This partially reverts commit e486d69133.
It broke too many users, even though all of them deserved to be broken.
The new functionality will be provided by differently-named functions,
where possible (problem: equality operators).
I did not revert the fix for the off-by-one error in
tst_qtextdocumentfragment.cpp.
I also didn't revert the change in the inequality relational operators,
since for all strings s1, s2 and s2' where s2' is s2 truncated at the
first NUL, s1 < s2 ⟺ s1 < s2' (since NUL < c for any c != 0), and,
trivially, for ≤, >, ≥, too. This does not hold for = and ≠, of course,
since "foo\0bar" ≠ "foo".

Currently, calling these functions with a null QByteArray will return
a non-null QString because QByteArray::data() never returns nullptr.
This behavior leads to inconsistencies between QString::append overloads,
in particular the QByteArray vs. all others (null + null test always
returns a null QString, except for the QByteArray overload before this
change).
It also is inconsistent with the const char* overloads of these methods,
which explicitly preserve nullness (as verified by test cases).
Fixed by an explicit check for nullness and return of null QString.
Alternative would have been to check for nullness and pass nullptr
instead of ba.data() to the _helper() functions, which do the correct
thing in that case. But since we'd have the check anyway and with the
chosen strategy we can avoid a call to a non-inline method, I opted
against that.

and 272 out of 441 in Qt Creator. For simplified, the numbers are 27 out

uses of left, right and mid on an xvalue QString or QByteArray in Qt.
