asprintf() is a GNU extension that prints into a string it
allocates internally. Arguably, that's a better name for
QString::sprintf() since it also allocates memory internally.
The main problem with QString::sprintf() isn't that it's
dangerous to use (it is), but that it's not static. It also
returns a reference instead of by-value, breaking RVO.
There is a comment about removing this function completely
in Qt 6.0, but it remains the only printf-style function
in Qt that can allocate the target string, so it's vital
for logging, e.g., and the recommended replacement code
(http://linux.die.net/man/3/vsnprintf) is a nightmare.
So this patch adds static (v)asprintf() methods to replace it.
Further patches will fix up all in-tree callers and finally
deprecate the old (v)sprintf().
Test coverage is provided through the existing tests of
sprintf(), which is implemented in terms of asprintf().
Arguably, the in-tree callers show that QByteArray would
benefit from having an asprintf(), too, as most of the
in-tree code works around its lack with calls
to to{Latin1,Local8Bit}() after using the QString version.
[ChangeLog][QtCore][QString] Added asprintf(), vasprintf().

This code is C++ only. There isn't a single C++ compiler that fails to
understand the "inline" keyword, since it's required by C++98. Any
compiler older than C++98 is likely to choke on the template usage
further down, so this isn't necessary.
Moreover, the C++ standard says you cannot define macros.
[lib.macro.names] says "Nor shall such a translation unit define macros
for names lexically identical to keywords." -- technically, it's a
promise that the Standard Library headers won't do it, the wording means
that the entire translation unit won't do it, which implies no source
can do it.
MSVC complains about it:

This enables us to do more intelligent distribution than simply doing the
rounding on each individual items geometry (which often leads to larger
spacings than specified).
Instead of doing the rounding on the output geometries, we now do the
snapping inside the layout engine. This allows us to do more intelligent
distribution of items, and spacings should always be respected.
There are some cases where items with fractional size hints might overlap
with less than a pixel. This was also the case before this patch. Those
cases are impossible to fix properly, since fractional size hints
conflicts with the snapping in some cases.
(Fractional size hints is normal for Text items.)

Previous errors in versioned function classes for OpenGL versions
prior to 4.4 have also been fixed to comply with the new OpenGL
xml specification. Such mistakes were due to either bugs in the
old plain text specification files or problems due to the
difficulty in parsing the old spec files.
In some cases this has meant adding in missing functions that were
absent previously.
The other class of problem was when functions were erroneously
included in the versioned function classes when they should not
have been present. That is, some core profile classes incorrectly
had member functions for deprecated functions that should only
be present in the compatibility profile classes. In these cases
these incorrect functions will now trigger a qFatal if
called. This is fine as any applications that called these by mistake
in the past would have been dereferencing a null pointer as the
function pointer resolution would have failed for these functions.

Try making it compatible with QOpenGLContext::functions() which returns
an already initialized QOpenGLFunctions.
Unfortunately we cannot make them 100% compatible because functions()
conveniently requires that the context (or a sharing context) is current.
versionFunctions() has no such requirement and we cannot safely introduce
it anymore.
What we can do is to state that as long as the context is the current one,
the initializeOpenGLFunctions() call can be omitted. If another context (or
no context) is current, the call will still be needed, like it is today.
Also, we require that the exact same context is current. Sharing does not
count since the exact behavior of sharing contexts with different versions
is unknown.
