9baf69c765 rhi: gl: Add a feature flag for reading back non-zero mip levels
The joys of "level - Specifies the mipmap level of the texture
image to be attached, which must be 0." for glFramebufferTexture2D
in OpenGL ES 2.0.

32924110ce rhi: gl: Switch GetBufferSubData emulation to MapBufferRange
Use only APIs that are in GLES 3.0.

glMapBuffer() is an old OES extension, stop bothering with that.
Not the least because ANGLE claims supporting it and then fails the
map. (not that we care much about ANGLE, but, for instance, the qrhi
autotest is run with ANGLE configurations as well in the CI, so have
to still take care of it for the duration of Qt 5.x)

9c466946d0 rhi: Autotest basic texture operations
...and make the Null backend able to deal with these, for RGBA8 textures
at least. Naturally it is all QImage and QPainter under the hood.

Also fix a bug in the OpenGL backend, as discovered by the autotest:
the size from the readback did not reflect the mip level.

e22399af82 Make QRhi::create() return false when there is no MTLDevice
The interesting part here is that sending messages to a null
object is valid in Objective-C, so without an explicit check it
is not necessarily straightforward to discover that we do not
have working rendering. (because the application won't just
simply crash)

Do the right thing now and return false like other backends do.

89ec1b3618 rhi: Add support for buffer readbacks
This also marks the beginnings of significantly extending autotesting
of the resource and rendering functionality in QRhi.

Also involves fixing up the buffer operation lists like we did
for textures before. This is to ensure updates and reads on the
same batch execute in the correct order. So just have two lists:
one with buffer, one with texture operations.

Also simplify the struct layouts. No need for those inner structs
with many duplicate members. This reduces the size even, since using a
union was never an option here. Also switch to a VLA, the size is around
253 KB per batch.

The Null backend now keeps track of the QRhiBuffer data so it can return
valid results in readbacks.

a6ffdbe30c QTextCodec: try to work around an ICC 19 bug
ICC 19 barfs on the TextCodecsMutexLocker class because it doesn't
have a user-provided default ctor:

  ../../corelib/codecs/qtextcodec.cpp(543): error #854: const variable locker requires an initializer -- class TextCodecsMutexLocker has no user-provided default constructor
  [...]

But the class doesn't have members that would delete the
implictly-declared default ctor, so no user-provided default ctor
should be necessary:

The only member is the result of qt_unique_lock(), which is
std::unique_lock, which does have a default ctor.

We conclude that this is a compiler bug, and work around it with the
introduction of a user-provided default ctor.

Fix brace placement as a drive-by.

0118e2e915 Include likely-adjusted uiLanguages for the system locale
QLocale::uiLanguages() on the system locale uses whatever the system
locale's query(QSystemLocale::UILanguages,...) returns. On Android,
this is just a list of locales. However, for non-system locales, we
also include some results of removing likely sub-tags from the locale
name, where equivalent. Thus zh-CN would also get zh and zh-Hans-CN
added to it; however, if the system locale is zh-Hans-CN, the shorter
forms are omitted. So post-process the system locale list in the same
way, albeit tweaked to avoid duplicates and rearranged so that we can
insert likely-adjusted entries between what they adjust and what
followed it.

Added QLocalePrivate::rawName() in the process, since it looks likely
to be useful in other contexts (and I needed its value): it just joins
such tags as are non-Any. This, however, uses QByteArrayList, so added
that (it's small) to the bootstrap library and qmake.

This follows up on commit 8796e3016f.

[ChangeLog][QtCore][QLocale] The system locale's UI languages list now
includes, as for that of an ordinary locale, the results of adding
likely sub-tags from each locale name, and of removing some, where
this doesn't change which locale is specified. This gives searches for
translation files a better chance of finding a suitable file.

5aa13ea144 QTreeWidget: Don't assume the selected indexes include the first column
If the first column is hidden in a QTreeWidget then when doing a drag
then the selected indexes will not include any that have a column of 0.
Therefore it has to account for this use std::unique to ensure that
there is only one instance of the selected items represented by the
selected indexes.

74abe98320 qmake: Place prl files under Resources in framework bundles
The root of the framework bundle shouldn't contain random files,
and doing so will prevent the bundle from being signable.

We still look up prl files in the root, to keep backwards
compatibility.

b4efdd3769 Reorganise the qfloat16 auto-test
Its limits() test was rather large and had some overlap with an older
qNan() test, that needed some clean-up (it combined qfloat16 values
with double and float values in ways that caused qfloat16 to be
promoted to another type, so we weren't testing qfloat16).

Renamed the qNan() test to qNaN(), separated out the parts of it that
actually tested infinity. Moved various parts of limits() to these and
rationalised the result. Split out a properties() test from limits()
for the properties of the qfloat16 type that are supplied by its
numeric_limits. Split out a data-driven finite() test to cover some
repeated code that was in limits() and extended it to test more
values. Added more tests of isNormal().

Fixed my earlier UK-ish spelling of "optimise", in the process, and
identify the processor rather than the virtualization as the context
where the compiler errs.

2e068c7f2a Add TriangleFan pipeline topology
Triangle fan drawing is only supported on some platforms. The feature
flag QRhi::TriangleFanTopology is set accordingly.

In general, TriangleStrip topology will be more efficient on most GPUs.
However, if polygon data is already stored as triangle fans, the CPU
savings may be more significant.
