This patch adds the CMAKE_BUILD define and skips the opposite test on
Windows. E.g.: With config = Debug, the loadReleasePlugin() test is

The requirement to separate debug and release DLLs on Windows stems from
the Visual Studio C run-time library appearing in two different variants
(debug and release) and not mixing well. It's possible to perform builds
without optimzations and with debug symbols while linking against the
release version of the C run-time, but at the same time the debug
version of the run-time brings other developer visible advantages.
MinGW on the other hand does not have this distinction, does not ship
with separate DLLS and does also not require the VS C runtime library.
Therefore we do not need this separation for MinGW, which means that our
packages can be reduced in size and application developers wishing to
debug their applications do not have to use debug builds of the Qt
libraries or run into Qt internal debug code.

...not just the debug flag. The information is saved outside of the CBOR
map for two reasons:
1) removing the hack that depended on how QCborStreamWriter and
TinyCBOR internally work, allowing for the extra parameter to be
written directly. We wouldn't be able to use that hack anyway and would
have needed a further, uglier hack to encode a byte whose value we
don't know.
2) outside the map, this information can be parsed more quickly and
then we can discard any plugins we shouldn't actually load.
Since we're doing this for a flag, I decided to move the Qt version
there too for reason #2.

I've had to change the signature so older versions of Qt won't try to

When using actual memory allocation, limit to 64 MB, not the full file
size. On most systems, the memory map technique will work, so this won't
even be tried. In any case, we don't need the fix for the OOM situation
that was applied in commit e211ab76d7.
As for the memory mapping technique, this commit limits the allocation
to reasonable values given the virtual memory addressing space. Half a
gigabyte is probably acceptable on 32-bit systems, where there should be
a contiguous space for the OS to allocate the file in. This commit also
fixes an overflow when converting from qint64 of the file size to ulong
(32-bit on 32-bit platforms and on Windows).

This test executable was not flaky in the normal sense that when run, it
sometimes passes and sometimes fails. Instead, in some builds it would fail
consistently and in some builds it would pass consistently.
The first test to fail was version(ok00, default to last version) which gives
"mylib" as the library name and -1 as the library version. The description
implies that QLibrary selects the biggest or last used version when given -1.
However, versions less than 0 are not used at all. Instead the loading uses only
the name to select the library. Change the description to match.
So why did the test sometimes pass, sometimes fail? The test uses two library
projects lib and lib2 which install two different major versions of libmylib.
That includes the symbolic links:
libmylib.so -> libmylib.so.1.0.0*
libmylib.so.1 -> libmylib.so.1.0.0*
libmylib.so.1.0 -> libmylib.so.1.0.0*
libmylib.so.1.0.0*
libmylib.so -> libmylib.so.2.0.0*
libmylib.so.2 -> libmylib.so.2.0.0*
libmylib.so.2.0 -> libmylib.so.2.0.0*
libmylib.so.2.0.0*
The key thing being that both set the libmylib.so symbolic link. In a
multithreaded installation it's undefined which happens to set the link last.
The test code expected libmylib.so to point to libmylib.so.2.0.0. Ensure that by
building and installing lib2 after lib.

Usually, when you load a plugin, you don't want to load just any plugin
that fulfills a given interface, but rather a specific one. When loading
dynamic plugins you can differentiate the plugins by file name. This
doesn't work in the static case, and file names are also separate from
the plugin metadata shipped inside the plugin files.
To solve this problem, different hacks have been developed in various
places. QML extension plugins add a special property "uri" via the -M
option of moc, QML debug plugins expect you to add a json file with
an array of "Keys", Qt Creator plugins have a "Name" in their json
files, etc.
By allowing the identifier for the plugin to be specified inline with
the metadata declaration we can make many of the above workarounds
obsolete and provide a clean way for users to find their plugins.

As for the formatting code, de-duplicate the parsing code by only
parsing char*s, converting QChars to Latin-1 first in a small buffer.
The QUuid(const char*) ctor performed no length checking, relying
instead on the checks performed within _q_uuidFromHex(), which
includes an implicit check for premature end (because NUL is not
a valid token for the parser).
The (QString) and (QByteArray) ctors did perform length checking.
To the extent possible, this is removed, since it is handled by
_q_uuidFromHex(). Failure cases need not be optimized. Only the
QLatin1String overload needs to do some checking, because views in
general are not NUL-terminated. The QStringView overload can just
append a NUL when it converts to Latin-1.
The only check I added to _q_uuidFromHex() is that for src ==
nullptr. It would otherwise be duplicated in several callers.
While touching the internal functions, port to passing and returning
by value.
