This is the conventional way of dealing with unused arguments in C++,
since it works on all compilers.
Regex find and replace: `UNUSED\((\w+)\)` -> `/*$1*/`
Previously removing elements based on a predicate was a bit cumbersome,
especially for hash tables. Now there is a new `remove_if` method in some
data structures which is similar to `std::erase_if`. We could consider adding
`blender::erase_if` in the future to more closely mimic the standard library,
but for now this is using the api design of the surrounding code is used.

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.
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.
