250a5442cf BLI: add LinearAllocator.construct_array method
Previously, one could allocate an array, but not construct its
elements directly. This method just adds some convenience.

649916f098 BLI: make it harder to forget to destruct a value
Instead of returning a raw pointer, `LinearAllocator.construct(...)` now returns
a `destruct_ptr`, which is similar to `unique_ptr`, but does not deallocate
the memory and only calls the destructor instead.

456d3cc85e BLI: reduce wasted memory in linear allocator
The main change is that large allocations are done separately now.
Also, buffers that small allocations are packed into, have a maximum
size now. Using larger buffers does not really provider performance
benefits, but increases wasted memory.

91694b9b58 Code Style: use "#pragma once" in source directory
This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.

This patch has been generated by P1561 followed by `make format`.

8cbbdedaf4 Refactor: Update integer type usage
This updates the usage of integer types in code I wrote according to our new style guides.

Major changes:
* Use signed instead of unsigned integers in many places.
* C++ containers in blenlib use `int64_t` for size and indices now (instead of `uint`).
* Hash values for C++ containers are 64 bit wide now (instead of 32 bit).

I do hope that I broke no builds, but it is quite likely that some compiler reports
slightly different errors. Please let me know when there are any errors. If the fix
is small, feel free to commit it yourself.
I compiled successfully on linux with gcc and on windows.

d64803f63b Cleanup: Use trailing underscore for non-public data members
This makes the code conform better with our style guide.

e44045745d BLI: don't pass const pointers to placement new operator

f7c0f1b8b8 BLI: rename ArrayRef to Span
This also renames `MutableArrayRef` to `MutableSpan`.
The name "Span" works better, because `std::span` will provide
similar functionality in C++20. Furthermore, a shorter, more
concise name for a common data structure is nice.

9bb7d6ed68 BLI: put C++ data structures in "blender" namespace instead of "BLI"
We plan to use the "blender" namespace in other modules as well.

d8678e02ec BLI: generally improve C++ data structures
The main focus here was to improve the docs significantly. Furthermore,
I reimplemented `Set`, `Map` and `VectorSet`. They are now (usually)
faster, simpler and more customizable. I also rewrote `Stack` to make
it more efficient by avoiding unnecessary copies.

Thanks to everyone who helped with constructive feedback.

Approved by brecht and sybren.
