They share so many things, and QMAC is lacking so many of the changes
QCH has received over the last few months, that it seems QMAC is
better off being implemented in the QCH TU.
Among other things, this will allow QMAC to use QCHPrivate for its
implementation, drastically reducing the number of memory allocations
required to perform HMAC operations.

While QMessageAuthenticationCode is not copyable, result() is
nevertheless const, so a user could prepare a
QMessageAuthenticationCode object with setKey() and addData(), pass it
by const reference to two threads, which each just call result() on
it. This should be safe, but because result() performed lazy
evaluation without being internally synchronized, this would cause
data races.

performance at runtime instead. But somewhere along the line, either
when they were added, when C++20 <bit> support was, or in any of the
bugfixes for other compilers, the nesting of #ifdef got messed up and we
declared that we had constexpr builtins for MSVC in C++17 too.

When Qt is configured to return nullptr from isNull() QStrings
(QT5_NULL_STRINGS != 1), then we'd be feeding a nullptr src into
strncpy(), which is UB. I couldn't rule the case of a null QString
lexeme out with local reasoning, seeing as the code is in the else
branch of an if (lexeme.startsWith(~~~) && lexeme.endsWith(~~~)), so
it might be null.
Instead of porting to qstrncpy(), which can deal with a nullptr src
(albeit up to recently, badly), note that the strncpy + the char[]
allocation is a qstrdup(), so use that instead. This also does away
with the queasiness of taking the size() of a UTF-16 string to limit
strncpy() for the L1-recoded version (which, in this instance is safe,
as toLatin1().constData() is NUL-terminated, but in some other
instances was not).
As a drive-by, make sure we don't leak the strdup()'ed string if the
emplace_back() fails.

The only user of the function, QCollatorPrivate::init(), passes
QLocalePrivate::bcp47Name().constData(). bcp47Name() may return a
default-constructed QByteArray (e.g. for QLocale::AnyLanguage), so
constData() may be nullptr (QT5_NULL_STRINGS != 1). Passing nullptr to
strncmp() or strncpy() is UB, though.
Instead of using the nullptr-hardened q... versions of these
functions, check name for nullptr once, at the top of the function,
and avoid all the lookup code that follows and is known to fail
(because windows_to_iso_list does not contain empty entries).
This way, we take advantage of the std functions' UB for performance
reasons (fewer repeated nullptr checks), instead of being taken
advantage of.
