`CallDescriptions` have a `RequiredArgs` and `RequiredParams` members,
but they are of different types, `unsigned` and `size_t` respectively.
In the patch I use only `unsigned` for both, that should be large enough
anyway.
I also introduce the `MaybeUInt` type alias for `Optional<unsigned>`.
Additionally, I also avoid the use of the //smart// less-than operator.
template <typename T>
constexpr bool operator<=(const Optional<T> &X, const T &Y);
Which would check if the optional **has** a value and compare the data
only after. I found it surprising, thus I think we are better off
without it.

Previously, CallDescription simply referred to the qualified name parts
by `const char*` pointers.
In the future we might want to dynamically load and populate
`CallDescriptionMaps`, hence we will need the `CallDescriptions` to
actually **own** their qualified name parts.

This patch introduces `CallDescription::matches()` member function,
accepting a `CallEvent`.
Semantically, `Call.isCalled(CD)` is the same as `CD.matches(Call)`.
The patch also introduces the `matchesAny()` variadic free function template.
It accepts a `CallEvent` and at least one `CallDescription` to match
against.

Sometimes we only want to decide if some function is called, and we
don't care which of the set.
This `CallDescriptionSet` will have the same behavior, except
instead of `lookup()` returning a pointer to the mapped value,
the `contains()` returns `bool`.
Internally, it uses the `CallDescriptionMap<bool>` for implementing the
behavior. It is preferred, to reuse the generic
`CallDescriptionMap::lookup()` logic, instead of duplicating it.
The generic version might be improved by implementing a hash lookup or
something along those lines.

`CallDescriptions` deserve its own translation unit.
This patch simply moves the corresponding parts.
Also includes the `CallDescription.h` where it's necessary.
