It was confusing entry capacity with the bucket capacity. The value
maxNumBuckets() returned was the maximum number of entries. This issue
was harmless: we would just fail to cap the maximum to an allocatable
size. But the array new[] in the Data constructors would have capped the
maximum anyway (by way of throwing std::bad_alloc).
So instead of trying to calculate what the maximum bucket count is so we
can cap at that, simplify the calculation of the next power of 2 while
preventing it from overflowing in our calculations. We continue to rely
on new[] throwing when we return count that is larger than the maximum
allocatable.
This commit changes the load factor for QHashes containing exactly a
number of elements that is exactly a power of two. Previously, it would
be loaded at 50%, now it's at 25%. For this reason, tst_QSet::squeeze
needed to be fixed to depend less on the implementation details.

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.
