This is handy if you have a u32 and want a u32 and don't want to take a
detour through many layers of abstraction elsewhere in the std.hash
namespace.

Tests that only reference decls for the purpose of analyzing more tests
should be unnamed, otherwise trying to filter for just a referenced test
can become impossible depending on the names.
We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.
SipHash *is* a cryptographic function, with a 128-bit security level.
However, it is not a regular hash function: a secret key is required,
and knowledge of that key allows collisions to be quickly computed offline.
SipHash is therefore more suitable to be used as a MAC.
The same API as other MACs was implemented in addition to functions directly
returning an integer.
The benchmarks have been updated accordingly.
No changes to the SipHash implementation itself.
