Just casting a void* to a T* and dereferencing it is not particularly
safe. Also UBSAN was complaining. Use memcpy into a default constructed
T instead and require that the T be trivially copyable.
We had some inconsistencies before:
- Sometimes "The", sometimes "the"
- Sometimes trailing ".", sometimes no trailing "."
I picked the most common one (lowecase "the", trailing ".") and applied
it to all copyright headers.
By using the exact same string everywhere we can ensure nothing gets
missed during a global search (and replace), and that these
inconsistencies are not spread any further (as copyright headers are
commonly copied to new files).
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

This was done with the `ambr` search and replace tool.

Calling memcpy with null pointers results in undefined behaviour, even
if count is zero.
This in turns is exploited by GCC. For example, the following code:
memcpy (dst, src, n);
if (!src)
return;
src[0] = 0xcafe;
will be optimized as:
memcpy (dst, src, n);
src[0] = 0xcafe;
IOW the test for NULL is gone.
This is basically just for consistency, it's quite strange to see
multiple AK container types next to each other, some with and some
without the namespace prefix - we're 'using AK::Foo;' a lot and should
leverage that. :^)
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
