Alembic export: make the start/end frame default values less reasonable

The old default values (start/end frame = 1) could have been an actually
desired setting (for example when exporting a non-animated model). To
make this worse, this was only interpreted as "start/end of the scene" by
the export operator when running interactively, but not when run from
Python.

By choosing INT_MIN as default it's highly unlikely that the interval
[start, end) was intended as actual export range.

Alembic export: avoid create-and-reset of shared pointer

Constructing the shared pointer where the object is actually allocated
makes the code a bit clearer.

Alembic export: prevent rounding error buildup in frame sample time

Move GHash/GSet/LinkList iterators to BLI files

Those are not depsgraph or C++ specific and can be used by everyone.

Layer collection doversion: Remove "converted from 2.7" from the name

Followup and partial revert from d78b1147bed6a56dc8fbf6bc46e2e29cb7456c2e

Fix UI message (no points and no phrases in tooltips please!).

Depsgraph: Use own implementation of stack rather than the one from STL

This way we always have predictable behavior, especially from the
performance point of view. Additionally, if some bottleneck is found
in stack implementation it'll be easier for us to address.

Tweak UI messgae checking macro, identifiers are not always available...

Silence warning in RNA when building without fluidsim.

Move hash_combine utility function to a more generic place

This way everyone can benefit from it, not only dependency graph.

Fix strict compiler warning in C++ RNA

Hopefully it is supported by all the compilers.

ImBuf: Fix strict compiler warning in Cineon image IO

Audaspace: Don't use strict flags

Cycles: Cleanup, trailing whitespace

Face Maps: custom-data, UI and RNA API

Add face maps, needed for face-map widgets,
only data structure, widgets will be separate commit.

This comes from 'custom-manipulator' branch with only minor changes.

Fix T50775: Missing parenthesis on fluid bake button.

Yep, that got reported... Was slightly more involved than UI message
fixing though: RNA string length getter shall return exact lentgh of
string (same as strlen), not size of allocated buffer to contain it!
Otherwise, NULL final char leaks in and...

Fix T51652: Cycles - Persistant Images not storing images

Denoising was setting session parameters for every frame, which was detected as
a change and therefore caused a resync.

Since the parameter modification change is only needed for viewport rendering
(which doesn't support denoising anyways) and resyncing after a frame change
(which isn't affected by denoising settings), an easy fix is to just ignore
the denoising parameters like it's currently done with the samples.

Revert "Revert "Remove MTexPoly layers""

I reverted this commit by mistake. Sorry :/

This reverts commit 9caf328a7cc55775b740ee4beecf8a77f47d3986.

Eevee: Replace Cubemaps by octahedron maps for env. probes.

This enables us to use 2D texture arrays for multiple probes.
There is a little artifact with very high roughness caused elongated pixel due to the projection (along every 90� meridian).

NDOF: clean up after MinGW removal

Follow up to 9f044cb422c1fc9ad79278092445f612342abb59

These comments described the difference between Microsoft & MinGW's struct definition. Now that we dropped MinGW we don't need to go into these details.
