9be720d85e BLI: support accessing nth last element in Array/Span/Vector
This often helps to make the intend of code more clear compared
to computing the index manually in the caller.

c434782e3a File headers: SPDX License migration
Use a shorter/simpler license convention, stops the header taking so
much space.

Follow the SPDX license specification: https://spdx.org/licenses

While most of the source tree has been included

- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
  use different header conventions.

doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.

See P2788 for the script that automated these edits.

2aff45146f BLI: improve exception safety of Vector, Array and Stack
Using C++ exceptions in Blender is difficult, due to the large
number of C functions in the call stack. However, C++ data
structures in blenlib should at least try to be exception safe,
so that they can be used if someone wants to use exceptions
in some isolated area.

This patch improves the exception safety of the Vector, Array
and Stack data structure. This is mainly achieved by reordering
some lines and doing some explicit exception handling.
I don't expect performance of common operations to be affected
by this change.

The three containers are supposed to provide at least the
basic exception guarantee for most methods (except for e.g.
`*_unchecked` methods). So, resources should not leak when
the contained type throws an exception.

I also added new unit tests that test the exception handling
in various cases.

cc6c52768a BLI: add reverse iterators, iterator constructor and Vector.insert/prepend
The new reverse iterators behave as the reverse iterators for contains from
the standard library. Have a look at the tests to see how to use them.
Using them will hopefully become easier with ranges in C++20.

A Vector can now be constructed from two iterators, which is very common
in the standard library.

New Vector.insert methods allow adding elements in the middle of a vector.
These methods should not be used often in practice, because they has a linear running time.

New Vector.prepend methods allow adding elements to the beginning of a vector.
These methods are O(n) as well.
