7d8d3e6a2a Add tests for util/vector.h's Cat and Vector (Pieter Wuille)
e65e61c812 Add some general std::vector utility functions (Pieter Wuille)
Pull request description:
This is another general improvement extracted from #16800 .
Two functions are added are:
* Vector(arg1,arg2,arg3,...) constructs a vector with the specified arguments as elements. The vector's type is derived from the arguments. If some of the arguments are rvalue references, they will be moved into place rather than copied (which can't be achieved using list initialization).
* Cat(vector1,vector2) returns a concatenation of the two vectors, efficiently moving elements when relevant.
Vector generalizes (and replaces) the `Singleton` function in src/descriptor.cpp, and `Cat` replaces the function in bech32.cpp
