made slicing and interpolation options available for Volume Object.

This commit adds a label on top of the bake operator in modular bake mode. This way users will immediately see if their current settings will allow them to bake noise, meshes or particles after baking the simulation base.
Modular caches for noise, particles and meshes require that additional data is baked (i.e. is resumable option). With this commit users will be explicitly asked to enable this option before being able to bake noise, particles or meshes.
New option that lets users the define the maximum number of fluid particles that will be allowed in the simulation. This can come in handy, for example, to ensure that the particle count will not exceed the hardware capabilities, or to avoid excessive amounts of particles in a scene.
Added an offset field to control when to load the simulation files. Since this is a very small but helpful addition it is in my view safe to commit at this point of the bcon cycle.
This does not work, because the fluid modifier is not called when the
object is e.g. in edit mode. Another possible fix would be to switch
to object mode when baking starts automatically. However, I think it
is reasonable to simply not allow baking while the domain is in edit mode.

This commit makes uses of the new OpenVDB IO in Mantaflow (introduced in 781f783a66ac).
From now on, fluid cache files in OpenVDB format will contain a list of grids per frame (before: one .vdb file per grid per frame). Besides regular grids, particle systems are also stored using OpenVDBs PointGrid data structures.
All older cache formats will remain fully functional:
- Uni caches (.uni) files are still available from the UI and can be used as before
- Raw caches (.raw) are no longer available from the UI, but loading them is still possible
- Old OpenVDB caches (one .vdb per grid) can no longer be baked either, but loading them is still possible.
It is also no longer possible to choose file formats for 'Noise' and 'Particles'. Instead there are now options to set the file format for 'Volumetric' and for 'Mesh' data.
Known issues (planned to be resolved soon):
- OpenVDB files are currently not taking into consideration the clipping value (FluidDomainSettings). Empty cells are therefore being written too. Depending on the scene, this can make file sizes unnecessarily large.
- Domains are not being exported at their world position. Instead they are always clipped to the origin.
This option existed already and was just hidden in the UI. With the new fluids system though, it will only be used for rendering - and not to optimize the cache.
Fluid guiding functionality was broken in the bake / read cache loop in fluid.c. Committing this to the release branch as otherwise fluid guiding would not have worked as expected (i.e. not at all).
This makes the code more consitent with the rest of blender
The `fractions_threshold` was changed to be active than enabled which is
also more consistent. This needs to be changed in other areas also.
